cmake: add BUILD_EXAMPLES option to build examples
You can enable it with `-DBUILD_EXAMPLES=ON`.

To match autotools' `make examples` feature.
Windows (static) builds not tested.

Also enable examples in a pair of CI jobs.

Apply related updates to the macOS CI workflow:
- drop unused `CXX` envs.
- drop no longer needed `-Wno-error=undef -Wno-error=conversion` flags.
- pass `-Wno-deprecated-declarations` to GCC too (for `BUILD_EXAMPLES`).
- document why `-Wno-deprecated-declarations` is necessary.

idn: add native AppleIDN (icucore) support for macOS/iOS
I implemented the IDN functions for macOS and iOS using Unicode
libraries coming with macOS and iOS.

Builds and runs here on macOS 14.2.1. Also verified to load and
run on older macOS version 10.13.

Build requires macOS SDK 13 or equivalent.

Set `-DUSE_APPLE_IDN=ON` CMake option to enable it.
With autotools and other build tools, set these manual options:
```
CPPFLAGS=-DUSE_APPLE_IDN
LIBS=-licucore
```

Completes TODO 1.6.

build: prefer USE_IPV6 macro internally (was: ENABLE_IPV6)
Before this patch, two macros were used to guard IPv6 features in curl
sources: `ENABLE_IPV6` and `USE_IPV6`. This patch makes the source use
the latter for consistency with other similar switches.

`-DENABLE_IPV6` remains accepted for compatibility as a synonym for
`-DUSE_IPV6`, when passed to the compiler.

`ENABLE_IPV6` also remains the name of the CMake and `Makefile.vc`
options to control this feature.

This syncs behaviour with autotools.

cmake: fix libcurl.pc and curl-config library specifications
Letting CMake figure out where libraries are located gives you full
paths. When generating libcurl.pc and curl-config, getting libraries as

cmake: fix CURL_WINDOWS_SSPI=ON with Schannel disabled
Prior to this change `CURL_WINDOWS_SSPI` was accidentally forced `OFF`
when building without the Schannel TLS backend.

This in turn may have caused Kerberos, SPNEGO and SSPI features
disappearing even with `CURL_WINDOWS_SSPI=ON` set.

This patch fixes it by using the `CURL_USE_SCHANNEL` setting as a
default for `CURL_WINDOWS_SSPI`, but allowing a manual override.

docs: ascii version of manpage without nroff
Create ASCII version of manpage without nroff

 - build src/tool_hugegelp.c from the ascii manpage
 - move the the manpage and the ascii version build to docs/cmdline-opts
 - remove all use of nroff from the build process
 - should make the build entirely reproducible (by avoiding nroff)

 - partly reverts 2620aa9 to build libcurl option man pages one by one
   in cmake because the appveyor builds got all crazy until I did

The ASCII version of the manpage

 - is built with gen.pl, just like the manpage is
 - has a right-justified column making the appearance similar to the previous
   version
 - uses a 4-space indent per level (instead of the old version's 7)
 - does not do hyphenation of words (which nroff does)

History

  We first made the curl build use nroff for building the hugehelp file in
  December 1998, for curl 5.2.

system.h: sync mingw CURL_TYPEOF_CURL_SOCKLEN_T with other compilers
Align mingw with the other Windows compilers and use the `int` type for
`CURL_TYPEOF_CURL_SOCKLEN_T` (and thus for `curl_socklent_t`). This
makes it unnecessary to make a mingw-specific trick and pull all Windows
headers early just for this type definition. This type is specific to
Windows, not to the compiler. mingw-w64's Windows header maps it to
`int` too.

With this we also delete all remaining uses of `CURL_PULL_WS2TCPIP_H`.

[ The official solution is to use `socklen_t` for all Windows compilers.
In this case we may want to update `curl/curl.h` to pull in Windows
headers before `system.h`. ]

cmake: delete obsolete TODOs more [ci skip]
- manual completed: 898b012a9b #1288
- soname completed: 5de6848f10 #10023
- bunch of others that are completed
- `NTLM_WB_ENABLED` is implemented in a basic form, and now also
  scheduled for removal, so a TODO at this point isn't useful.

And this 'to-check' item:

Q: "The cmake build selected to run gcc with -fPIC on my box while the
   plain configure script did not."

A: With CMake, since 2ebc74c36a #11546
   and fc9bfb1452 #11627, we explicitly
   enable PIC for libcurl shared lib. Or when building libcurl for
   shared and static lib in a single pass. We do this by default for
   Windows or when enabled by the user via `SHARE_LIB_OBJECT`.
   Otherwise we don't touch this setting. Meaning the default set by
   CMake (if any) or the toolchain is used. On Debian Bookworm, this
   means that PIC is disabled for static libs by default. Some platforms
   (like macOS), has PIC enabled by default.
   autotools supports the double-pass mode only, and in that case
   CMake seems to match PIC behaviour now (as tested on Linux with gcc.)

cmake: delete obsolete TODO items [ci skip]
There is always room for improvement, but CMake is up to par now with

Q: "The gcc command line use neither -g nor any -O options. As a
   developer, I also treasure our configure scripts's --enable-debug
   option that sets a long range of "picky" compiler options."

A: CMake offers the `CMAKE_BUILD_TYPE` variable to control debug info
   and optimization level. E.g.:
   - `Release`    = `-O3` + no debug info
   - `MinSizeRel` = `-Os` + no debug info
   - `Debug`      = `-O0` + debug info

family type, which is the same as ADDRESS_FAMILY.

cmake: speed up zstd detection
Before this patch we detected the presence of a specific zstd API to
see if we can use the library. zstd published that API in its first
stable release: v1.0.0 (2016-08-31).

Replace that method by detecting the zstd library version instead and
accepting if it's v1.0.0 or newer. Also display this detected version
and display a warning if the zstd found is unfit for curl.

We use the same version detection method as zstd itself, via its public
C header.

This deviates from autotools which keeps using the slow method of
looking for the API by building a test program. The outcome is the same
as long as zstd keeps offering this API.

cmake: pre-fill rest of detection values for Windows
The goal of this patch is to avoid unnecessary feature detection work
when doing Windows builds with CMake. Do this by pre-filling well-known
detection results for Windows and specifically for mingw-w64 and MSVC
compilers. Also limit feature checks to platforms where the results are
actually used. Drop a few redundant ones. And some tidying up.

- pre-fill remaining detection values in Windows CMake builds.

  Based on actual detection results observed in CI runs, preceding
  similar work over libssh2 and matching up values with
  `lib/config-win32.h`.

  This brings down CMake configuration time from 58 to 14 seconds on the
  same local machine.

  On AppVeyor CI this translates to:
  - 128 seconds -> 50 seconds VS2022 MSVC with OpenSSL (per CMake job):
    https://ci.appveyor.com/project/curlorg/curl/builds/48208419/job/4gw66ecrjpy7necb#L296
    https://ci.appveyor.com/project/curlorg/curl/builds/48217440/job/8m4fwrr2fe249uo8#L186
  - 62 seconds -> 16 seconds VS2017 MINGW (per CMake job):
    https://ci.appveyor.com/project/curlorg/curl/builds/48208419/job/s1y8q5ivlcs7ub29?fullLog=true#L290

  The formula is about 1-3 seconds delay for each detection. Almost all
  of these trigger a full compile-link cycle behind the scenes, slow
  even today, both cross and native, mingw-w64 and apparently MSVC too.
  Enabling .map files or other custom build features slows it down
  further. (Similar is expected for autotools configure.)

- stop detecting `idn2.h` if idn2 was deselected.
  autotools does this.

- stop detecting `idn2.h` if idn2 was not found.
  This deviates from autotools. Source code requires both header and
  lib, so this is still correct, but faster.

- limit `ADDRESS_FAMILY` detection to Windows.

- normalize `HAVE_WIN32_WINNT` value to lowercase `0x0a12` format.

- pre-fill `HAVE_WIN32_WINNT`-dependent detection results.
  Saving 4 (slow) feature-detections in most builds: `getaddrinfo`,
  `freeaddrinfo`, `inet_ntop`, `inet_pton`

- fix pre-filled `HAVE_SYS_TIME_H`, `HAVE_SYS_PARAM_H`,
  `HAVE_GETTIMEOFDAY` for mingw-w64.
  Luckily this do not change build results, as `WIN32` took
  priority over `HAVE_GETTIMEOFDAY` with the current source
  code.

- limit `HAVE_CLOCK_GETTIME_MONOTONIC_RAW` and
  `HAVE_CLOCK_GETTIME_MONOTONIC` detections to non-Windows.
  We're not using these in the source code for Windows.

- reduce compiler warning noise in CMake internal logs:
  - fix to include `winsock2.h` before `windows.h`.
    Apply it to autotools test snippets too.
  - delete previous `-D_WINSOCKAPI_=` hack that aimed to fix the above.
  - cleanup `CMake/CurlTests.c` to emit less warnings.

- delete redundant `HAVE_MACRO_SIGSETJMP` feature check.
  It was the same check as `HAVE_SIGSETJMP`.

- delete 'experimental' marking from `CURL_USE_OPENSSL`.

- show CMake version via `CMakeLists.txt`.
  Credit to the `zlib-ng` project for the idea:
  61e181c8ae/CMakeLists.txt (L7)

- make `CMake/CurlTests.c` pass `checksrc`.

- `CMake/WindowsCache.cmake` tidy-ups.

- replace `WIN32` guard with `_WIN32` in `CMake/CurlTests.c`.

configure: check for the fseeko declaration too
... and make the code require both symbol and declaration.

This is because for Android, the symbol is always present in the lib at
build-time even when not actually available in run-time.

cmake: fix OpenSSL quic detection in quiche builds
An orphan call to `CheckQuicSupportInOpenSSL()` remained after a recent
update when checking QUIC for quiche. Move back QUIC detection to
a function and fixup callers to use that. Also make sure that quiche
gets QUIC from BoringSSL, because it doesn't support other forks at this
time.

e160d17a02 build: fix 'threadsafe' feature detection for older gcc
- Add 'threadsafe' to the feature list shown during build if POSIX
  threads are being used.

This is a follow-up to 5adb6000 which added support for building a
thread-safe libcurl with older versions of gcc where atomic is not
available but pthread is.

cmake: replace check_library_exists_concat()
The idea of `check_library_exists_concat()` is that it detects an
optional component and adds it to the list of libs that we also use in
subsequent component checks. This caused problems when detecting
components with unnecessary dependencies that were not yet built.

CMake offers the `CMAKE_REQUIRED_LIBRARIES` variable to set libs used
for component checks, which we already use in most cases. That left 4
uses of `check_library_exists_concat()`. Only one of these actually
needed the 'concat' feature (ldap/lber).

Delete this function and replace it with standard
`check_library_exists()` and manual management of our `CURL_LIBS`
list we use when linking build targets. And special logic to handle the
ldap/lber case.

(We have a similar function for headers: `check_include_file_concat()`.
It works, but problematic for performance reasons and because it hides
the actual headers required in `check_symbol_exists()` calls.)

build: do not publish HAVE_BORINGSSL, HAVE_AWSLC macros
Syncing this up with CMake.

Source code uses the built-in `OPENSSL_IS_AWSLC` and
`OPENSSL_IS_BORINSSL` macros to detect BoringSSL and AWS-LC. No help is
necessary from the build tools.

The one use of `HAVE_BORINGSSL` in the source turned out to be no longer
necessary for warning-free BoringSSL + Schannel builds. Ref: #1610 #2634

autotools detects this anyway for display purposes.
CMake detects this to decide whether to use the BoringSSL-specific
crypto lib with ngtcp2. It detects AWS-LC, but doesn't use the detection
result just yet (planned in #12066).

cmake: improve OpenLDAP builds
- cmake: detect OpenLDAP based on function `ldap_init_fd`.
  autotools does this. autotools also publishes this detection result
  in `HAVE_LDAP_INIT_FD`. We don't mimic that with CMake as the source
  doesn't use this value. (it might need to be remove-listed in
  `scripts/cmp-config.pl` for future OpenLDAP test builds.)
  This also deletes existing self-declaration method via the
  CMake-specific `CURL_USE_OPENLDAP` configuration.

- cmake: define `LDAP_DEPRECATED=1` for OpenLDAP.
  Like autotools does. This fixes a long list of these warnings:
  ```
  /usr/local/opt/openldap/include/ldap.h:1049:5: warning: 'LDAP_DEPRECATED' is not defined, evaluates to 0 [-Wundef]
  ```

- cmake: delete LDAP TODO comment no longer relevant.

Also:

- autotools: replace domain name `dummy` with `0.0.0.0` in LDAP feature
  detection functions.
