cmake: add support for "unity" builds Aka "jumbo" or "amalgamation" builds. It means to compile all sources per target as a single C source. This is experimental. You can enable it by passing `-DCMAKE_UNITY_BUILD=ON` to cmake. It requires CMake 3.16 or newer. It makes builds (much) faster, allows for better optimizations and tends to promote less ambiguous code. Also add a new AppVeyor CI job and convert an existing one to use "unity" mode (one MSVC, one MinGW), and enable it for one macOS CI job. Fix related issues: - add missing include guard to `easy_lock.h`. - rename static variables and functions (and a macro) with names reused across sources, or shadowed by local variables. - add an `#undef` after use. - add a missing `#undef` before use. - move internal definitions from `ftp.h` to `ftp.c`. - `curl_memory.h` fixes to make it work when included repeatedly. - stop building/linking curlx bits twice for a static-mode curl tool. These caused doubly defined symbols in unity builds. - silence missing extern declarations compiler warning for ` _CRT_glob`. - fix extern declarations for `tool_freq` and `tool_isVistaOrGreater`. - fix colliding static symbols in debug mode: `debugtime()` and `statename`. - rename `ssl_backend_data` structure to unique names for each TLS-backend, along with the `ssl_connect_data` struct member referencing them. This required adding casts for each access. - add workaround for missing `[P]UNICODE_STRING` types in certain Windows builds when compiling `lib/ldap.c`. To support "unity" builds, we had to enable `SCHANNEL_USE_BLACKLISTS` for Schannel (a Windows `schannel.h` option) _globally_. This caused an indirect inclusion of Windows `schannel.h` from `ldap.c` via `winldap.h` to have it enabled as well. This requires `[P]UNICODE_STRING` types, which is apperantly not defined automatically (as seen with both MSVS and mingw-w64). This patch includes `<subauth.h>` to fix it.

build: fix circular header inclusion with other packages This commit renames lib/setup.h to lib/curl_setup.h and renames lib/setup_once.h to lib/curl_setup_once.h. Removes the need and usage of a header inclusion guard foreign to libcurl. [1] Removes the need and presence of an alarming notice we carried in old setup_once.h [2] ---------------------------------------- 1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H, this single inclusion guard is enough to ensure that inclusion of lib/setup_once.h done from lib/setup.h is only done once. Additionally lib/setup.h has always used __SETUP_ONCE_H macro to protect inclusion of setup_once.h even after commit ec691ca3, this was to avoid a circular header inclusion triggered when building a c-ares enabled version with c-ares sources available which also has a setup_once.h header. Commit ec691ca3 exposes the real nature of __SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard foreign to libcurl belonging to c-ares's setup_once.h The renaming this commit does, fixes the circular header inclusion, and as such removes the need and usage of a header inclusion guard foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl. 2 - Due to the circular interdependency of old lib/setup_once.h and the c-ares setup_once.h header, old file lib/setup_once.h has carried back from 2006 up to now days an alarming and prominent notice about the need of keeping libcurl's and c-ares's setup_once.h in sync. Given that this commit fixes the circular interdependency, the need and presence of mentioned notice is removed. All mentioned interdependencies come back from now old days when the c-ares project lived inside a curl subdirectory. This commit removes last traces of such fact.

build: add more picky warnings and fix them Enable more picky compiler warnings. I've found these options in the nghttp3 project when implementing the CMake quick picky warning functionality for it [1]. `-Wunused-macros` was too noisy to keep around, but fixed a few issues it revealed while testing. - autotools: reflect the more precisely-versioned clang warnings. Follow-up to 033f8e2a08eb1d3102f08c4d8c8e85470f8b460e #12324 - autotools: sync between clang and gcc the way we set `no-multichar`. - autotools: avoid setting `-Wstrict-aliasing=3` twice. - autotools: disable `-Wmissing-noreturn` for MSYS gcc targets [2]. It triggers in libtool-generated stub code. - lib/timeval: delete a redundant `!MSDOS` guard from a `WIN32` branch. - lib/curl_setup.h: delete duplicate declaration for `fileno`. Added in initial commit ae1912cb0d494b48d514d937826c9fe83ec96c4d (1999-12-29). This suggests this may not be needed anymore, but if it does, we may restore this for those specific (non-Windows) systems. - lib: delete unused macro `FTP_BUFFER_ALLOCSIZE` since c1d6fe2aaa5a26e49a69a4f2495b3cc7a24d9394. - lib: delete unused macro `isxdigit_ascii` since f65f750742068f579f4ee6d8539ed9d5f0afcb85. - lib/mqtt: delete unused macro `MQTT_HEADER_LEN`. - lib/multi: delete unused macro `SH_READ`/`SH_WRITE`. - lib/hostip: add `noreturn` function attribute via new `CURL_NORETURN` macro. - lib/mprintf: delete duplicate declaration for `Curl_dyn_vprintf`. - lib/rand: fix `-Wunreachable-code` and related fallouts [3]. - lib/setopt: fix `-Wunreachable-code-break`. - lib/system_win32 and lib/timeval: fix double declarations for `Curl_freq` and `Curl_isVistaOrGreater` in CMake UNITY mode [4]. - lib/warnless: fix double declarations in CMake UNITY mode [5]. This was due to force-disabling the header guard of `warnless.h` to to reapply it to source code coming after `warnless.c` in UNITY builds. This reapplied declarations too, causing the warnings. Solved by adding a header guard for the lines that actually need to be reapplied. - lib/vauth/digest: fix `-Wunreachable-code-break` [6]. - lib/vssh/libssh2: fix `-Wunreachable-code-break` and delete redundant block. - lib/vtls/sectransp: fix `-Wunreachable-code-break` [7]. - lib/vtls/sectransp: suppress `-Wunreachable-code`. Detected in `else` branches of dynamic feature checks, with results known at compile-time, e.g. ```c if(SecCertificateCopySubjectSummary) /* -> true */ ``` Likely fixable as a separate micro-project, but given SecureTransport is deprecated anyway, let's just silence these locally. - src/tool_help: delete duplicate declaration for `helptext`. - src/tool_xattr: fix `-Wunreachable-code`. - tests: delete duplicate declaration for `unitfail` [8]. - tests: delete duplicate declaration for `strncasecompare`. - tests/libtest: delete duplicate declaration for `gethostname`. Originally added in 687df5c8c39c370a59999b9afc0917d808d978b7 (2010-08-02). Got complicated later: c49e9683b85ba9d12cbb6eebc4ab2c8dba68fbdc If there are still systems around with warnings, we may restore the prototype, but limited for those systems. - tests/lib2305: delete duplicate declaration for `libtest_debug_config`. - tests/h2-download: fix `-Wunreachable-code-break`.
