To avoid abuse. The limit is set to 300 KB for the accumulated size of
all received HTTP headers for a single response. Incomplete research
suggests that Chrome uses a 256-300 KB limit, while Firefox allows up to
1MB.

- check in h2 filter recv that stream actually exists
and return error if not
- add test for parallel, extreme h2 upgrades that fail if
connections get reused before fully switched
- add h2 upgrade upload test just for completeness
Closes#11563
Add `test1279` to verify that `libcurl.def` lists all exported API
functions found in libcurl headers.
Also:
- extend test suite XML `stdout` tag with the `loadfile` attribute.
- fix `tests/extern-scan.pl` and `test1135` to include websocket API.
- use all headers (sorted) in `test1135` instead of a manual list.
- add options `--sort`, `--heading=` to `tests/extern-scan.pl`.
- add `libcurl.def` to the auto-labeler GHA task.

It was previously unlimited by default, but that's not a sensible
default. While changing this has a remote risk of breaking an existing
use case, I figure it is more likely to actually save users from loops.
Closes#11581
- If the user set a legacy algorithm list (CURLOPT_SSL_CIPHER_LIST) then
use the SCHANNEL_CRED legacy structure to pass the list to Schannel.
- If the user set both a legacy algorithm list and a TLS 1.3 cipher list
then abort.
Although MS doesn't document it, Schannel will not negotiate TLS 1.3
when SCHANNEL_CRED is used. That means setting a legacy algorithm list
limits the user to earlier versions of TLS.
Prior to this change, since 8beff435 (precedes 7.85.0), libcurl would
ignore legacy algorithms in Windows 10 1809 and later.

Previously it would always do PF_UNSPEC if CURL_IPRESOLVE_V4 is not

- cache more Windows config results for faster initialization.
- delete unused config macros `HAVE_SYS_UTSNAME_H`, `HAVE_SSL_H`.

EGD is Entropy Gathering Daemon, a socket-based entropy source supported
by pre-OpenSSL v1.1 versions and now deprecated. curl also deprecated it
a while ago.
Its detection in CMake was broken all along because OpenSSL libs were
not linked at the point of feature check.
Delete detection from both cmake and autotools, along with the related
source snippet, and the `--with-egd-socket=` `./configure` option.
Closes#11556
- fix check for availability of nghttpx server
- add `tcp` frontend config for same port as quic, as
without this, port 3000 is bound which clashes for parallel
testing

Bug: https://curl.se/mail/lib-2023-07/0045.htmlCloses#11557
Before this patch CMake builds used two separate compilation passes to
build the shared and static libcurl respectively. This patch allows to
reduce that to a single pass if the target platform and build settings
allow it.
This reduces CMake build times when building both static and shared
libcurl at the same time, making these dual builds an almost zero-cost
option.
Enable this feature for Windows builds, where the difference between the
two passes was the use of `__declspec(dllexport)` attribute for exported
API functions for the shared builds. This patch replaces this method
with the use of `libcurl.def` at DLL link time.
Also update `Makefile.mk` to use `libcurl.def` to export libcurl API
symbols on Windows. This simplifies (or fixes) this build method (e.g.
in curl-for-win, which generated a `libcurl.def` from `.h` files using
an elaborate set of transformations).
`libcurl.def` has the maintenance cost of keeping the list of public
libcurl API symbols up-to-date. This list seldom changes, so the cost
is low.
Closes#11546

While here, also fix `RAND_egd()` detection which was broken, likely all
along. This feature is probably broken with CMake builds and also
requires a sufficiently obsolete OpenSSL version, so this part of the
update was not tested.
Closes#11555
- Update the OpenSSL connect state machine to handle
SSL_ERROR_WANT_RETRY_VERIFY.
This allows libcurl users that are using custom certificate validation
to suspend processing while waiting for external I/O during certificate
validation.
Closes https://github.com/curl/curl/pull/11499
- Suppress an incomplete UTF-8 sequence at the end of the buffer.
- Attempt to reconstruct incomplete UTF-8 sequence from prior call(s)
in current call.
Prior to this change, in Windows console UTF-8 sequences split between
two or more calls to the write callback would cause invalid "replacement
characters" U+FFFD to be printed instead of the actual Unicode
character. This is because in Windows only UTF-16 encoded characters are
printed to the console, therefore we convert the UTF-8 contents to
UTF-16, which cannot be done with partial UTF-8 sequences.
