Add test1715 to check proper handling of chunked transfer
encoding in CONNECT responses. Change proxy error code from
56 (RECV_ERROR) for everything to 7 (COULDNT_CONNECT) when
the server response could be read successfully, but establishing
the connection is not possible (http status code wrong).
Adapt several test expectations from 56 to 7.
Closes#21084
Use a thread queue and pool for asnyc threaded DNS resolves.
Add pytest test_21_* for verification.
Add `CURLMOPT_RESOLVE_THREADS_MAX` to allow applications to
resize the thread pool used.
Add `CURLMOPT_QUICK_EXIT` to allow applications to skip thread
joins when cleaning up a multi handle. Multi handles in
`curl_easy_perform()` inherit this from `CURLOPT_QUICK_EXIT`.
Add several debug environment variables for testing.

Verify if lines are not longer than 192 characters. Also verify if lines
have less than 79 repeat spaces (and fix one fallout).
To improve readability by avoiding long lines and to prevent adding
overly long lines with text that may go unnoticed in an editor or diff
viewer.
In addition to pre-existing line length limits: 79 for C, 132 for CMake
sources.
Also:
- spacecheck: fix/harden allowlist regexes.
- spacecheck: tidy-up quotes and simplify escaping.
- spacecheck: allow folding strings with repeat spaces.
- GHA: fix a suppressed shellcheck warning.
- GHA/macos: simplify by dropping brew bundle.
- test1119.pl: precompile a regex.
- FAQ.md: delete very long link to a Windows 7/2008 support article
that's lost it relevance.
Closes#21087
On any `Curl_rlimit_start()` the rate limit needs to reset its
values before calculating the effective step duration and adjust
the tokens/burst per step.
Add two fields to the struct to remember the original values.
Closes#21086
The previously documented version was based on version checks made in
the source. In practice though, curl doesn't build with <5.0.0.
Also:
- bump main internal version check.
- drop superfluous internal version checks.
Closes#21080
Memory returned from curl_easy_escape() should be fred with curl_free()
to avoid surprises.

Closes#21075
By passing command-line as separate arguments instead of using a single
string. This needs skipping the shell, so rework redirections to use
Perl `open3()`.
Also explored to use `-out` to avoid redirections, but it makes the
command-line incompatible with some OpenSSL implementations/versions
(e.g. on default macOS), and would still need a solution for
`2>/dev/null`.

The two bitmask constants for *CLEAR_DNS and *CLEAR_CONNS were
duplicates (both set to 1), so they cannot be distinguished and both
actions fire.
This shipped in public releases since 8.16.0 to and include 8.19.0.
This fix adds CURLMNWC_CLEAR_ALL to be the new 1, and it now implies all
bits. The DNS and CONNS defines get two new bits (2, 4).

PowerPC64 (both big-endian and little-endian) supports efficient
unaligned memory access, similar to x86. This extends the existing
fast path that avoids byte-by-byte loads in the MD5 and MD4 SET/GET
macros.
On POWER8 ppc64le, this eliminates 3 shifts + 3 ORs per 32-bit word
load, replacing them with a single lwz (or lwbrx on big-endian).

Closes#21049
The code runs under different rules than documentation and these checks
cause too much friction with too little gain.
Leave checking of the public include files since they are almost
documentation.
Closes#21048
The code failed to check for the version, and could thus read memory
past the existing curl_version_info_data structure. This could lead to a
crash.
Closes#21050
After limiting `find_package()`/`find_dependency()` calls to curl local
Find modules via the `MODULES` keyword, it became possible to detect
dependencies via CMake Configs from within those local Find modules, by
calling `find_package()` again with the `CONFIG` keyword. This patch
implements this. Then maps detection results to the result variables and
curl-specific imported targets the rest of the build expects.
Also honor recently introduced `*_USE_STATIC_LIBS` (experimental) flags
to map to the static target when requested.
This adds CMake Configs as an alternative to the existing `pkg-config`
and `find_path()`/`find_library()` auto-detection methods.
Enabled by default for MSVC, outside vcpkg and when not cross-building.
To enable for other cases, or override the default, you can use
`-DCURL_USE_CMAKECONFIG=ON` or `OFF`.
When enabled, Config detection happens after `pkg-config` and before
`find_path()`/`find_library()`. Using CMake's built-in options, you may
also manually point to the absolute directory holding Config files:
`Libssh2_DIR`, `MbedTLS_DIR`, `NGHTTP2_DIR`, `NGHTTP3_DIR`,
`NGTCP2_DIR` v1.19.0+ (with non-fork OpenSSL only), `Zstd_DIR` v1.4.5+
E.g. `-DMbedTLS_DIR=/path/to/mbedtls/lib/cmake/MbedTLS`
These dependencies typically need to be built with CMake to support
this.
Tagged as experimental.
