Previously, after PASV and immediately after the data connection has
connected, the function would only return the control socket to wait for
which then made the data connection simply timeout and not get polled
correctly. This become obvious when running test 1631 and 1632 event-
based.
Use them only if `_UNICODE` is defined, in which case command-line
arguments have been converted to UTF-8.
Closes https://github.com/curl/curl/pull/3784
- use `wmain` instead of `main` when `_UNICODE` is defined [0]
- define `argv_item_t` as `wchar_t *` in this case
- use the curl_multibyte gear to convert the command-line arguments to
UTF-8
This makes it possible to pass parameters with characters outside of
the current locale on Windows, which is required for some tests, e.g.
the IDN tests. Out of the box, this currently only works with the
Visual Studio project files, which default to Unicode, and winbuild
with the `ENABLE_UNICODE` option.

Closes https://github.com/curl/curl/pull/3784
Fix theoretical integer overflow in Curl_auth_create_plain_message.
The security impact of the overflow was discussed on hackerone. We
agreed this is more of a theoretical vulnerability, as the integer
overflow would only be triggerable on systems using 32-bits size_t with
over 4GB of available memory space for the process.
Closes#5391
Since input passed to libcurl with CURLOPT_USERPWD and
CURLOPT_PROXYUSERPWD circumvents the regular string length check we have
in Curl_setstropt(), the input length limit is enforced in
Curl_parse_login_details too, separately.

Closes#5383
When looking for a protocol match among supported schemes, check the
most "popular" schemes first. It has zero functionality difference and
for all practical purposes a speed difference will not be measureable
but it still think it makes sense to put the least likely matches last.
"Popularity" based on the 2019 user survey.
Closes#5377
Add three new CMake Find modules (using the curl license, but I grant
others the right to apply the CMake BSD license instead).
This CMake config is simpler than the autotools one because it assumes
ngtcp2 and nghttp3 to be used together. Another difference is that this
CMake config checks whether QUIC is actually supported by the TLS
library (patched OpenSSL or boringssl) since this can be a common
configuration mistake that could result in build errors later.
Unlike autotools, CMake does not warn you that the features are
experimental. The user is supposed to already know that and read the
documentation. It requires a very special build environment anyway.
Tested with ngtcp2+OpenSSL+nghttp3 and quiche+boringssl, both built from
current git master. Use `LD_DEBUG=files src/curl |& grep need` to figure
out which features (libldap-2.4, libssh2) to disable due to conflicts
with boringssl.
Closes#5359
If the QLOGDIR environment variable is set, enable qlogging.
... and create Curl_qlogdir() in the new generic vquic/vquic.c file for
QUIC functions that are backend independent.

That return code is reserved for build-time conditional code not being

Triggered by a crash detected by OSS-Fuzz after the dynbuf introduction in
ed35d6590e. This should make the trailer handling more straight forward and
hopefully less error-prone.
Deliver the trailer header to the callback already at receive-time. No
longer caches the trailers to get delivered at end of stream.

In my very basic test that lists sftp://127.0.0.1/tmp/, this patched
code makes 161 allocations compared to 194 in git master. A 17%
reduction.
Closes#5336
quiche has the potential to log qlog files. To enable this, you must
build quiche with the qlog feature enabled `cargo build --features
qlog`. curl then passes a file descriptor to quiche, which takes
ownership of the file. The FD transfer only works on UNIX.
The convention is to enable logging when the QLOGDIR environment is
set. This should be a path to a folder where files are written with the
naming template <SCID>.qlog.

Replaces #5337Closes#5341
A common set of functions instead of many separate implementations for
creating buffers that can grow when appending data to them. Existing
functionality has been ported over.
In my early basic testing, the total number of allocations seem at
roughly the same amount as before, possibly a few less.
See docs/DYNBUF.md for a description of the API.
Closes#5300
- Check for NULL entry parameter before attempting to deref entry in
Curl_resolver_is_resolved, like is already done in asyn-ares.
This is to silence cppcheck which does not seem to understand that
asyn-ares and asyn-thread have separate Curl_resolver_is_resolved
and those units are mutually exclusive. Prior to this change it warned
of a scenario where asyn-thread's Curl_resolver_is_resolved is called
with a NULL entry from asyn-ares, but that couldn't happen.

More connection cache accesses are protected by locks.
CONNCACHE_* is a beter prefix for the connection cache lock macros.
Curl_attach_connnection: now called as soon as there's a connection
struct available and before the connection is added to the connection
cache.
Curl_disconnect: now assumes that the connection is already removed from
the connection cache.

Regression since 7.69.0 and 68fb25fa3f.
The code wrongly assigned 'from' instead of 'auth' which probably was a
copy and paste mistake from other code, leading to that auth could
remain NULL and later cause an error to be returned.

Previously, options set explicitly through command line options could be
overridden by the configuration files parsed automatically when
ssh_connect() was called.
By calling ssh_options_parse_config() explicitly, the configuration
files are parsed before setting the options, avoiding the options
override. Once the configuration files are parsed, the automatic
configuration parsing is not executed.

Prior to this change if there was a 303 reply to a PUT request then
the subsequent request to respond to that redirect would also be a PUT.
It was determined that was most likely incorrect based on the language
of the RFCs. Basically 303 means "see other" resource, which implies it
is most likely not the same resource, therefore we should not try to PUT
to that different resource.
Refer to the discussions in #5237 and #5248 for more information.
