Before this patch the internal feature detection macro
`HAS_MBEDTLS_RESULT_CODE_BASED_FUNCTIONS` was defined in three files,
with an incomplete logic in one of them. In Unity mode that spilled
into another source file and broke the build.
Closes#13377
Since we can go to the CONNECT state from PENDING, potentially multiple
times for a single transfer, this change introdues a SETUP state that
happens before CONNECT when doing a new transfer.
Now, doing a redirect on a handle goes back to SETUP (not CONNECT like
before) and we initilize the connect timeout etc in SETUP. Previously,
we would do it in CONNECT but that would make it unreliable in cases
where a transfer goes in and out between CONNECT and PENDING multiple
times.
SETUP is transient, so the handle never actually stays in that state.
Additionally: take care of timeouts of PENDING transfers in
curl_multi_perform()
Ref: #13227Closes#13371
When there is a "change" in a multi handle and pending handles are moved
back to the main list to be retested if they can proceed further (for
example a previous transfer completed or a connection has a confirmed
multiplexed state), the timeout check in multi_runsingle() would not
trigger because it required an established connection.
This could make a pending tranfer go back to pending state even though
it had been "in progress" for a longer time than permitted. By removing
the requirement for an associated connection, the timeout check will be
done proper even for transfers that has not yet been assigned one.

Closes#13276
OS/400 ascii fputc wrapper deviates from the posix standard by the
fact that it returns the ebcdic encoding of the original ascii
character. Testing for a matching value for success will then always
fail.
This commit replaces the chariacter comparison by an explicit error
return check.

Before this patch `lib/curl_setup.h` defined these two macros right
next to each other, then the source code used them interchangeably.
After this patch, `USE_HTTP3` guards all HTTP/3 / QUIC features.
(Like `USE_HTTP2` does for HTTP/2.) `ENABLE_QUIC` is no longer used.
This patch doesn't change the way HTTP/3 is enabled via autotools
or CMake. Builders who enabled HTTP/3 manually by defining both of
these macros via `CPPFLAGS` can now delete `-DENABLE_QUIC`.
Closes#13352
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.
Closes#13349

Tests were consistently flaky for a while.
Also fix compiler warnings in `CertOpenStore()` calls for old MSVC compilers:

- When the writing of response data fails, reset the stream
and do not return a callback error to nghttp2. That would
be a fatal error for the connection and harm other requests.

Fixes#13292Closes#13298
Since mbedTLS v3.6.0, the RNG check added in ssl_conf_check() will fail
if no RNG is provided when calling mbedtls_ssl_setup().
Therefore, mbedtls_ssl_conf_rng() needs to be called before the SSL
context is passed to mbedtls_ssl_setup().

Closes#13314
- add curl_int64_t signed 64-bit type for lib use
- define CURL_PRId64, CURL_PRIu64 format ids
- use curl_int64_t in vquic
curl_int64_t signed complements the existing curl_uint64_t unsigned.
Note that `curl_int64_t` and `int64_t` are assignable from each other
but not identical. Some platforms with 64 long type defint int64_t as
"long long" (staring at macOS) which messes up things like pointers and
format identifiers.

- Use data->multi and not data->multi_easy to refer to the active multi.
The easy handle's active multi is always data->multi.
This is a follow up to 757dfdf which changed curl so that an easy handle
used with the easy interface and then multi interface cannot have two
different multi handles associated with it at the same time
(data->multi_easy from the easy interface and data->multi from the multi
interface).

Closes#13272
- when an application forces HTTP/1.1 chunked transfer encoding
by setting the corresponding header and instructs curl to use
the CURLOPT_READFUNCTION, disregard any POST length information.
- this establishes backward compatibility with previous curl versions
Applications are encouraged to not force "chunked", but rather
set length information for a POST. By setting -1, curl will
auto-select chunked on HTTP/1.1 and work properly on other HTTP
versions.

- curl's transfer handling may write 0-length chunks at the end of the
download with an EOS flag. (HTTP/2 does this commonly)
