Use `_TEXT()` when interacting with CRT functions (also prefer over
synonym `_T()`), `TEXT()` for Win32 functions.
Within curl, they mean the same because CRT/Win32 Unicode mode are
always enabled in sync.

The curl tool was creating a new transfer every time it checked if
it needed to add one to reach max parallelism. This led to eventually
all configured transfers to have easy handles created.
Limit the creation again to the ones needed for max parallelism.

The reason to use them seems to be that just (void) before a function
call is not enough to silence compiler warnings when return codes are
ignored and -Werror=unused-result is used.
While (void)! apparently works to silence those warnings, it is just too
weird and surprising to readers to use.
It is rather a reason to reconsider the usefulness of the warning.
Closes#22023
To contain the logic of checking for both `EWOULDBLOCK` and/or `EAGAIN`
depending on platform/availability. Also to avoid checking for both if
they mapp to the same value, and to avoid PP guards around use.
This also ensures `EAGAIN` is consistently not checked on Windows, where
headers defined it, but `SOCKERRNO` never returns it, because curl maps
it to `WSAGetLastError()`.
If they map to the same value, checking them both in an `if` expression
trips GCC warning `-Wlogical-op` (the same way it triggers duplicate
case value error in `switch`).
Also:
- replace two `switch()` statements with the new macro.
- tests/server/sws: make two outliers use the new macro that were only
checking for `EWOULDBLOCK` before this patch, in `connect_to()`.
- move variables to the left-side of expressions, where missing.
- rustls: use a variant of this macro that uses raw `EWOULDBLOCK`.
Tried tracing it back to the origins, but I couldn't figure out if
this is working as expected on all supported Windows versions in
Rust. It seems to be using `GetLastError()`, according to
https://docs.rs/system_error/0.2.0/system_error/, which would be
probably incorrect.
Notes:
- it's probably a good idea to assign `SOCKERRNO` to a variable before
passing it to this macro.

Also:
- bump AmiSSL to the latest release.
- add download hash checks and toolchain cache.
- sync restored code with local updates made since last year.

Adjust code to avoid `-Wformat-signedness` warnings, while making sure
that enums are always cast to a known type when passing them to `printf`
functions, to support compilers and compiler settings where enums are
not default-size signed ints.
- cast integers printed as hex to `unsigned`. (63 times, 20 of them in
`mbedtls.c`)
- cast misc enums to `int` for printing. (31 times)
- cast `CURL_LOCK_DATA_*` enums to `int`. (4 times)
- cast `CURL_FORMADD_*` enums to `int`. (13 times)
- cast `CURLSHE_*` enums to `int`. (3 times)
- cast `CURLUE_*` enums to `int`. (33 times)
- cast `CURLMSG_*` enums to `int`. (6 times)
- cast `CURLE_*` enums to `int`. (~380 times)

Add test_31_13 to check connection reuse on mixed --ssl-reqd setting.
For that add debug env var CURL_DBG_NO_USE_SSL_ON_FIRST to disable
--ssl-reqd for the first url. Check that the connection without SSL
from the first url is not reused on the second URL that requires it.
Tweak special ftp: protocol check to fail a DEBUGASSERT on mismatched
`use_ssl` settings as that should have been caught before in the
connection reuse matching (imap/smtp etc. do not have this extra check
and rely on the general part doing its job).

Closes#21772
This patch adds two major proxy capabilities to curl (ngtcp2 QUIC):
- HTTP/3 Proxy CONNECT: Tunnel HTTP/1.1 or HTTP/2 traffic through an
HTTPS proxy that speaks HTTP/3 (QUIC) using the standard CONNECT
method over an HTTP/3 connection.
- MASQUE CONNECT-UDP: Tunnel HTTP/3 (QUIC) traffic through an HTTP
proxy (speaking HTTP/1.1, HTTP/2, or HTTP/3) using the extended
CONNECT method with the CONNECT-UDP protocol (RFC9297 & RFC9298).
Public API additions:
- `CURLPROXY_HTTPS3`: new proxy type constant for HTTP/3 proxy
- `--proxy-http3`: new CLI flag to negotiate HTTP/3 with HTTPS proxy
The implementation adds two new filters:
- `H3-PROXY` - enables negotiating HTTP/3 (QUIC) to the proxy and
running CONNECT/CONNECT-UDP through that proxy transport.
- `CAPSULE` - dedicated filter inserted between QUIC transport and
HTTP-PROXY to handle datagram capsule encapsulation/decapsulation.
Here is how the curl filter chaining looks in different scenarios:
- HTTP/3 Proxy CONNECT (tunneling TCP protocols over QUIC proxy):
conn -> HTTP/1.1 or HTTP/2 -> SSL -> HTTP-PROXY ->
H3-PROXY -> HAPPY-EYEBALLS -> UDP
- MASQUE CONNECT-UDP (tunneling QUIC over any proxy):
conn -> HTTP/3 -> CAPSULE -> HTTP-PROXY -> H3-PROXY ->
HAPPY-EYEBALLS -> UDP
conn -> HTTP/3 -> CAPSULE -> HTTP-PROXY -> H1-PROXY or H2-PROXY ->
SSL -> HAPPY-EYEBALLS -> TCP
- Both features currently require the ngtcp2 QUIC backend.
- Both features are experimental (disabled by default). Enable with
`--enable-proxy-http3`(autotools) or `-DUSE_PROXY_HTTP3=ON`(CMake).
Tests:
- tests/unit/unit3400.c: Unit tests for capsule protocol encode/decode
- tests/http/test_60_h3_proxy.py: Comprehensive pytest integration suite
- tests/http/testenv/h2o.py: Managing h2o instances with HTTP/1.1, HTTP/2,
and HTTP/3 (QUIC) listeners, proxy.connect and proxy.connect-udp enabled.

Use parts of text from the upload filename field when that uses globbing
by giving it a name the same way we do it for URL globs. For example, if
