Connection filters had a method `get_host()` which had not really been
documented. Since then, the cf had the `query()` method added. Replace
the separate get_host with query.
Add `CF_QUERY_HOST_PORT` as query to connection filters to retrieve
which remote hostname and port the filter (or its sub-filter) is talking
to. The query is implemented by HTTP and SOCKS filters, all others pass
it through.
Add `Curl_conn_get_current_host()` to retrieve the remote host and port
for a connection. During connect, this will return the host the
connection is talking to right now. Before/After connect, this will
return `conn->host.name`.
This is used by SASL authentication.
Closes#17419
Add a bitset `dirty` to the multi handle. The presence of a transfer int
he "dirty" set means: this transfer has something to do ASAP.
"dirty" is set by multiplexing protocols like HTTP/2 and 3 when
encountering response data for another transfer than the current one.
"dirty" is set by protocols that want to be called.
Implementation:
* just an additional `uint_bset` in the multi handle
* `Curl_multi_mark_dirty()` to add a transfer to the dirty set.
* `multi_runsingle()` clears the dirty bit of the transfer at
start. Without new dirty marks, this empties the set after
al dirty transfers have been run.
* `multi_timeout()` immediately gives the current time and
timeout_ms == 0 when dirty transfers are present.
* multi_event: marks all transfers tracked for a socket as dirty.
Then marks all expired transfers as dirty. Then it runs
all dirty transfers.
With this mechanism:
* Most uses of `EXPIRE_RUN_NOW` are replaced by `Curl_multi_mark_dirty()`
* `Curl_multi_mark_dirty()` is cheaper than querying if a transfer is
already dirty or set for timeout. There is no need to check, just do it.
* `data->state.select_bits` is eliminated. We need no longer to
simulate a poll event to make a transfer run.

Implements a seperate read thread for STDIN on Windows when curl is run
with -T/--upload-file .
This uses a similar technique to the nmap/ncat project, spawning a
seperate thread which creates a loop-back bound socket, sending STDIN
into this socket, and reading from the other end of said TCP socket in a
non-blocking way in the rest of curl.

In the unlikely case that no SSH auth methods are supported, the
previous code would return 0 from myssh_in_AUTH_PKEY_INIT. However,
following the code path, it seems like it should be returning SSH_ERROR,
as set in myssh_to_ERROR (through myssh_to_GSSAPI_AUTH,
myssh_to_KEY_AUTH and myssh_to_PASSWD_AUTH).
In actuality, this is unlikely to occur, as the similar code in
myssh_in_AUTHLIST would have already returned an error in this scenario.
However setting a return value and then ignoring it is a bit fishy and
should be documented if this is intended.
I believe this used to return an error, but was changed in the recent
re-factoring of this code.
Closes#17691
Derive it from `$BUNDLE` instead. autotools seems to be already relying
on `$BUNDLE_SRC` being equal to `$BUNDLE.c`. (I haven't realized this
before aaebb45f58b3f62876a68c17c71ac37d98f1b3bb.)
Also drop redundant `nodist_<target>_SOURCE` lines in tunits and units.

Used by test 2056 and 2057, in a way that's Linux- & autotools-specific.
This patch builds it for all Unix, syncing cmake with autotools.
Adapt the two tests to find the library in CMake builds as well.
Tested OK on Linux. (CI does not test this. The corresponding jobs build
in debug mode, while the `LD_PRELOAD` feature is locked to non-debug.)
On macOS it didn't load without building everything for aarch64e arch:
"../bld/tests/libtest/libstubgss.dylib' (mach-o file, but is
an incompatible architecture (have 'arm64', need 'arm64e'))"
With that fixed it still did not load correctly and/or the tests did not
pass. So, for macOS these tests remain disabled.
Also:
- GHA/macos: build for aarch64e. (recognized by Apple clang as of this
patch. llvm and gcc fall back to aarch64.)

Background:
As part of my work on reproducible builds for openSUSE, I check that
software still gives identical build results in the future. The usual
offset is +16 years, because that is how long I expect some software
will be used in some places. This showed up failing tests in our package
build. See https://reproducible-builds.org/ for why this matters.
I tested that it passes on x86_64 in year 2041 and i586 in year 2037.
(but on i586, I got `TESTFAIL: These test cases failed: 31 46 61 1415`)
Closes#17665
The `#undef` hack is no longer necessary after changing the redifitions
to not map back to the original symbols.
This makes it unnecessary to repeat the redefinitions after compiling
`warnless.c` itself (in unity mode).
Which in turns makes it unnecessary to include `warnless.h` again, to
trigger such redefinition.
This also means that `read`/`write` are now redefined on Windows from
the first inclusion of `warnless.h`.
Also:
- tests/server: drop a repeat `warnless.h` include, that is unnecessary
after this patch.
- tests/unit: drop repeat `warnless.h` include.
- tests/libtest: drop repeat `warnless.h` includes.
- tests/libtest: formatting.

Use it from libtests' `first.c` and thus also from units, and tunits.
Also:
- cmake: drop stray `curltool` lib dependency for units.
- units: stop depending on `src` headers.
- tests/server: drop depending on `src` headers.
(the remaining one listed in the comments, `tool_xattr.h`, was not
actually used from servers.)
- tests/server: drop duplicate curlx headers.
(Except `warnless.h`, which is tricky on Windows.)

To pass `-municode` to the linker. Before this patch we passed this via
`target_link_libraries()` which is designed to pass libraries. Keep
using it for old CMake versions, where no better alternative existed.
https://cmake.org/cmake/help/latest/command/target_link_options.html
Also:
- also pass `-municode` as `PRIVATE` for old cmake versions.
(it should not make a difference because no target depends on the curl
tool, but this seem to be the modern, non-ambiguous syntax.)
- unfold a bunch of split lines for greppability of `add_library()` and
`add_executable()` commands.
- quote a string.

To reduce the diff between tests CMakeFiles.txt, and syncing with
autotools, which already used the `BUNDLE` variable like this.

- GHA/windows: make a mingw autotools build static only.
- GHA/windows: fix a CI script issue with the build above.
- src: fix to pass `LIBCURL_PC_LIBS_PRIVATE` instead of `LINKFLAGS`.
This makes the libs propagate to tunits, making the local hack there
unnecessary. `LINKFLAGS` had this single use in the repo, and it was
empty in local tests.
- tests: drop passing redundant `LIBCURL_PC_LDFLAGS_PRIVATE`.
- tests: drop redundant target name from config variables.
- examples, tests/client: drop `LIBDIR` temp variables with single uses.
- examples, tests: formatting to sync `Makefile.am` scripts with each
other.
