and thus enable support for:
 - colour console logging.
 - colour help text.
 - colour highlighting of errors and warnings when parsing commandline
   arguments on windows.

according to [1] microsoft provide `isatty()` support under the name
`_isatty()` in `io.h` due to it being non-standard.

i was originally going to attempt to duplicate the use of the
`GetConsoleMode()` function as done in the rust `atty` crate, but the
existence of `_isatty()` is much more simple. it's left me confused over
why the rust crate uses `GetConsoleMode()` instead. i have not turned up
any info so far about when `_isatty()` was introduced on windows, so maybe
its too new? maybe it doesn't support special environments like cygwin? i
have noted that it was already in use by `src/text/unicode.c`.

In the case where compositor fails to start the MediaLib object is created then
destroyed using a deleteLater, but the destructor was never called as the main
loop was never started.

When overriding the environment variable, we might cause a pkg-config
wrapper to skip setting its environment variable when cross compiling.
By providing an empty string, we'd effectively disable detection of all
available packages in a non-default path.

fix: #26462

AVCodecContext.thread_safe_callbacks will be removed in API 60:

> Thread-unsafe get_buffer2() implementations will be invalid starting
> with LIBAVCODEC_VERSION_MAJOR=60; in other words, libavcodec will
> behave as if this field was always set to 1.

In current FFmpeg 5.0 (API 59), we must still set the variable, and it
is already deprecated, so we can't get rid of the deprecation warning.

with cats and subcats both being plain integers it's very easy to
make a mistake mixing them up, storing one in a variable for another,
or passing the wrong variable to the wrong function.

switching to enums adds type strictness to help catch such mistakes.

in switching to enums there is of course additional opportunity to
exploit sequential numbering to achieve certain optimisations that
can be gained from this, but that it not done here. here we're simply
interested in catching mistakes through type strictness.

note that we simply retain the same cat/subcat numbering as before
here.

This unbreaks packages using autoreconf.

Lousy implementation since snd_pcm doesn't provide non blocking drain
API.

"amem-drain" is still synchronous, the drained state is reported after
the call to this blocking callback.

Thomas Guillem authored 3 years ago and Rémi Denis-Courmont committed 3 years ago

aout_DecDrain() is now asynchronous, except for modules still implementing
aout->drain (only during the transition).

Add aout->drain_async(). Aout modules should implement drain_async
instead of drain, and call aout_DrainedReport() to report that the
stream is drained.

Aout modules not implementing any drain functions will still rely on
aout_TimeGet() to detect the end of the stream.

MFCreateDXGIDeviceManager is only available on Win8+ so we bring back the DLL loading.

The decoder may need to be released with the last picture.

In case there is more than one we should not read all of them each time.

This is currently a buffer we provide so it should not happen.

We may not really need it at all though and it's supposed to degrade quality.

CODECAPI_AVLowLatencyMode is not always defined.

This way we can always check we're in the proper state to do it.

No functional changes.

So we don't need to check for S_OK after.

Plus hr is modified afterwards and may end up in the code that was supposed to
be for this specific call.

Requires to use decoder_sys_t as an object.
