The frontend API event OBS_FRONTEND_EVENT_REPLAY_BUFFER_SAVED was not
being triggered when hotkeys were used because it was only set to
trigger when the replay buffer button was clicked, not when a hotkey was
used. This fixes it so that the frontend event sends a signal to the
frontend so that hotkeys will actually work.

New events must go at the bottom of the list, not at the top, otherwise
ABI will be broken.

Docs: Fix Frontend Finish Loading event

Fixes obsproject/obs-studio#3465

When deleting a transition, it would sometimes select the one that
replaces it, which could be the separator.  This would cause undefined
behavior.  This fixes it so that it selects either the one that replaces
it (if a valid one replaces it), or the transition at the bottom of the
known list and not the separator.

Apparently using LoadLibrary on a full path doesn't work -- you need to
use SetDllDirectory before loading a library.

The path of coreaudio dll has changed in current versions of iTunes on
windows.  The patch fixes the issue while keeping compatibility with
previous path.

Fixes obsproject/obs-studio#3503

Refactors the windows import library section so that it uses a list, and
remove a slightly unnecessary macro in release_lib

This reverts commit 01fe9c99.

EVGA/magewell devices seem to use the default system drivers rather than
custom drivers, which causes their audio to become decoupled and treated
as completely separate devices rather than as an audio pin on the video
device. Basically, this would cause those devices to not have audio by
default, and force the user to have to manually select the audio, which
is bad user experience.

We already had a workaround for this with elgato devices, so expand that
code to become a whitelist of devices, and include EVGA/magewell
devices.

We were performing a custom cursor draw for WGC, which we attempted
because we thought we could bring back hardware cursor responsiveness,
but MS says that it won't. Since the custom draw was bugged to cause
black screens anyway, just use the native cursor draw for now.

Rivatuner Statistics Server calls vkGetInstanceProcAddr for
vkCreateDevice with a NULL instance. According to spec, this should
return NULL, but RTSS will dereference this and crash.

This change returns function pointers for every intercepted function
regardless of instance, which is enough to keep RTSS alive.

ffmpeg-mux does not notice if ffmpeg returns an error from
av_interleaved_write_frame() which means that OBS never knows if there is a
problem in ffmpeg.

This is the biggest issue for cases like srt:// or tcp:// streams that can
regularly fail. Without this change OBS never knows that something went wrong.

If using ffmpeg-mux to send a network stream, signal a disconnect error code
on error to allow reconnections to take place.

The VolumeMeter widgets were apparently being drawn as transparent
widgets, which meant that it was necessary to redraw everything under
the widgets in order to properly draw the widgets, so the entire mixer
section of the window was being redrawn every time the meters updated.
This caused a significant perf hit when the only thing wanted/desired
was just to update the meters. This was more noticeable after changing
the audio meter update rate to 60hz from 30hz.

The fix is to simply mark them as opaque widgets, and paint the
background ourselves rather than rely on what's under the window. CPU
perf for painting the main window has been vastly improved because of
this; CPU usage of Qt in the main window is now reduced by at least half
of what it was, if not more.

FreeBSD removed the swig30 package and replaced it with just swig,
currently version 4.0:

A generally accepted path for DepsPath or LibfdkPath is the parent
directory that includes the 'bin' and 'include' directories. This fix
ensures FindLibfdk.cmake acts like other cmake helper scripts.

Closes obsproject/obs-studio#3474

Remove weabook.live from services.json

It seems like weabook.live is no longer a live streaming provider.

As with Windows and macOS there's no need to check for ChromeOS on
FreeBSD.
