For some reason librtmp treats a close message as a request to reconnect.
It does this syncronously, and uses the same event processing so that
another close request will continue the cycle until the stack is exhausted
and the application crashes.

It was unintentionally using intra-only before, impacting quality.

Twitch no longer recommend Main profile on their "Broadcast requirements"
page. The number of devices that can't decode High profile is very small
and limited to old, legacy devices such as the 1st generation iPad (six
years old). Additionally, these devices have limited resolution / FPS
support, so streams are often encoded at levels beyond what they could
decode even disregarding the H264 profile requirement. It's not worth
degrading the quality of streams for modern devices just to support these
legacy decoders. Twitch still provides low-complexity transcodes for
devices which cannot handle Source quality streams.

A linker error for XGetXCBConnection started occurring after the
frontend API was added, the fix is simply to make sure libobs is
properly linking to X11_XCB.

libobs: Add downscale filter to log

obs-text: Add bk color/opacity properties

When a pulseaudio source is created from existing settings and the
device is not found, then the private data will return NULL, making it
impossible to change the source to use a different device.  NULL should
never be returned when possible, otherwise settings cannot be changed
and properties cannot be displayed.

The maximum shutdown timeout value was added as a setting, but never
actually fully implemented.  This implements it properly, and sets its
default timeout value to 30 seconds.

Fixes a crash that could happen where you close the window while the
main window is hiding, and then the app mistakenly thinks that "all
windows are closed" and initiates shutdown while the main window is
still active but hidden.

Fixes a bug where you could minimize to tray if the settings window was
open.

UI: Fix crash in filters dialog caused by access to deleted widget

This reverts commit 4b0f22d0.

Services should not force tunes.

Sometimes the revision number isn't put in to the kernel32.dll version
information.  It's best to use the registry in this case.

The profile setting may have been unintentionally removed in 0157d025.

Rather than reload when the timestamp is greater than the previous
timestamp, reload whenever the timestamp has changed.

image-source: Reload file when timestamp has changed

The call type for the deleter function used with the GDIObj helper class
is __stdcall.  Without it, it'll fail to build in 32bit properly.

This reverts commit 7224e8d3.

This change was unnecessary due to the fact that indexing is already
performed automatically via the cast operator.
