This commit adds functions to get, set and save the service and its
settings, and is plugged straight into the existing internal functions
serving this purpose

(Jim: Fixed commit message and missing newline at end of file)

Closes jp9000/obs-studio#895

Changes "class" prioritization to attempt to find the window either with
the same title, or the next window of the same window class (window
type), changes "title" prioritization to only find the window based
upon its title, and changes "executable" prioritization to attempt to
find the window with the same title, or the next window of the same
executable.

Additionally changes the text associated with these selections to
clarify that functionality to users.

UI: Remove unused defines from old updater code

This commit removes some define statements that were used in the updater
code before OBS Studio 18.0.0.

Fix various typos across multiple modules

libobs-opengl: Log OpenGL version on all systems

This commit logs the OpenGL version on all operating systems and brings
the OpenGL subsystem's initialization logging more in line with the
D3D11 logging to make logs more uniform.

Now that OBS defaults to 64 bits on Windows, our crash reports are often
truncated since the 64 bit stack values are using twice as much space.

Otherwise the user can't actually switch back to Direct3D since the
settings panel doesn't consider the renderer to be modified.

OpenGL on Windows is rather unstable and can result in graphical
corruption or the complete inability to start OBS since some GPUs do not
support the minimum requirements after switching to OpenGL. The UI option
is now hidden unless --allow-opengl is passed on the command line.

The D3D adapter is currently unused and we often find users are concerned
when their GPU does not appear in the list.

UI: Add window name to remux dialog

win-dshow: Fix reallocation issue in ffmpeg-decode

Use reStructuredText to allow HTML formatting while still maintaining
clarity in the raw text.

rtmp-services: Update Picarto maximum bitrates

(Note: This commits also modifies the linux-pulseaudio, mac-capture, and
win-wasapi plugins)

Do not prevent the targeted output device from being monitored if the
selected monitor output device is a different one.

libobs: Remove multiple calls to free_type_data

This happens because the enum had the incorrect name, and microsoft
automatically treats all enums as integers in C, regardless of whether
they actually exist or not.  Microsoft makes terrible compilers and
whoever decided this was a good idea should be fired.

Just directly includes the ff-util.c/h files in to UI to prevent the
need of compiling libff in full.

Isn't really necessary due to libff being deprecated

Intended to replace libff as the media playback library.  Intended to
use less threads and be more extensible.  It was nearly impossible to
modify libff without bursting a vein.

Prevents any delay when starting up certain async video sources.
Additionally prevents old frames from being presented as well.

This change prevents source flags from being incorrectly overwritten and
set to 0.  Eventually flags need to be separated from source settings
and this should be reverted, but for now this solves an issue where
buffering would be enabled on async video sources regardless of whether
the user disabled it or not on the source.

Delay the "audio stopped" detection by one audio tick to ensure that
audio doesn't get intentionally cut out in some situations

Update maximum video bitrate for Picarto from 2000 to 3500 and maximum
audio bitrate from 160 to 128.

When the windows video device source source is set to only activate when
showing, it would still activate on first startup of the program even if
it was in another scene and not showing anywhere to the user.  This
fixes that issue.
