This solves the issue of users who close the primary dock widgets and
can't figure out how to get them back, who for whatever reason choose
not to read the message box when closing dock widgets that tells them
how to get it back.  The users can still hide the primary dock widgets
via the View menu, but they can no longer close them via the [x] button
on the dock widget.  This change does not apply to secondary dock
widgets, such as a chat window, stats, etc.

This also modifies libobs.

This only happened on Linux.

Fixes https://obsproject.com/mantis/view.php?id=1018

This fixes a seg fault that would happen when launching OBS from the
terminal and then hitting ctrl-c.

In commit a776a6cf, the image_file_t structure (which is a public
structure) had a member variable added to it, which broke ABI.

While performing a release candidate, it is important to use an actual
version before the actual release candidate version so that the
auto-updater will know to update to 23.1.0

UI: Remove help icon from source select dialog

Fixes https://obsproject.com/mantis/view.php?id=1394

Fixes a crash that can happen if you try to use the settings window
while in an even subloop, or if you try to close OBS while in an event
subloop.  Continually retries (defers) the actions every one second
until the subloop has finished.

obs-filters: Remove unused function in shader

libobs: Fix Area scale filter for GLSL

libobs: Remove dead code in sharpness effect

The quadro P5000 would incorrectly be considered blacklisted because it
used a string search for the P500, which is an earlier quadro variant
that does not have NVENC support.

To fix this, instead of just doing a string search, additionally check
to make sure that there preceding or trailing numbers on the adapter
name.

Closes obsproject/obs-studio#1768

Not sure why, but there's a dead uniform and interpolant in the
sharpness effect. This change removes them.

SampleYUVToRGB() is no longer used after the previous DrawMatrix purge.

Remove const qualifiers because they are syntax errors for GLSL when
used like in C.

Without this, Fork and PR builds will fail.

OBS_EFFECT_AREA from 7d811499 was inserted in the middle of the enum,
which breaks ABI for any binaries that use
OBS_EFFECT_PREMULTIPLIED_ALPHA or OBS_EFFECT_BILINEAR_LOWRES.
