Decklink: Fix crash when no matching device

Keyboard input wasn't working properly when using interact on Linux --
this should solve it.

OBS crashes when decklink output is auto started and the device is
removed or changed to different model while OBS is not running.

Fixes https://github.com/obsproject/obs-studio/issues/2494

On 10.15, if a user activates secure input of some sort, the hotkey code
will begin to crash inside of any Apple function related to hotkeys,
even after secure input has ended.  This does not appear to be the fault
of OBS; the reason to this is still as of yet unknown, but is suspected
to be a bug inside of Apple code that's a new regression as of 10.15.

So for the time being as a temporary solution to the crash, simply
disable external hotkey support once secure input has been detected.

Because of this issue, the hotkey code should probably be replaced by a
different method of tracking hotkeys, perhaps InstallEventHandler for
example.  This commit is little more than a bandaid to the crash.

Fix QuickSync LA_ICQ encoder settings

This fixes a hang on Ubuntu when closing the
dialogs after leaving them open for a time.

libobs-winrt: Stronger exception handling

obs-ffmpeg: Expose old NVENC on Windows 7

UI: Fix silent scenes with imported SL scenes

The bits were set in c0a8e86c, but they
are not needed.

New NVENC isn't available on Windows 7 and the old encoder was marked as
internal, giving users no option to use NVENC at all.

Signal only needs to be connected once, not every keystroke.

Also commit data only when text widget focus is lost to fix cursor
moving to the end of the string after every keystroke.

Exceptions were still leaking through somehow.

linux-v4l2: Fixup invalid id

Previous fix in #2547 altered id before they were handed off to
callbacks and v4l2 wont strip its own flags from ids resulting in
invalid ids in the ioctl.

Instead add cleanup section and jump all branches there before looping.

(Jim edit: I'm changing this entire function so that it isn't horrible.)

This will help identify devices sharing the same names (eg "Intel HD
Graphics") for potentially adding to the blacklists should they have
issues.

Version test macro was using the wrong version, and the non-crypto
MD5 only code was accidentally moved into an #ifdef which ended up
disabling it.

Fixes https://github.com/obsproject/obs-studio/issues/2426

Previously, the importer assumed scenes had fields that sources did for
audio, namely volume, sync, mute and monitoring type. SL scenes do not
have these fields. This resulted in mistakes in importing, such as
imported scenes having a volume of 0.0.

This change gets rid of the non-existent fields, and explicitly sets the
volume of the scenes to 1.0 as a precaution.

linux-v4l2: readonly controls cause infinite loop

v4l2_ioctl will clear the V4L2_CTRL_FLAG_NEXT_CTRL flag resulting in
infinite loops for any driver that reported readonly, disabled, or
volitile controls.

Before this change, opening up a fullscreen projector would have the
wrong window title (Windowed Projector). This was because the call to
update the window title was called before a monitor is set, and the
title is determined by whether a monitor is set.

This change moves the update title call to after the geometry or monitor
gets set, ensuring the window title is correct.
