In the current user interface code, OBSBasic::AddSceneCollection has a
qname parameter to allow explicitly specifying a name, but that code
path is unused in the UI code itself, and qname is typically empty.  If
qname is not empty, it does not properly generate a file name associated
with that specified scene collection name.  This fixes that issue.

libobs: add missing FreeBSD #include to fix build

sysctlbyname requires #include <sys/sysctl.h>.  Perhaps this previously
worked due to header pollution that has since been cleaned up in newer
FreeBSD.

libobs: fix building modules once installed

sse-intrin.h is a required header now, but the implicit path
breaks building addons once the headers are installed.

Fix this by making the path explicit.

Helps prevent accidental stream starting if for example a cat walks on
the spacebar while the button has focus.

Enable Aarch64 support via SIMDe

This fixes an issue where local files were using the avformat interrupt
callback, which is only supposed to be use to prevent blocking on
network calls.

The interrupt callback is designed to prevent the media source from
blocking; FFmpeg will internally call it periodically to prevent FFmpeg
function calls from blocking too long, and allow the caller to determine
whether blocking should stop.

The problem with this however is that AVERROR_EXIT causes the thread to
completely exit.  This fixes it so that it treats it as an EOF rather
than as an abnormal error.

CI: Keep artifacts for PRs labelled "Seeking Testers"

Add arch checks to enable aarch-compat layer on aarch64, retain normal
gcc intrinsics on x86 and ppc64.

Add a compatibility layer utilizing simde
(https://github.com/nemequ/simde) to allow compilation on aarch64
without modifying existing functions.

Only print the first message for this known benign error.

Clean up COM initialization

Qt seems to force STA, so it's misleading to ask for MTA and ignore the
failure result, so just ask for STA. Also, don't uninitialize COM if
initialization failed.
