XDG Portals provide a plethora of features meant to be used inside and
outside sandboxed environments. OBS Studio currently uses portals to
implement Wayland-compatible monitor and window captures.
However, OBS Studio performs another action that can be done through
portals: inhibit the screensaver. Under the Desktop portal (the same
used by the captures mentioned above), there is an "Inhibit" portal
that provides session inhibition.
Add a new portal-based inhibitor. This inhibitor is only used when the
Desktop portal is available and running; the previous D-Bus implementation
is used in the absence of the portal. Because it's basically another set
of D-Bus operations, wrap the new portal inhibitor under the HAVE_DBUS
call too.
macOS should use the function clock_gettime_nsec_np() to get the
current clock in nanoseconds, instead of manually using
mach_absolute_time() and manually adjusting the timebase. This
greatly simplifies the platform-specific code to manage the
current time in nanoseconds.
When calling D-Bus methods, three fields are required:
* The bus name, which is what applications own when they
want to expose themselves to D-Bus;
* The object path, which represents a D-Bus object exported
under a bus name;
* The interface, which holds the methods and signals;
While out of pure coincidence all the D-Bus buses have a
matching interface name, it is technically incorrect to assume
that.
Add a new 'interface' field to service_info, and split the bus
name.
GDBus is more and better maintained than libdbus these days. In the
future, a potential Wayland-compatible capture plugin will need to
interact with D-Bus in a way that's way too complicated for libdbus,
and it won't be nice to have both libraries talking to the D-Bus
socket.
Replace the libdbus usage by GDBus. As it turns out, it results in less
code.
Add exchange functions to alias the poorly named set functions.
Add store without reading previous. Faster on non-x86 processors.
Add compare-exchange that updates previous to avoid redundant fetch.
On Windows, load bool without conversion from char.
On Windows, load using mov with compiler barrier. Still seq_cst.
On POSIX, use GCC __atomic builtins.
This function determines if something is an OBS plugin before attempting
to load it. On Windows, many plugins ship their dependent DLLs alongside
the plugin DLL, so OBS would load things like libcef.dll on startup only
to immediately free it. For other platforms, this is less of a concern
so this function is a no-op for now.
This improves startup time and reduces risk from dependent DLLs
potentially running code with unwanted side effects in DllMain.

Simplify usage of the SIMDe header
This obviates the need for sse2neon as well and fixes compilation of all
plugins that referenced sse-intrin.h on all architectures, not just
arm*.
Adds a cmake variable (DEBUG_FFMPEG_MUX) which enables FFmpeg debug
output in the ffmpeg-mux subprocess, and if on Windows, shows the
console window of the ffmpeg-mux subprocess so the current output can be
seen.
It is undefined behavior to apply an offset to a null pointer. I would
have liked to reference cppreference but best I found was the PR that
added this check to clang's undefined behavior sanitizer:
https://reviews.llvm.org/D67122 .
As os_gettime_ns() gets large the current scaling methods, mostly by casting
to uint64_t, may lead to numerical overflows. Sweep the code and use
util_mul_div64() where applicable.

Instead of erroring out completely when it can't determine if the
certificate is valid, proceed anyway. This matches how web browsers
treat failed cert revocation checks. schannel just has somewhat
paranoid defaults.
os_readdir might return an empty path if the OS filename doesn't fit
into the buffer after os_wcs_to_utf8. If this empty path is then passed
to os_get_path_extension it causes a crash.
Previously, any short write would be treated elsewhere as a failure. The
easiest solution is to have pipe_write() automatically retry until either
it's written everything, or it couldn't write anything at all.
A plugin that saves whitespace-only data would crash OBS on startup as
the whitespace stripping would send the string length negative. While
that bug is fixed in this commit, there is also no good reason that OBS
is stripping whitespace to begin with. All data going into the configs
should be well formed and some plugins legitimately wish to save
whitespace as a config option (eg for search / replace characters).
Previously the assertion required the idx to be smaller than the number
of elements in the darray. This would mean you could not insert anything
at the end of a darray, and would make it impossible to insert an array
into an empty darray.
SIMDE was introduced for aarch64 support, however, the library itself
supports non-SIMD fallback, which allows us provide support to other
platforms without code changes.
There is another world beyond x86. So we can simply enable SIMDE for
processors without SSE2 support.

This uses three methods of obtaining the actual windows version,
RtlGetVersion which is the ntdll version of GetVersionEx that bypasses
the manifest check garbage, looking up the file version of a file that
is most likely to be updated per windows version (ntoskrnl), and the
registry. Of the three values, it chooses the highest windows version
obtained by the three.
