A few recently introduced graphics API functions needed for Enhanced
Broadcasting were marked as `GRAPHICS_IMPORT_OPTIONAL`. Add the
proper checks in the wrapper to ensure they are safe on platforms
that do not implement the underlying function.
Sprites were unnecessarily updating a dynamic vertex buffer every single
draw call. This creates static vertex buffers for common vertex buffer
dimensions/uvs and only uses a dynamic vertex buffer when the texture
coordinates actually change.
Porbably not a significant perf change considering the very few number
of traingles we draw per frame but still nice to do.
Optimizes certain 4x4 matrix functions by minimizing unnecessary math
operations. This ends up optimizing gs_matrix_transform() and
gs_matrix_rotate() functions and makes positional/rotational operations
a bit more optimal and requiring much less math than they would
otherwise.
Add graphics APIs to obtain the GPU driver version and renderer
strings, as well as GDDR memory sizes. The GDDR memory sizes
include the dmem (dedicated memory on the GPU) and smem
(shared CPU memory used by the GPU but resides in the CPU DDR).
The version and renderer strings are needed for identification
purposes, for example enhanced broadcasting used by Twitch, to
associate the GPU used by OBS with the PCIe-based identification
values such as device_id and vendor_id.
This change adds a new type named gs_sync_t and related functions to X11
and Wayland EGL backends to abstract DRM syncobjs and their various
uses.

NV12 and P010 device functions were not exported on all platforms.
Windows was exporting from C files instead. After CMake 3.0 we started
hiding symbols and resolution failed.
This adds gs_enum_adapters and gs_get_adapter_count to the opengl
backend and promotes these to multiplatform graphics functions.
However we need to make an internal device change, device_enum_adapters
must pass in the current device on opengl to ensure that adapter #0 is
the display adapter. We do this to avoid changes to plugins already
checking against obs_video_info.adapter which is always 0 and expected
to be the device OBS was initialized on.
The actual implementation reports the dri render node (or /Software).
This allows plugins to query non-video features of the adapters like
VA-API/NVENC/etc or other cross device functionality. `/Software` is
chosen to avoid opening random files in the current directory if its
passed along as a file path like the regular dri render nodes.

As clang and gcc use "default" visibility (as in "not hidden") when
no visibility is specified, all functions are implicitly exported.
When changing default visibility to "hidden", the corresponding symbols
are not exposed anymore and linking fails. This PR updates all
functions signatures that were added in recent commits but not set to
be EXPORTed.
Also makes required OpenGL imports for texture sharing on macOS
mandatory.
Some users stream projectors, so don't let them tear. Use the waitable
object to check the flip queue, and only flip if there's space.
Metal and Vulkan can probably perform similar flip throttling once OBS
starts using them.
