libobs: Prevent D3D11 projectors from tearing
...
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.

libobs-opengl: OpenGL thread-safety on Mac
...
Attempt to fix threading issues that cause OBS to force-crash when
compiled with latest Xcode. There are two places where the new SDK
introduces a force-crash because operations are not happening on the
main thread: when we modify the context view to switch swap chains, and
when we resize a swap chain.
Instead of using just one context for all rendering, we create an
additional context for each swap chain, set each view once on
initialization, and switch contexts only in present to blit the final
framebuffer. This is an extra copy, but it's pretty hairy to optimize
away, and it's not worth potential regressions just to speed up Mac.
For resizing, we schedule the update code to run on the main thread from
the render thread. Ideally, we wouldn't have to round trip the logic
from main thread to graphics thread and back, but I don't think we want
to hack up the interface for this, especially since OpenGL will give way
to Metal soon enough.

libobs-opengl: Require OpenGL 3.3 instead of 3.2
...
There don't appear to be any GPUs that support 3.2, but not 3.3. GLSL
330 maps to HLSL Shader Model 4, so this will theoretically make shaders
programs less likely to diverge, particularly for behavior around NaNs.

clang-format: Apply formatting
...
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.

libobs-opengl: Use windowless context (windows)
...
(Non-compiling commit: windowless-context branch)
On windows, you can just create a hidden window as the "main" opengl
window to get the equivalent of a windowless context. You might be able
to do it without a window, but honestly it's more trouble than it's
worth.

(API Change) Use const params where applicable
...
This Fixes a minor flaw with the API where data had to always be mutable
to be usable by the API.
Functions that do not modify the fundamental underlying data of a
structure should be marked as constant, both for safety and to signify
that the parameter is input only and will not be modified by the
function using it.

(API Change) Remove pointers from all typedefs
...
Typedef pointers are unsafe. If you do:
typedef struct bla *bla_t;
then you cannot use it as a constant, such as: const bla_t, because
that constant will be to the pointer itself rather than to the
underlying data. I admit this was a fundamental mistake that must
be corrected.
All typedefs that were pointer types will now have their pointers
removed from the type itself, and the pointers will be used when they
are actually used as variables/parameters/returns instead.
This does not break ABI though, which is pretty nice.

(API Change) Improve graphics API consistency
...
Summary:
- Prefix all graphics subsystem names with gs_ or GS_
- Unsquish funciton names (for example _setfloat to _set_float)
- Changed create functions to be more consistent with the rest of the
API elsewhere. For exmaple, instead of
gs_create_texture/gs_texture_destroy, it's now
gs_texture_create/gs_texture_destroy
- Renamed gs_stencil_op enum to gs_stencil_op_type
