libobs-opengl: Request at least 8 bits for alpha
...
10bpc support is under active development all over the linux stack
so while we wait for it to mature, request an alpha size of 8.

libobs-opengl: Log OpenGL version on all systems
...
This commit logs the OpenGL version on all operating systems and brings
the OpenGL subsystem's initialization logging more in line with the
D3D11 logging to make logs more uniform.

libobs-opengl: Add xcb message poll to empty out the queue
...
The xcb message queue is not currently emptied. If errors are generated
by any void requests the message queue will simply fill up and messages
will never be deleted.
Due to a (currently unknown) other problem this happens for me, and
results in OBS using up all memory with a queue that will never be
emptied.
Here we add a poll loop that will empty the xcb message queue and
discard the messages. While this means that errors are still not
handled, OBS wont end up crashing either.

libobs-opengl: Terminate visual attribs with None

libobs-opengl: Use windowless context (X11)
...
(Non-compiling commit: windowless-context branch)
In the land of X11, life is suffering.
Suffering aside, X11 is capable of a hardware-accelerated windowless
context by using a GLXPbuffer in conjunction with glXMakeContextCurrent.

(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

This commit contains more than I intended. Read below for more info.
...
1) Fixed the preview window. It now correctly displays the source.
2) The GLX backend now correctly uses the devices current swap.
3) We now set device->cur_swap to a default so we don't have to check it in every function.
4) Minor syntactical cleanups and perhaps some messiness added.

A few changes concerning wxGTK.
...
For one, I added a new member gs_window for future use.
The member is "display" which represents our connection to X11.
Ideally, we should use this specific connection to deal with our Window.
For now, it's disabled. Read comment for more information.
Secondly, wxGTK apparently doesn't map our window in some cases.
This causes the window ID passed to be bad and will stop (or segfault)
our program. This might be related to the first commit above.
For now, all this commit does is realize the window manually.
