This extension allows the user to specify whether a full flush is performed when making a context not current.
The only way to set this currently is at context creation, so this patch provides that functionality.
Defualt behaviour is set at FLUSH, as per the spec.
This patch does not contain the changes to WGL, appleGL or other platforms as I do not have access to GL 4.5 hardware on those platforms.
Full details on the use of KHR_context_flush_control can be found here:

Various constants in ANGLE/WinRT, both in MSOpenTech's ms-master branch, and
in Google's branch, were changed again. This change makes SDL/WinRT work with
them.
To note, the ms-master branch (of ANGLE) was updated via this merge:
bbd2eb0a9c (diff-d1377fbe747de154e1bfcf7221d3de67)
If the function WIN_ConvertUTF32toUTF8() failed (should currently not be
possible) a not terminated string would have been sent as text input event.
This also fixed converting characters more often than needed on key repetition.
If the function Emscripten_ConvertUTF32toUTF8() failed (should currently not be
possible) a not terminated string would have been sent as text input event.
The key event callbacks were always removed from the same target although it is
possible to set them to different targets using the hint. This is only a partial
fix because it assumes that the hint is not changed to a different value later.
This allows for this kind of code in an application:
int monitorID = 1; // the second monitor!
SDL_SetWindowPosition(sdlWin,
SDL_WINDOWPOS_CENTERED_DISPLAY(monitorID),
SDL_WINDOWPOS_CENTERED_DISPLAY(monitorID));
Fixes Bugzilla #2849.
It's slightly faster than failing later, after a strchr() call, since this
will get called multiple times with a NULL string if the system totally
fails elsewhere.
This change integrates initialization settings for ANGLE/WinRT, as suggested in
MSOpenTech's latest ANGLE template-projects (for MSVC).
This should fix some OpenGL initialization issues on WinPhone 8.1 on ARM, and
on the 1st-generation Surface RT.
- Don't create a temporary context first; this was probably due to Windows
needing one to get the address of wglCreateContextAttribsARB(), but that's
a unique quirk of WGL, and doesn't apply to glX. The glX spec explicitly says
you have to get a function pointer that works with any context from
glXGetProcAddress(), including when no context exists.
- Properly check for the GLX_ARB_create_context instead of just looking for a
non-NULL glXCreateContextAttribsARB()...some implementations, like Mesa,
never return NULL for function lookups (Mesa returns pointers into a jump
table that is filled out when the GL is initialized; since you can look up
functions before you have a valid context, it can't definitely say a function
isn't valid at that point).
Normally there's a 200 millisecond delay on all focus events in case there
was a vidmode change, now we note the last vidmode change and only impose this
delay if a change happened extremely recently.
Thanks to Epic Games for reporting this issue.

The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c.
I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.
