Previously, vrend_shader insterted a scale & bias to emulate
glDepthRange in all vertex shaders. This approach will fail
to match the gl spec in some situations. glDepthRange() is also
called, causing the transformation to be applied twice. The
winsys_adjust uniform is now a scalar to implement the y-flip only.
This bug was discovered and tested using the
dEQP-GLES2.functional.depth_range test suite. This test now passes
all but one case, which appears to be a separate issue.

If we bind a GL program with a given id, then destroy the program and
its id, then immediately create another program which ends up with
the same id, we won't be able to tell that a new program needs to be
bound, and we will access freed data. This results in funny crashes.
We fix this by setting the program to 0 when a different shader is
being bound. This will force the draw code to bind the proper program
later on.
This fixes a lot of semi-random crashes. To debug it I used this
particular deqp test which becomes stable with this change:

Currently, we always try to create an OpenGL 3.1 context. Some
dEQP tests require an OpenGL 3.2 context (specifically, ones
that use glGetInteger64v). Let's try to create the highest
version context we can, and iterate to lower versions, i.e:
https://developer.android.com/guide/topics/graphics/opengl.html#version-check
The return code for (*create_gl_context) is a little unclear.
This patch assumes NULL is returned on failure. This should work
for GLX and EGL.
GLX:
"On failure glXCreateContextAttribsARB returns NULL and generates
an X error with extended error information"
https://www.khronos.org/registry/OpenGL/extensions/ARB/GLX_ARB_create_context.txt
EGL:
"#define EGL_NO_CONTEXT ((EGLContext)0)"
https://www.khronos.org/registry/EGL/api/1.1/EGL/egl.h
The semantics of rcbs->create_gl_context may be different, though.
