When emulating GL_ALPHA8 with GL_R8, we should make the alpha
component equal to the red color channel.
Fixes:
['dEQP-GLES2.functional.texture.mipmap.2d.generate.a8_fastest']
['dEQP-GLES2.functional.texture.mipmap.2d.generate.a8_nicest']
on OpenGL 4.5 (core).

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.
Fixes:
dEQP-GLES3.functional.state_query.integers.max_vertex_output_components_getinteger64
dEQP-GLES3.functional.state_query.integers.max_vertex_output_components_getfloat

OpenGL ES does not have glDrawBuffer, but it does have glDrawBuffers. It has
been available in Desktop OpenGL since 2.0 and was exposed in OpenGL ES 3.0.

The 'blit_ctx->initialised' is not setted to true.
Every time init blit context, it will create a new
'blit_ctx->gl_context' thus causing a memory leak.
This patch avoid this.
