Implemented EGL_KHR_create_context as described here:
www.khronos.org/registry/egl/extensions/KHR/EGL_KHR_create_context.txt
A small part of it was already implemented, which was to add

bitfield. Note that the EGL_OPENGL_ES3_BIT is explicitly disabled

Switch implementation
Implemented switch/case for glsl in OpenGL ES 3.0.
For simplicity, it is implemented as a loop without a condition,
so break statements work properly like so:
begin switch
if(...) // 1st case
...
else if(...) // other cases
...
else // default case
...
end switch // Anchor point for break statements
All related dEQP tests pass, except 7 tests where vertex shaders
contain a switch or a loop within another switch. These 7 failures
have only about 5% of bad pixel and seem to be related to an issue
with int(floor(...)), since the equivalent tests inside the fragment
shader pass.
KNOWN ISSUE: If a switch is within a loop and one of the cases
contains a "continue" statement, this will not be
handled correctly at the moment. There are no dEQP
tests for this at the moment, AFAIK.

Making proper use of size_t
In a lot of cases, int was being used instead of size_to represent
sizes. That led to some warnings about inconsistencies between int
and size_t usage. While this cl doesn't solve all warnings, it tries
to use size_t and int where it should be appropriate to use them.

Fix checking all mipmap levels for padding.
When textures have padding after a row of pixels, we can't use the sampler's
fast path which uses shift operations. We have to treat it as an NPOT texture.
Previously only mipmap level 0 was checked for padding, but when a texture is
also a render target we allocate 2x2 pixel blocks so a 1x1 mipmap has stride 2.

Compute cube LOD from 3D cube intersection distance.
We used to compute the cube map LOD by projecting all sampling rays onto the
same face (arbitrarily chosen). This changes it to intersect the rays with the
cube and use the 3D distance between them.

Fixed a couple of regressions from namespace refactoring
From the ES3 spec, section 4.4.2 (about DeleteRenderbuffers):
"Unused names in renderbuffers are silently ignored, as is
the value zero."
And from section 6.1.5:
"IsSampler will return TRUE if sampler is the name of a
sampler object previously returned from a call to
GenSamplers and FALSE otherwise".
Also, glIsSampler can use Context::isSampler(), which uses
ResourceManager::isSampler(), which should only look whether a
name has been reserved, not whether the object is allocated.
Note: Even though the spec mentions (about Sampler objects):
"they acquire state only when they are first used as a parameter
to BindSampler, SamplerParameter*, GetSamplerParameter*, or
IsSampler", it shouldn't hurt to not allocate the object when
calling IsSampler, since a subsequent call to any other Sampler
object related function should allocate it.
