Share ArrayString and Str helper methods.
Placing these string helper methods allows us to re-use them in
the relevant place of the shader translator.

Use the sh namespace for shader variables.
Since these types originate from the translator, use an appropriate
namespace. Also rename some of the gl helper functions to be more
specific to their functionality.

Refactor and unify HLSL varying signatures.
We would use different code for all of our input and ouput stages
in HLSL (vertex output, GS input, GS output, PS input). This was
causing an HLSL error and some bugs in certain transform feedback
instances.
Fix this by using a helper method to use compatible code for each
of the stages.

Generate pixel shader output to match the bound framebuffer.
Only generate pixel shader output variables for render targets that are
currently bound. Fixes some performance issues with D3D10 cards that were
slow to discard unused outputs.
Fixed memory leaks in ProgramBinary by refactoring the freeing of the
current state into a reset function.

Split register allocation of varyings from the translator.
The translator gl::Varying struct does not need to know about register
allocation. We can put that entirely in the API library. This makes
exposing Varying variables with the new translator types cleaner.

Stop generating duplicate vertex binaries.
We would generate multiple vertex binaries that result in the same
HLSL code, eg for vec2 and vec3 vertex attributes. Eliminate
duplicates by using the converted attribute type for testing
for matching binaries.

Move ShaderVariables to common shared source.
Also move the block layout encoding utilities to the common folder.
The combined changes allow us to include the shader and block code
into both libGLESv2 and the translator separately. This in turn
fixes the Chromium component build, where we were calling internal
translator functions directly from libGLESv2.

The patch refactors the vertex input HLSL to allow for dynamic
conversion in the future. Using a placehold keyword, the code
