When the shader cache is used, this can be generated. In fact, the
shader cache uses this sha1 to lookup the serialized GL shader
program.
If a GL shader program is restored with ProgramBinary, the shaders are
not available, and therefore the correct sha1 cannot be generated. If
this is restored, then we can use the shader cache to restore the
binary programs to the program that was loaded with ProgramBinary.

Let's use the new gl_state_index16 type everywhere and remove
the typecasts.
This helps reduce the size of gl_program_parameter.

The ARB_get_program_binary extension requires that uniform values in a
program be restored to their initial value just after linking.
This patch saves off the initial values just after linking. When the
program is restored by glProgramBinary, we can use this to copy the
initial value of uniforms into UniformDataSlots.
V2 (Timothy Arceri):
- Store UniformDataDefaults only when serializing GLSL as this
is what we want for both disk cache and ARB_get_program_binary.
This saves us having to come back later and reset the Uniforms
on program binary restores.
