Add methods to return the properties of the base level image of a texture. We can call these of any texture type.

These methods are only well-defined for complete textures (IE, not cube maps with one face defined in one level).

1. For overflowing the currently bound pixel unpack buffer in TexImage and TexSubImage calls.
2. Enforce unpack buffer offset alignment for TexImage and TexSubImage calls.
We'll have to check for currently mapped buffers when we implement map.

This is to work around driver bugs where shader compile or program link would fail incorrectly if gl_Position is not set in vertex shader.

At the moment at least Linux NVIDIA driver has this bug.

Used pointers for precision-stack entries as well to avoid unnecessarily re-allocating PrecisionStackLevel whenever the vector needs to resize.

Bison calls yyerror("syntax error") when it cannot match any grammar rule.
We used to append current token string to the error message,
which got broken in r2202.

We used to allocate thread-local memory on each compile.
If the compile did not happen on the same thread as ShInitialize,
we leaked the thread-local memory.

It turns out that there is no need to allocate any thread-local
memory. This patch cleans up all the unnecessary junk around TLS.
