Also slightly change the compatibility test. Instead of comparing the
offsets of the block variables, compare the packing mode of the blocks.
Ideally we don't want to assign the offsets until a later stage of
linking.
This is put in a new file called link_uniform_blocks.cpp. Some new
functions related to uniform blocks are going to live in that file as
well.

Previously, we were returning the index into the UniformBlocks of one of the
linked shaders, when it's supposed to be the program global index.

When converting var->location from pointing at the program's UniformBlocks to
pointing at the linked shader's UniformBlocks, I missed this change. It
usually worked out in the end because the two lists happen to be the same in
many testcases.

At this point in the linking, we've totally lost track of the struct
gl_uniform_buffer that this pointed to in the original unlinked
shader, so we do a nasty n^2 walk to find it the new one based on the
variable name.
Note that these point into the shader's list of gl_uniform_buffers,
not the linked program's.

The spec requires that samplers be initialized to 0. Since this
differs from the 1-to-1 mapping of samplers to texture units assumed
by ARB assembly shaders (and the gl_program structure), be sure to
propagate this date from the gl_shader_program to the gl_program.

Both callers of rewrite_tail immediately compute the new total string
length by adding the (known) length of the existing string plus the
length of the newly appended text. Unfortunately, callers generally
won't know the length of the new text, as it's printf-formatted.
Since ralloc already computes this length, it makes sense to add it in
and save the caller the effort. This simplifies both existing callers,
but more importantly, will allow for cheap-appending in the next commit.
v2: The link_uniforms code needs both the old and new length.
Apply the obvious fix (which sadly makes it less of a cleanup).
