b4db34cc4c glsl: Rename uniform_field_visitor to program_resource_visitor.
There's actually nothing uniform-specific in uniform_field_visitor.
It is potentially useful for all kinds of program resources (in
particular, future patches will use it for transform feedback
varyings).

This patch renames it to program_resource_visitor, and clarifies
several comments, to reflect the fact that it is useful for more than
just uniforms.

NOTE: This is a candidate for the 9.1 branch.

99b8935ce2 glsl: Add new uniform_field_visitor::process variant
This flavor takes a type and a base name.  It will be used to handle
cases where the block name (instead of the instance name) is used for an
interface block.

b226a058db linker: Refactor intra-stage block compatabililty testing
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.

4b11b57ab4 glsl: Separate varying linking code to its own file.
linker.cpp is getting pretty big, and we're about to add even more
varying packing code, so split out the linker code that concerns
varyings to its own file.

8292b7419d ralloc: Make rewrite_tail increase "start" by the new text's length.
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).

586e741ac1 linker: Make linker_error set LinkStatus to false
Remove the other places that set LinkStatus to false since they all
immediately follow a call to linker_error.  The function linker_error
was previously known as linker_error_printf.  The name was changed
because it may seem surprising that a printf function will set an
error flag.
