For a long time, we've wanted a place to put utility code which isn't
directly tied to Mesa or Gallium internals. This patch creates a new
src/util directory for exactly that purpose, and builds the contents as
libmesautil.la.
ralloc seemed like a good first candidate. These days, it's directly
used by mesa/main, i965, i915, and r300g, so keeping it in src/glsl
didn't make much sense.

That information misleads source code auditing tools to think that
ralloc itself is released under LGPL v3.
Instead, simply state talloc is not licensed under a permissive license.
v2: Use wording suggested by Kenneth.

This patch makes sure that class destructors are called as they should
be when a C++ object allocated by ralloc is released.
Based on a previous patch by Kenneth Graunke, but it doesn't exhibit
the ~0.8% performance regression in shader compilation times because
we now use the HAS_TRIVIAL_DESTRUCTOR() macro to detect the typical
case where the indirect function call can be avoided because the
object's destructor doesn't need to do anything.

Using it encourages the (IMHO worrying) practice of leaving member
variables uninitialized in constructor definitions. This macro
shouldn't be necessary anymore after the last patch series fixing all
its users to initialize all member variables from the class
constructor. Remove it.

Most of our C++ classes define placement new and delete operators so we
can do convenient allocation via:
thing *foo = new(mem_ctx) thing(...)
Currently, this is done via a lot of boilerplate. By adding simple
macros to ralloc, we can condense this to a single line, making it
trivial to add this feature to a new class.

glcpp-parse.y:1990:39: warning: format '%lli' expects argument of type

As a side-effect, remove ralloc.c's likely/unlikely macros and just use
the ones from main/compiler.h.
NOTE: This is a candidate for the release branches.

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).

This can be useful if you want to create a bunch of temporary strings
with a common prefix. For example, when iterating over uniform
structure fields, one might want to create temporary strings like
"pallete.primary", "palette.outline", and "pallette.shadow".
This could be done by overwriting the '.' with a null-byte and calling
ralloc_asprintf_append, but that incurs the cost of strlen("pallete")
every time...when this is already known.
These new functions allow you rewrite the tail of the string, given a
starting index. If the starting index is the length of the string, this
is equivalent to appending.
