In release mode print the ralloc tree header pointers. In debug mode,
will look at the child allocations recursively checking for the canary
values. In most cases this should work and give us extra information
about the type of the subtree (GC, Linear) and the allocation sizes.
For example, calling it at the end of spirv_to_nir() will output the
following tree with a summary at the end (lines elided to focus on the
general structure of the output)

Now that linear_realloc() is unused, remove it. It is not an actual
realloc, will always allocate new memory and copy data around -- and
had a big warning about it in the documentation.
In the couple of uses we had before, the client code knew the size,
so it could be changed to perform the allocation and the copy by
themselves. The client code keeping the size is the recommended
way here.
This will allow us remove linear_size_chunk later.

In the linear allocation only the parent (context) can be used
to allocate new children, so let's use an opaque type to identify
the linear context. This is similar to what's done in GC allocator.
Update the documentation and a couple of function names to
refer to linear context instead of linear parent.

Linear allocator doesn't support calling custom destructors to
its child allocations nor freeing individual child allocations.
So the destructor callback and the delete operator don't apply
to objects using linear allocator.

None of the callsites took advantage of this, so remove
the feature. This will help to a next change that will
add an opaque type to represent a linear parent.

Unfortunately, we can't quite follow the standard C conventions for
these because ralloc doesn't know the sizes of pointers.

This function differs from ralloc_strcat() and ralloc_strncat()
in that it does not do any strlen() calls which can become
costly on large strings.

There was exactly one user of this, and I just removed it.
It also accessed an implicit global context, with no locking. This
meant that it was only safe if all callers of ralloc_autofree_context()
held the same lock...which is a pretty terrible thing for a utility
library to impose.

ralloc_adopt() reparents all children from one context to another.
Conceptually, ralloc_adopt(new_ctx, old_ctx) behaves like this
pseudocode:
foreach child of old_ctx:
ralloc_steal(new_ctx, child)
However, ralloc provides no way to iterate over a memory context's
children, and ralloc_adopt does this task more efficiently anyway.
One potential use of this is to implement a memory-sweeper pass: first,
steal all of a context's memory to a temporary context. Then, walk over
anything that should be kept, and ralloc_steal it back to the original
context. Finally, free the temporary context. This works when the
context is something that can't be freed (i.e. an important structure).

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.
