If the string being copied is not NULL-terminated the result of
strlen() is undefined.

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.
