talloc_tos() in common code

[Stefan (metze) Metzmacher]

Hi,

I wonder why we can't use the talloc_tos() infrastructure in common code?

I know that we can't use talloc_tos() directly, because the stackframe
might not be in place, but I think we could use something like this:

TALLOC_CTX *frame = talloc_stackframe();

some code ...

talloc_free(frame)

This way we'll make use of a talloc pool if the caller
used talloc_stackframe_pool().
