Make sure we do not reference our internal talloc directly. Let configure define what talloc.h file to use so that builds that use an extrenal talloc do not include 2 different versions of the talloc header.

* Implement a stack of talloc frames.

*
|
|
* When a new talloc stackframe is allocated with talloc_stackframe(), then
|
|
* the TALLOC_CTX returned with talloc_tos() is reset to that new
|
|
* frame. Whenever that stack frame is TALLOC_FREE()'ed, then the reverse
|
|
* happens: The previous talloc_tos() is restored.
|
|
*
|
|
* This API is designed to be robust in the sense that if someone forgets to
|
|
* TALLOC_FREE() a stackframe, then the next outer one correctly cleans up and
|
|
* resets the talloc_tos().
