-/* this is a very simple temporary memory allocator. To use it do the following:
-
- 1) when you first want to allocate a pool of meomry use
- talloc_init() and save the resulting context pointer somewhere
-
- 2) to allocate memory use talloc()
-
- 3) when _all_ of the memory allocated using this context is no longer needed
- use talloc_destroy()
-
- talloc does not zero the memory. It guarantees memory of a
- TALLOC_ALIGN alignment
