Add a global singly-linked list of all active talloc pools, so that we
can eventually show how much memory is used for different purposes.
This also gives a check that pools are not being doubly freed.
talloc_init_named now handle a NULL name properly (ie does nothing)
Add accessor talloc_pool_name().
(This used to be commit 4c6c03c8c7)
ancient mem_man.c:
Each TALLOC_CTX now has a field to store its purpose, to aid in
tracking down memory bloat. A new call talloc_init_named() should be
used instead of talloc_init() so that this is set.
Added talloc_vasprintf to be called by varargs functions.
(This used to be commit 25b97a7435)
advantages:
- memory is trackable by insure
- a very simple talloc_realloc() is possible (I've added it)
It is slower than the previous talloc code, but I don't think that
is going to be a problem. If it is a problem then there are
some ways we can make it faster but I'd like to leave those
until we have tested this a bit and can see what performance
problems might show up in profiling

pool is getting bloated. Also added a talloc_zero function to return zeroed memory.
Added debug in rpc_server/srv_pipe_hnd.c so we know when a talloc pool is being
freed. Syncup with srv_pipe_hnd.c from 2.2 so we are freeing memory at the same time.

memory access.
Tridge, I don't think using 0xdeadbeef for size allocations
of 0 is going to work. I ended up having to use NULL
as much code that works on UNISTR checks to see if the buffer ptr
is NULL. So valid code ends up with a seg fault.
Rather than rewriting it all, I added a DEBUG_TALLOC
#ifdef in talloc.h that sets a macro BAD_PTR.
This is the value assigned to ptr for an allocation of 0 bytes.

(This used to be commit 233b9cffa2)
in the RPC code. This change was prompted by trying to save a long (>256)
character comment in the printer properties page.
The new system associates a TALLOC_CTX with the pipe struct, and frees
the pool on return of a complete PDU.
A global TALLOC_CTX is used for the odd buffer allocated in the BUFFERxx
code, and is freed in the main loop.
This code works with insure, and seems to be free of memory leaks and
crashes (so far) but there are probably the occasional problem with
code that uses UNISTRxx structs on the stack and expects them to contain
storage without doing a init_unistrXX().
This means that rpcclient will probably be horribly broken.
A TALLOC_CTX also needed associating with the struct cli_state also,
to make the prs_xx code there work.
The main interface change is the addition of a TALLOC_CTX to the
prs_init calls - used for dynamic allocation in the prs_XXX calls.
Now this is in place it should make dynamic allocation of all RPC
memory on unmarshall *much* easier to fix.

(This used to be commit 0ff2ce543e)
lp_string() bug properly.
we still need to add lp_talloc_free() calls in all the main event
loops, I've only put it in smbd and nmbd thus far.
