Ok - this is a *BIG* change - but it fixes the problems with static strings 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. Jeremy. (This used to be commit 0ff2ce543ee54f7364e6d839db6d06e7ef1edcf4)

implemented talloc() as described on samba-technical. This fixes the 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. (This used to be commit aa7f81552540f5dca2c146f5edd805611d5b390f)

Samba temporary memory allocation functions
Copyright (C) Andrew Tridgell 2000
Start adding some debugging features to talloc based on Samba's 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 25b97a743573b8c5e0ac886e4bfab581c11b3714)

/**
* talloc allocation pool. All allocated blocks can be freed in one go.
**/
Make TALLOC_CTX and talloc_chunk private to talloc.c. 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().

Add talloc_asprintf_append, which grows an existing string buffer to contain new print-formatted information. (Also talloc_vasprintf_append.) Idea borrowed from glib. (This used to be commit 53723e874885936dd67483ebf46601fc73489d17)
