Andrew Tridgell 577218b2ad r4640: first stage in the server side support for multiple context_ids on one pipe
this stage does the following:

 - simplifies the dcerpc_handle handling, and all the callers of it

 - split out the context_id depenent state into a linked list of established contexts

 - fixed some talloc handling in several rpc servers that i noticed while doing the above
(This used to be commit fde042b3fc609c94e2c7eedcdd72ecdf489cf63b)
