  b2b_entities: properly handle BYE while another request is pending

Instead of rejecting the BYE with 491, first complete the transactions on the
UAS side with 200 OK for the BYE and 487 for the other pending transaction.
Also, mark the tuple for deletion at b2b_logic level and send a BYE to
the peer entity after completing any UAC transcations on this side.

  Log Message:
  -----------
  Add support for in-memory logging of shm operations

This is enabled via the new 'shm_memlog_size' global parameter which
configures the maximum number of operations to keep in the history.
A separate memory block, dedicated for this shm debug info will be
allocated. A single 'struct struct_hist' type object will be added to the
list for each alloc/free operation.
