Introduce faulthandler to print stack trace to stderr on python crash.
Don't disable automatic garbage collection to decrease the chances of
running out of memory.

The main interior graph-node dispatch loop had a longstanding dangling
vector element reference:
for (i = 0; i < _vec_len (nm->pending_frames); i++)
cpu_time_now = dispatch_pending_node (vm, nm->pending_frames + i,
cpu_time_now);
Passing a pointer to a vector element (nm->pending_frames + i) has
considerable comedic potential if there's any chance that the vector
could expand.
dispatch_pending_node() calls dispatch_node(), and indirectly any
interior graph node dispatch function. If that node happens to expand
nm->pending_frames by filling in a new frame, nm->pending_frames can
expand.
After calling the node dispatch function, dispatch_node() does the
following:
nf = vec_elt_at_index (nm->next_frames, p->next_frame_index);
If nm->pending_frames expands during dispatch function execution, p is
a dangling reference to freed memory.
By luck, the TCP stack managed to allocate a fresh frame which
included "old-p," which caused p->next_frame_index to be filled with
the new-frame poison pattern 0xfefefefe.
This has been broken from day 1, summer 2007, first use of the
third-generation vector processing library.

Attempting to supply within a VAT CLI to add the ACLs a rule count
override with no rules to add would result in null pointer dereference
as we attempt to copy those rules to the message.
Add the check to avoid copy if the source pointer is null
(i.e. if there are no rules to copy from).
This commit fixes coverity errors 166797 and 166792.

VPP crash is observed when MAC aging is enabled with multi-threaded mode.
If a thread other-than-zero expands the working_copies vector,
working_copy_lengths should be initialized with vec_validate_init_empty(..., -1)
to fill -1 across lower-numbered working_copy_lengths vector element.

Add runtime debug vhost-user on | off CLI to facilitate troubleshooting.
This feature is needed to avoid recompiling the code to debug vhost issues.
The debugging messages should not be on the data path to avoid performance

- Add rx-queues and tx-queues option to the create memif CLI
- Add vlib_worker_thread_barrier_sync () to memif_conn_fd_read_ready () as
the latter function may disconnect the ring and clean up the shared memory.
- On transmit, write the rid (queue number) to the socket.
- On receive, read the rid and trigger the interrupt for the corresponding
thread.
