TLS can enqueue events to itself when app session queue cannot be
entirely drained. If a pending disconnect is handled before any such
event, session layer may try to dequeue data on deallocated sessions.

If sessions are marked as blocking, events for other sessions received
while waiting for the blocking sessions, are added to a pending list and
processed later.

- support eventfd based mq signaling. Based on configuration, vcl
epoll/select can use either condvars or epoll on mq eventfds.
- add vcl support for memfd segments
- vpp explicitly registers cut-through segments with apps/vcl
- if using eventfd, make ldp allow one call to libc_epoll_create. Needed
for the message queue epfd
- update svm_queue_t to allow blocking calls with eventfd signaling.

Have vcl poll and wait on the event message queues as opposed to
constantly polling the session fifos. This also adds event signaling to
cut through sessions.
On the downside, because we can't wait on multiple condvars, i.e., when
we have multiple message queues because of cut-through registrations, we
do timed waits.

- cache and reuse tcp options and rcv_wnd for session layer tx bursts
- avoid reading/setting total_length_not_including_first_buffer. It's
part of a buffer's second cache line so it comes at a "cost".

It would seem that this avoids using the stack for computing the
subsequent crc32 by storing the 2 x u64 ip4 5-tuple key into two
registers. Probably the cast to the "convenience" data structure "masks"
the fact that the key is 16B. Probably ... :-)
"sh run" on an ip4 tcp sender reports that the number of clocks spent in
tcp_input, where a session lookup is performed, drops ~25% (from ~100
clocks/packet to ~75 clocks/packet)

- Cleanup session state after last ack and avoid using a cleanup timer.
- Change session cleanup to free the session as opposed to waiting for
delete notify.
- When in close-wait, postpone sending the fin on close until all
outstanding data has been sent.
- Don't flush rx fifo unless in closed state

is started with multiple wokers, allocate connections on the first. Also
add a simple udp make test.

If the caller is the session owning thread or the main thread with a
worker barrier sync (cli/api) add an event to the pending disconnects
vector in the session node and entirely avoid using the event queue.
Useful for bursts of disconnects (like an app detach).
If disconnects come from a processes, be willing to retry enqueueing the
disconnect to the event queue multiple times.
