2018-10-02tls: fix disconnects for sessions with pending dataFlorin Coras3-4/+13
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.

2018-08-10vcl: support for eventfd mq signalingFlorin Coras9-69/+249
- 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.

2018-07-27vcl: use events for epoll/select/read/writeFlorin Coras9-32/+46
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.
