2021-03-22vcl: fix libc epoll pwait starvedwanghanlin1-0/+3
We call vls_epoll_wait with 0 timeout to process unhandled_evts_vector in ldp_epoll_pwait_eventfd. But vls_epoll_wait will then call vppcom_epoll_wait_eventfd to process events in event queue. If there are continuous events to be handled, then libc_epoll_pwait have no chance to be called.

To enable add "app-socket-api /path/to/socket" to vcl.conf. On vpp side, add use-app-socket-api to session stanza in startup.conf VPP allocates a socket per application namespace which it places in the app_ns_sockets subfolder of the run folder (default /var/run/vpp).

2020-08-12vcl: support multi-threads with session migrationhanlin1-5/+8
Currently, mutlti-threads only support one dispatch thread and multiple worker threads, eventually only dispatch thread is a vcl worker and can interact with epoll. This patch will register all threads as vcl worker, and then each thread can interact with epoll now. Moreover, session migration also supported, such as socket created in thread A and used (bind, connect and etc.) in thread B.
