Add a form of synchronization between what worker will be accepting
...
new connections and which ones will not be notified for it.
Fixes the thundering herd problem, and nicely spreads out load between
all the workers equally. A configuration option (workers_max_connections)
is available to tweak how many connections a worker will have before
giving up the accept lock.
Two ways are added to this commit for access locking:
- Locking via semaphores.
- Locking via GCC's builtin atomic methods.
The default is running with semaphores disabled (OpenBSD cannot do
sem_init() with pshared set to 1, which is required).
If you want to use semaphores add KORE_USE_SEMAPHORES to CFLAGS,
and -lpthread to LDFLAGS in the Makefile.
Other fixes:
- BSD: add a timeout to kevent().
- Merge kore_worker_wait together, linux knows waitpid() as well.
- Send the correct SIGQUIT signal to workers instead of SIGINT.
- Fix kore_time_ms().
- Log fatal worker messages in syslog.
- Refactor code even more.
- Do not free our own kore_worker structure.

rework the way events trigger and the way we handle them. follow the manual for once, as edge trigger does not refire until we got an EAGAIN.
...
introduce net_send_flush() and net_recv_flush() for this purpose, we attempt to make as much headway as possible until we reach EAGAIN or until we can simply pickup again later.
should merge all the stuff in http_response() into a single send buffer, **out is in place in net_send_queue() for that purpose.
