SOCK_CTRL is added to provide special control over network drivers
and daemons. Currently, SOCK_DGRAM and SOCK_STREAM perform this control,
but these use socket resources. In the case of usersocket in particular,
this is a waste of the device's limited socket resources.

NuttX kernel should not use the syscall functions, especially after
enabling CONFIG_SCHED_INSTRUMENTATION_SYSCALL, all system functions
will be traced to backend, which will impact system performance.

epoll_wait collects revent by checking fds->revent,
but local_socket will copy fds to the other two private pollfd shandow struct,
then the pipe_poll will not be able to update fds->revent directly,
so need local_socket save fds and implement a private poll_notify function
to passing revent to original fds->revent.

server:
at accept last nxsem_post(&client->lc_waitsem);
client:
connect wait(&client->lc_waitsem) then local_open_client_rx();
But if the server priority is higher then client,
and after server accept return, immediately call send().
At this time the client has no way do local_open_client_rx().
Then server send() return error.
Fix:
add lc_done sem to client
