[PATCH v2 0/3] [florian/y2038] recvmmsg for timespec64

[Song Chen]

This patch serial is to introdule a new sycall recvmmsg64 to support
64-bit time_t.

All the test cases have been tested and passed and resource is cleaned
up before leaving.

At beginning, i tried to initialize socket like this way:
	socket(AF_UNIX, SOCK_STREAM, 0);

However, it returns immediately in __rtdm_fd_recvmmsg, couldn't
get valid value from rtdm_fd_get.

I'm not familiar with this part, i guess it's supported in GPOS
instead of xenomai, then i turned to IPCPROTO_XDDP, it works. Any
suggestion about this part is welcomed.

v2:
1, adjust indentation, different files have different indentation, see
   ./kernel/cobalt/posix/io.h
   ./kernel/cobalt/posix/syscall32.h
   I followed the function definition around mine
2, remove duplicated helper get_timespec64_xeno
   get_timespec64 is defined in vanilla kernel, that's why suffix _xeno,
   but it still looks weired, it does nothing but just call
   cobalt_get_timespec64, so why not call cobalt_get_timespec64 directly
   with a little change of its definition.
4, rename variables
5, remove unnecessary branches
5, call smokey_check_errno
