Attilio Rao ce42e79310 Remove dead code from umtx support:
- Retire long time unused (basically always unused) sys__umtx_lock()
  and sys__umtx_unlock() syscalls
- struct umtx and their supporting definitions
- UMUTEX_ERROR_CHECK flag
- Retire UMTX_OP_LOCK/UMTX_OP_UNLOCK from _umtx_op() syscall

__FreeBSD_version is not bumped yet because it is expected that further
breakages to the umtx interface will follow up in the next days.
However there will be a final bump when necessary.

* System call arguments come in several flavours:
* Hex -- values that should be printed in hex (addresses)
* Octal -- Same as above, but octal
* Int -- normal integer values (file descriptors, for example)
* Name -- pointer to a NULL-terminated string.
* BinString -- pointer to an array of chars, printed via strvisx().
* Ptr -- pointer to some unspecified structure. Just print as hex for now.
* Stat -- a pointer to a stat buffer. Prints a couple fields.
* Ioctl -- an ioctl command. Woefully limited.
* Quad -- a double-word value. e.g., lseek(int, offset_t, int)
* Signal -- a signal number. Prints the signal name (SIGxxx)
* Sockaddr -- a pointer to a struct sockaddr. Prints symbolic AF, and IP:Port
* StringArray -- a pointer to an array of string pointers.
* Timespec -- a pointer to a struct timespec. Prints both elements.
* Timeval -- a pointer to a struct timeval. Prints both elements.
* Timeval2 -- a pointer to two struct timevals. Prints both elements of both.
* Itimerval -- a pointer to a struct itimerval. Prints all elements.
* Pollfd -- a pointer to an array of struct pollfd. Prints .fd and .events.
* Fd_set -- a pointer to an array of fd_set. Prints the fds that are set.
* Sigaction -- a pointer to a struct sigaction. Prints all elements.
* Sigset -- a pointer to a sigset_t. Prints the signals that are set.
* Sigprocmask -- the first argument to sigprocmask(). Prints the name.
* Kevent -- a pointer to an array of struct kevents. Prints all elements.
* Pathconf -- the 2nd argument of pathconf().
*
* In addition, the pointer types (String, Ptr) may have OUT masked in --
* this means that the data is set on *return* from the system call -- or
* IN (meaning that the data is passed *into* the system call).
