Style(9) fix. Do not initialize variables in the declarations.

Sort include files in the alphabetical order.

Remove comment about 'ftlk' LOR.

Stop printing the LOR, as this is expected behavior.

The bitset field of freshly created futex should be initialized explicity.
Otherwise, REQUEUE operations fails.

Rename used_requeue and use it as bitwise field to store more flags.
Reimplement used_requeue logic with LINUX_XDEPR_REQUEUEOP flag.

Yet another unimplemented futex operation, print out about.

Sync: merge r215464 through r215708 from ^/head.

Remove trailing dot from the unimplemented futex messages to make
them consistent with the syscall and ipc messages.

Sync: merge r215319 through r215395 from ^/head, so ports can actually

- print out the PID and program name of the program trying to use an
unsupported futex operation
- for those futex operations which are known to be not supported,
print out which futex operation

- print out the PID and program name of the program trying to use an
unsupported futex operation
- for those futex operations which are known to be not supported,
print out which futex operation it is
- shortcut the error return of the unsupported FUTEX_CLOCK_REALTIME in
some cases:
FUTEX_CLOCK_REALTIME can be used to tell linux to use
CLOCK_REALTIME instead of CLOCK_MONOTONIC. FUTEX_CLOCK_REALTIME
however must only be set, if either FUTEX_WAIT_BITSET or
FUTEX_WAIT_REQUEUE_PI are set too. If that's not the case
we can die with ENOSYS right at the beginning.

Simplify timeout check in futex_wait() using itimerfix() and return error
if the given timeout is invalid. Consistently use int type for timeout and
correct a format string in futex_sleep().

Fix a comparision of an uninitialised pointer.
