futex: print uaddr value

Browse Source 
As it might be of interest. Since uaddr itself is as important as the
containing value, it's alwais printed as comment.

* xlat/futexpiflags.in: New file.
* futex.c [!FUTEX_TID_MASK] (FUTEX_TID_MASK): New macro constant.
Include "xlat/futexpiflags.h".
(printaddrnum, printaddrpival): New functions.
(SYS_FUNC(futex)): Use printaddrpival/printaddrnum for printing uaddr
and uaddr2 values where appropriate.
* tests/futex.c: Update expected output.
