7f0984ea02 The syscall wrappers for sys_fcntl{,64} were too simplistic -- the 3rd 
arg is only used if the 2nd arg has particular values, so we were
getting false positives.  This commit makes the wrappers smarter to
account for this.  I updated the reg test too.

1524d5ac06 Converted the last syscalls. Phew. Still some cleaning up to do, esp. with 
socketcall() and ipc() which are done too simplistically.

Also, VG_([gs]et_thread_area)() both now return -VKI_EFAULT if they are given a
NULL pointer.

126c196c21 Converted the timer_* and clock_* syscalls. 
Also now checking the return value of every syscall in scalar, to make sure
that they (mostly) fail as expected.  Because occasionally one would succeed
unexpectedly and unaddressable memory would be marked as addressable, and
things would go haywire.  (The fact that the wrapper sets the memory as
addressable in these cases is a bug with the relevant wrappers;  I'll fix them
later.)

39914e513d Converted sigprocmask and rt_sigprocmask. 
While doing so, fixed bug #93328, by using the right sized types in
sigprocmask(), and converting them as necessary.  Added a regression test for
it too.

(partly) MERGE TO STABLE

ba41261f08 Converted modify_ldt() and init_module(); the old code for init_module() was 
seemingly totally wrong, as the man page doesn't reflect the real kernel code.

de135bbb7f After a clone system call there are two threads of control running so we 
need to make sure the child exits or we will get two copies of the output
from each test which follows. Also some older systems do not define the
CLONE_PARENT_SETTID flag.

c235901341 Now handling non-existent syscalls appropriately -- just returning ENOSYS 
rather than giving the warning about the syscall being missing.  (Nb: this only
applies to syscall numbers for which the kernel has no corresponding syscall;
Valgrind will still give that warning if new syscalls are added to the kernel.)
