On mips platforms the second cacheflush parameter is the number
of bytes in cache that needs to be flushed. When we are discarding
translation we need to use this number instead of:
((ULong) ARG2) - ((ULong) ARG1) + 1ULL
This patch also include syscall wrapper for __NR_sigaction on mips32.

Valgrind is doing mmap always with MAP_FIXED. On mips32 we need to check arg4.
If the arg4 is MAP_SHARED we need to align the address to SHMLBA.
If the program tries to do mmap with VKI_FIXED Valgrind doesn't need to align
the address to SHMLBA.

Another mmap issue in which another VG_(am_get_advisory) needs adjustment
wrapper for cases when (VKI_SHMLBA > VKI_PAGE_SIZE) and argument is
VKI_MAP_SHARED.

Necessary changes to Valgrind to support MIPS64LE on Linux.
Minor cleanup/style changes embedded in the patch as well.
The change corresponds to r2687 in VEX.

sys_socketcall was duplicated in syswrap-{ppc64|ppc32|arm|mips32|s390x}-linux.c
=>
* Similarly for what was done for sys_ipc, factorise the code in syswrap-linux.c
* re-enabled PRE_MEM_READ for VKI_SYS_SENDMSG and VKI_SYS_RECVMSG
(PRE_MEM_READ calls were commented out around 2003, for what
was supposed a glibc bug.
The PRE_MEM_READ calls were already re-enabled in s390x)
* s390x also had some more checking to verify the addressibility of
the args and fail the syscall with EFAULT if not addressable
=> same checks are now done for all platforms.
(tested on x86/amd64/mips32/s390x/ppc32/ppc64,
compiled for arm-android-emulator)

Enable wrappers for MIPS for the following two system calls:
- sys_settimeofday, and
- sys_stime.

The header file has been extended with the missing syscall numbers for MIPS,
and sys_prlimit64 has been enabled. This will make none/tests/rlimit64_nofile
pass.

This patch fixes incorrect handling of sys_shmdt for MIPS. Linux wrappers have
been added for sys_sigprocmask, sys_timerfd_create, sys_timerfd_gettime, and
sys_timerfd_settime on MIPS.
The bug has been reported at https://bugs.kde.org/show_bug.cgi?id=270777 as
sh_mat issue, and it can be reproduced with shmat-sample.c from
https://bugs.kde.org/show_bug.cgi?id=222545.
The change also fixes sigprocmask from memcheck tests.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@12658
Syscall pipe returns two descriptors in two registers, and thus a generic
Linux wrapper is not sufficient. This fixes none/tests/fdleak_pipe.
MIPS port is currently tracked as bug #270777.
