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.

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.
