linux-user: correct syscall 123 on sh4

As reported by Cédric VINCENT:

The syscall #123 on SH4 should be "TARGET_NR_cacheflush" instead of
"TARGET_NR_modify_ldt" [1]. The only consequence of this misnaming is
that many "Unsupported syscall" warnings are issued when emulating JIT...

mips: rlimit codes are not the same

The codes for get/setrlimit differ between linux target platforms.
This patch adds conversion.
This is important else programs (rsyslog, python, ...) can go into a
near infinite loop trying to close all the file descriptors from 0 to...

mips: rlimit incorrectly converts values

Byte swap was applied in the wrong order with testing for
RLIM_INFINITY. On mips bigendian from an amd64 system this results in
infinity being misinterpretted as 2^31-1.

This is a serious bug because it causes setrlimit stack size to kill...

mips: null pointer deref should segfault

Dereferencing a null pointer causes an exception 0xC (EXCP_AdEL)
instead of EXCP_TLBL. This should also trigger a segfault.

mips: missing syscall returns wrong errno

Return -TARGET_ENOSYS instead of -ENOSYS from linux-user/main.c * Caused strange 'Level 2 synchronization messages' instead of
correctly reporting the syscall was missing. * Made glibc simply fail instead of using older syscalls...

mips: sigaltstack args

The syscall sigaltstack takes two parameters, not zero. This patch
should have no impact as only values above 4 influence the runtime
behaviour. Nevertheless, it is wrong.

linux-user/syscall.c: Enforce pselect6 sigset size restrictions

Enforce the same restriction on the size of the sigset passed to
pselect6 as the Linux kernel does. This is both correct and silences
a gcc 4.6 warning about a write-only variable.

linux-user: Add syscall numbers from kernel 2.6.39.2

WebKit/DirectFB.
