ARM: fixed *jmp() functions

With soft-fp, the previous __sigsetjmp() implementation modifies a
buffer pointing 48 bytes before the correct one.  Was broken at
2001-03-16 by the "add several functions to make busybox compile and
partially link" commit...

Nevertheless, there are further patches required which save the
co-processor registers (e.g. the iwmmxt ones) of recent cpus.  The 'lfm'
in the __SOFTFP__ clause is very ancient and will not work with recent
hard-fp capable cpus.

Patch adds testsuite programs for sigjmp() + sigsetjmp() functionality.

ARM: added neon-fp support in sigjmp code and enhanced testsuite to verify that fp registers are restored correctly
fadvise: optimized C wrapper and fixed posix_fadvise() implementation

Include fadvise64_64() headers only when required and #define
_LINUX_SOURCE.

Use assembly '.set' to declare posix_fadvise(); this copies symbol size
information and does not rely on alignment of the fadvise64() syscall.

time: use common implementation calling gettimeofday()

Instead of providing yet another arm/__time.c file for ARM-EABI, this
patch merges existing time(2) implementations (which did all the same
thing but with different code) into one global source file.  Build of
it depends on the existence of the __NR_time symbol.

The x64_64 implementation of time.S was moved to __time.S and an empty
time.S file was added to build from the correct VPATH.
ARM: use a common implemention for syscall_weak for EABI and OEBI by calling syscall() macro
ARM: unified declaration of assembler function

Previously, specification of alignment and symbol function differed
without any reason and the symbol size was sometimes missing too.

Patch uses FUNC_START and FUNC_END macros to declare assembler
functions in a common way.
ARM: replace 'mov pc, lr' and 'bx lr' with RET from <arm-features.h>

ARM: use thumb compatible __testandset() implementation

NOTE: this is not really complete.  Although the pthread implementation
calls this function to set a spinlock, this lock is cleared by writing
a value directly into it.  This will break the strex functionality.

pthread should be rewritten to use the gcc intrinsics
__sync_lock_test_and_set() and __sync_lock_release().
ARM: added some .size annotation
ARM-EABI: added __unified_syscall_swi which saves one instruction per syscall
ARM-EABI: removed __unified_syscall4; it is not for ARM EABI and its semantic conflicts with __unified_syscall_swi
ARM-EABI: fixed and optimized mmap(2) syscall

Previous implementation called __NR_mmap2 without converting the
offset argument into pages and did not handled the error.

Use the common mmap(2) implemention instead of.
