pread/write wanted to send an 8 byte value in the syscall where only 4 bytes
were allowed.

Pass via r4 the rtld finalizer
_dl_fini to the user application. This will be the 6^ arg of
__uClibc_main and will be registered with 'atexit'.
In this way the dynamic linker will be able to call destructors
defined within the loaded DSOs.

- adds #warning about incorrect posix_fadvise{,64}()
- removes unused and unwanted uselib()
Net outcome is that an allnoconfig with HAVE_SHARED is now about 88k instead
of formerly 130k.

For -combine, make sure that we don't pollute our non-varargs mremap decl
with some vararg decl from later in the TU by putting ours after anybody
else who is picking up mman.h.
This is admittedly a small work-around..
smallish testcase:
$ cat bug.h
extern void *mremap (void*, unsigned, unsigned, int, ...);
$ cat bug1.c
#include "bug.h"
int whatever;
$ cat bug2.c
#define mremap _hidemremap
#include "bug.h"
#undef mremap
void *mremap (void*, unsigned, unsigned, int, void*);
$ gcc -c bug1.c bug2.c
$ gcc -c bug1.c bug2.c -combine
bug2.c:4: error: conflicting types for ‘mremap’
bug.h:1: error: previous declaration of ‘mremap’ was here

Add the necessary prototypes and definitions for splice(), vmsplice()

in string.h and strings.h. This caught unguarded string ops in
libc/inet/ethers.c __ether_line_w() function.
I will wait for fallout reports for a week or so,
then continue converting more libc_hidden_proto's.

No mass migration of libc_hidden_proto(foo) planned.

The attached patch adds support for compiling arm uClibc as pure Thumb code.
This is needed because some recent ARM codes do not implement traditional ARM
mode. Specifically:
* Cortex-M1 - An extremely minimal FPGA based core that only implements
Thumb-1 (aka ARMv6-M).
* Cortex-M3 - A Thumb-2 only ARMv7-M core.
Most of uClibc already builds in Thumb mode, all that is left are a handful of
assembly bits.
Tested on arm-uclinuxeabi.
