This patch makes sufficient modifications to the SH sys/user.h to be
able to build and run gdbserver with Linux kernel 2.6.30.
The problem is that both the kernel and library headers define the same
symbols, thus making it impossible in include both headers. The patch
undefines the kernel symbols in favour of the library symbols.

Make sure we declare the error properly in case a port uses it, and fix the
invocation of exit(). Since clone() will be returning a pid, assume that
the value will not have the MSB set (negative) to simplify the error test a
bit more. If gcc supports it, force this function to always be heavily
optimized in a bid to avoid stack usage as much as possible.

The fstatat() syscall is a little funky in that it sometimes changes name
between 32 and 64 bit hosts, but it should always operate on a 64bit stat
structure. So for the fstatat() function, make sure we convert it from a
64bit kstat to a 32bit stat.
Along these lines, we need to restore the __xstat32_conv() function.

The xstatconv.h header already sets up hidden prototypes for us, so no

This reverts commit b1913a876059949e6c309bafade55e9425ef33fb.
OABI is still a requirement. So we override the common syscall
implementation specifically for arm port.

In any non-buggy program free() does not fail.
And when it fails in a buggy program, the failure
is usually fatal (heap corruption and segfault).

bug #1:
static_fd = -1;
close(static_fd);
DOH!
bug #2:
if (utmp_fd == -1) {
__setutent();
}
if (utmp_fd == -1) {
return NULL;
}
if utmp_fd == -1, we call _setutent().
if __setutent() opens a fd, utmp_fd (a parameter)
wouldn't change, the second check is bogus.
We need to use static_fd instead in second check.
Which makes clear that having utmp_fd parameter
is wrong. See the patch for a complete fix.
Shrink comes from simplifying fcntl(static_fd, F_SETFD, FD_CLOEXEC):

CLONE_VM (used in no-MMU daemon) is defined in <bits/sched.h>. A
build with threads ends up including <sched.h> via <pthread.h> via
<bits/uClibc_mutex.h>; this indirect include does not happen for a
build without threads, so this patch adds a direct <sched.h> include.

Fill out the stat structure so that the nanosecond resolution support is
always available. There is a small code size increase for a few ports
(three additional assignments in xstatconv), but otherwise everything
should remain the same.
While we're here, punt __old_kernel_stat from the few headers that still
define it as it is unused in uClibc and causes compile errors after these
nanosecond changes.

The sbrk() function can be used to merely query sizes and for that, no-mmu
works the same as mmu. It can also sometimes increase data segments on
no-mmu systems provided the trailing memory is free. So, there is no real
reason to exclude this function for no-mmu ports.

The order of attributes in a function definition matters and in a few
places in the Blackfin code, it was being applied to the return type
instead of the function itself.

Rather than force people to always implement their own vfork(), have the
default implementation be sane.
For now, only the Blackfin port uses the new code.
