Guard against duplicate inclusion.
We should go back to just including the linux/sysinfo.h ..

508b20ead1710e8c295630d096960e51a65b7e5d disentangled
program_invocation_name and __progname but forgot to make __progname
conditional on __UCLIBC_HAS___PROGNAME__, resulting in getconf
attempting to re-define __progname in case __UCLIBC_HAS___PROGNAME__ was
not defined.

A simple statically linked hello world program was segfaulting for ARC
in linuxthreads.old configuration (although the root casue applies
cross-arch for NPTL as well as linuxthreads.old as described)
The crash was due to branch to NULL in _stdio_init
0001026c <_stdio_init>:
1026c: push_s blink
1026e: st.a r13,[sp,-8]
10272: bl.d 0 --> supposed call to __errno_location
The call was NOT getting patched to libc internal only alias
__GI___errno_location, because it was weak while it's exported cousin,
__errno_location was strong/normal.
arc-linux-uclibc-nm libc/misc/internals/__errno_location.os
00000000 W __GI___errno_location
00000000 T __errno_location
This is exactly opposite to what is expected.
Quoting Peter S. Mazinger, commit 87936cd013041 "errno and *_init cleanup"
| The rule adopted:
| for enabled threads we make in libc the __GI_x() variants strong, x() weak
| and (should) provide another strong x() in libpthread.
| If threads are disabled, even the __GI_x() variants are weak.
With the fix, we see the right settings as below
00000000 T __GI___errno_location
00000000 W __errno_location
Note that problem won't show up in a static busybox build as it references
errno and that seems to elide the issue.
I can confirm the same/more issues with latest ARM buildroot builds w/o
my fix.
(1). linuxthreads.old (broken just like ARC)
arm-linux-nm uclibc-snapshot/libc/misc/internals/__errno_location.os
00000000 W __GI___errno_location
00000000 T __errno_location
But presumably the issue there is NOT catestrophic because ARM linker is
likely smarter and patches a NOP instead of NULL branch.
00008388 <_stdio_init>:
8388: e92d4038 push {r3, r4, r5, lr}
838c: e320f000 nop {0}
(2) NPTL build (exported version is not weak)
00000000 T __GI___errno_location
00000000 T __errno_location
This causes a static link with libpthread and test program
referencing errno to fail to link.
#include <errno.h>
int main(void)
{
printf("%d\n", errno);
}
arm-linux-gcc -static -pthread -o tst tst.o
arm-buildroot-linux-uclibcgnueabi/sysroot/usr/lib/libc.a(__errno_location.os):
In function `__errno_location': __errno_location.c:(.text+0x0):

This adds a straight forward implementation for obstack_printf and
obstack_vprintf on uClibc's already existing obstack_grow and
vasprintf. It does not attempt to port over glibc's implementation
in terms of _IO_* structs and functions.

Partially reverts "parser_config.[ch]: remove duplicated hidden functions"
There's a namespace collision for config_{open,close,read} functions
between uClibc and Busybox. Callers in uClibc and busybox need to call
their local variants. In case of static linking, both the variants need
to be pulled in the final executable.
Turns out that the existing hidden attribute is not enough for static
linked Busybox where the linker treats these symbols as duplicate and
pulls in only the local (Busybox's own) variants in the final link.
This obviously causes the uClibc callers to crap out at runtime.
This can be fixed by restoring the libc_hidden_proto() annotation
which causes the libc variants to be aliased with __GI_ prefix thus
making both the symbols distinct from linker's perspective.
This issue was found with ARC gcc 4.8 + uClibc trunk.
I can confirm the same thing with ARM uClibc buildroot build (when
switching to uClibc daily snapshot).
All the credit for debugging the issue goes to Anton,Joern and Jeremy -
I simply found the cure :-)

This drops __signed, __volatile, and __const. Only the latter was
used in the code base, and for uClibc, not consistently. Much of
the code used plain "const" which meant "__const" was useless.
Really, the point of this is to stay in sync with what glibc did.

sigtimedwait:
- provide __sigtimedwait_nocancel
- use __SYSCALL_SIGSET_T_SIZE instead of _NSIG / 8
- do not provide __sigtimedwait
- guard a section to avoid failure on archs if SI_TKILL/SI_USER are not defined
sigwaitinfo:
- simply use sigtimedwait since that handles cancellation already
sigwait:
- use non-cancellable functions (sigtimedwait, sigsuspend)
