Fix crash when system has no ipv6 address [BZ #17125]

Here's an updated patch to fix the crash in bug-ga2 when the system
has no configured ipv6 address.  I have taken a different approach of
using libc_freeres_fn instead of the libc_freeres_ptr since the former
gives better control over what is freed; we need that since cache may
or may not be allocated using malloc.

Verified that bug-ga2 works correctly in both cases and does not have
memory leaks in either of them.
Fix -Wundef warning for HAVE_OBSTACK

Remove the HAVE_OBSTACK macro check and include obstack check in
include path order since we don't have a copy of obstack.h in the
current directory.
Fix -Wundef warning for HAVE_SYS_PARAM_H

Include sys/param.h unconditionally
Fix Wundef warning for HAVE_STRFTIME

Define it to 0
Fix -Wundef warning for HAVE_LOCALTIME_R

Define it to 0.  There is a gnulib copy for this, but it is out of
sync with our copy.
Sync up error.c with gnulib

Summary of changes:

- Use of !_LIBC instead of HAVE_CONFIG_H
- Code changes in [!_LIBC] that don't affect us
- Minor formatting changes
- Use __builtin_expect in shared code
- Define some macros in [_LIBC] that are used in gnulib but never
  defined in glibc
- Flip macro check for STRERROR_R_CHAR_P so that it does not throw a
  warning

PowerPC: Fix build due missing lll_robust_trylock

Commit 887865f remove the lll_robust_trylock definition on all
architectures, however for powerpc both __lll_trylock and
__lll_cond_trylock were based on lll_robust_trylock definition.
This patch restore it with a different name.
