    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

    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.

    Fix -Wundef warning for HAVE_OBSTACK

    Remove the HAVE_OBSTACK macro check and include obstack check in

    current directory.

    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.
