Back out yesterday's big merge from the libposix branch, except for the
openat-die.c change that was reviewed and approved by Paul Eggert.
Put the ChangeLog entry at the top, to reflect the order of changes in the
master branch.

they are not needed. Also, replace M4 macro prefixes when requested.
Finally, omit calls to error() for libposix.

Each *.in.h file serves two purposes - provide enough self-contained
content to serve as a replacement for the system header regardless of
the user's compiler, and offer the developer the ability to detect any
gnulib modules that might have been inadvertantly excluded. The
former requires independence from config.h, and routes everything
through a Makefile.am snippet that uses @@ substitution specific to
the modules that were in use, with details learned at configure time.
The latter works by poisoning anything that gnulib did not replace,
but which the developer had natively available, explaining why their
tests passed during development. Poisoning relies on gcc features,
and requires manual triggering by adding -DGNULIB_POSIXCHECK to
CFLAGS; it assumes that <config.h> is properly included. In fact, we
do not want to use @@ substitution for HAVE_DECL_* during poisoning,
because the warning is only relevant for the gnulib modules which were
not included, and thus where the m4 macros to set proper @@ values
have not been run. Furthermore, we only need to poison interfaces
that already have a declaration; if something is not declared, then
the developer wouldn't have been able to link, so their code won't be
using the problematic interface in the first place.
