Also add "make syntax-check" rules to ensure no new uses sneak in.

There are many uses of write like this:

    if (write (fd, xml, towrite) != towrite)
        return -1;

The problem is that the syscall can succeed, yet write less than
the requested number of bytes, so the caller should retry
rather than simply failing.

This patch changes most of them to use util.c's safewrite wrapper,
which encapsulates the process.  Also, there were a few cases in
which the retry loop was open-coded, and I replaced those, too.

Given code like: T *var = calloc (n, sizeof (T));
Convert to this: T *var = calloc (n, sizeof (*var));
This first-cut change adjusts all malloc, calloc, and
realloc statements.

The only binary differences are in remote_internal.c

before any macro that uses AC_COMPILE_IFELSE.
(AC_OUTPUT): Add lib/Makefile and gl-tests/Makefile.  Remove m4/Makefile.
* Makefile.am (SUBDIRS): Add gnulib/lib and remove m4.  Add gnulib/tests
early enough that those tests run before any libvirt unit tests.
* m4/Makefile.am: Remove file.  Not needed.

        Removed <ansidecl.h> - unused.
        Added a comment around __func__.
        Removed a clashing redefinition of VERSION symbol.
        All limits (PATH_MAX etc) now done in src/internal.h, so we
