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
(due to the bug fix) and in xmlrpc.c (due to factorization).

* python/libvir.c: As above.
* qemud/event.c: Likewise.
* qemud/mdns.c: Likewise.
* qemud/qemud.c: Likewise.
* qemud/remote.c: Likewise.
* src/bridge.c: Likewise.
* src/buf.c: Likewise.
* src/conf.c: Likewise.
* src/hash.c: Likewise.

* src/xen_unified.c: Likewise.
* src/xm_internal.c: Likewise.
* src/xml.c: Likewise.
* tests/qemuxml2argvtest.c: Likewise.
* src/xmlrpc.c (xmlRpcValuePtr): Likewise, and minor factorization.
* src/remote_internal.c (remoteAuthMakeCredentials): Use the right
type when allocating space for an array of cred _pointers_.

New files go into these directories:
  gnulib/lib
  gnulib/m4
  gnulib/tests

* bootstrap: A wrapper around gnulib-tool.
* configure.in: Invoke gl_EARLY and gl_INIT, being careful to put gl_EARLY
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.
* src/Makefile.am (INCLUDES): Add -I$(top_srcdir)/gnulib/lib -I../gnulib/lib.
(LDADDS, libvirt_la_LIBADD): Add ../gnulib/lib/libgnu.la.
* src/nodeinfo.c: Include "physmem.h".
* qemud/qemud.c, src/remote_internal.c: Include "getaddrinfo.h".
(MEMINFO_PATH, linuxNodeInfoMemPopulate): Remove definitions.
(virNodeInfoPopulate): Use physmem_total, not linuxNodeInfoMemPopulate.
* tests/Makefile.am (INCLUDES): Add -I$(top_srcdir)/gnulib/lib -I../gnulib/lib.
(LDADDS): Add ../gnulib/lib/libgnu.la.
* qemud/Makefile.am (libvirtd_LDADD): Add ../gnulib/lib/libgnu.la.
* tests/nodeinfotest.c (linuxTestCompareFiles): No longer read total
memory from a file.
Update expected output not to include "Memory: NNNN"
* tests/nodeinfodata/linux-nodeinfo-1.txt:
* tests/nodeinfodata/linux-nodeinfo-2.txt:
* tests/nodeinfodata/linux-nodeinfo-3.txt:
* tests/nodeinfodata/linux-nodeinfo-4.txt:
* tests/nodeinfodata/linux-nodeinfo-5.txt:
* tests/nodeinfodata/linux-nodeinfo-6.txt:
* src/test.c [WITH_TEST]: Remove definition of _GNU_SOURCE that
would conflict with the one now in "config.h".
* autogen.sh: Add -I gnulib/m4.
* src/conf.c, src/sexpr.c: Don't define _GNU_SOURCE.
Instead, include "config.h".
* qemud/qemud.c: Remove definition of _GNU_SOURCE.
* src/openvz_driver.c: Likewise.
* src/qemu_driver.c: Likewise.
* src/remote_internal.c: Likewise.

* configure.in: Use AC_CONFIG_AUX_DIR(build-aux), so that a bunch
of gettextize-generated files go into build-aux/, rather than in
the top-level directory.
* .cvsignore: Adjust.
* build-aux/.cvsignore: New file.

* tests/conftest.c: Use fwrite, not printf, since the
  result buffer is not NUL-terminatedi, from Jim Meyering.

  qemudBuildCommandLinei, from Jim Meyering.

  src/virsh.c src/xm_internal.c: change malloc/memset(0) pairs to

        Note: potential ABI break here, but people should
        only really be using virError structs returned from
        libvirt itself.

        * include/libvirt/virterror.h: add virNetwork
        to virError

        * src/internal.h, src/virterror.c: add network param
        to __virRaiseError()

        * src/conf.c, src/hash.c, src/libvirt.c, src/proxy_internal.c,
        src/qemu_internal.c, src/sexpr.c, src/test.c, src/xen_internal.c,
        src/xend_internal.c, src/xm_internal.c, src/xml.c, src/xmlrpc.c,
        src/xs_internal.c: update.
