When "git pull" (or any other operation) brings in a new version of the
gnulib git submodule, you must rerun the autogen.sh script.  With this
change, "make" now fails and tells you to run ./autogen.sh, when needed.
* autogen.sh: Maintain a new file, .git-module-status, containing
the current submodule status.  If it doesn't exist or its content
is different from what "git submodule status" prints, then run
./bootstrap
* .gitignore: Add .git-module-status
* cfg.mk: Diagnose out of date submodule and fail.
* README-hacking: Update not to mention bootstrap.
* Makefile.am (MAINTAINERCLEANFILES): Add .git-module-status,
so that "make maintainerclean" will remove it.

* bootstrap (modules): Add gnumakefile and maintainer-makefile.
* GNUmakefile: Remove file, now provided by gnulib.
* Makefile.maint: Remove.  Replaced by maint.mk from gnulib.
.gitignore: Add GNUmakefile and maint.mk.
* cfg.mk (prev_version_file): Disable this feature.
Setting this to /dev/null avoids an otherwise harmless diagnostic.

* cfg.mk (local-checks-to-skip): Add these: sc_error_message_uppercase,
sc_program_name, sc_require_test_exit_idiom, sc_makefile_check.

Since Makefile.maint will soon come from gnulib's maint.mk,
sync Makefile.maint to have the same contents (modulo minor
things).  In syncing it, we have to remove some libvirt-specific
rules.  Since we want to keep them (of course), put those in cfg.mk.
* Makefile.maint: Merge from gnulib's maint.mk.
* cfg.mk (sc_avoid_write): New rule.  From Makefile.cfg.
(sc_prohibit_strcmp_and_strncmp): Likewise, and rename.
(sc_prohibit_asprintf, sc_prohibit_VIR_ERR_NO_MEMORY): Likewise.
(sc_prohibit_nonreentrant): Likewise.
(sc_prohibit_ctype_h): Likewise.
(sc_TAB_in_indentation, sc_avoid_ctype_macros): Likewise.
(sc_prohibit_virBufferAdd_with_string_literal): Likewise.
(sc_prohibit_gethostby): Likewise.
(sc_libvirt_unmarked_diagnostics): Likewise.  Also, rename the
rule, inserting "_libvirt", since this rule is a specialization of
the one in gnulib.
* GNUmakefile: Include cfg.mk, not Makefile.cfg
* .x-sc_prohibit_strcmp_and_strncmp: New file.
* Makefile.am (EXTRA_DIST): Add .x-sc_prohibit_strcmp_and_strncmp

* cfg.mk: ...this.  New file.

* Makefile.cfg (local-checks-to-skip): Remove sc_redundant_const.
* src/lxc_controller.c: Remove redundant "const"(s).
* src/storage_backend_fs.c: Likewise.
* src/util.h: Likewise.
* src/xen_internal.c: Likewise.
* tests/qparamtest.c: Likewise.

* Makefile.cfg (local-checks-to-skip): Don't skip sc_m4_quote_check.
Don't skip sc_prohibit_nonreentrant.
* Makefile.nonreentrant (NON_REENTRANT): Comment out until we've
remove all remaining uses of strerror.

* Makefile.cfg (useless_free_options): Also check for VIR_FREE.
* src/iptables.c (iptRulesFree): Remove useless if-before-VIR_FREE.
* src/remote_internal.c (remoteAuthSASL): Likewise.
* src/test.c (testOpenFromFile): Likewise.

* Makefile.cfg (useless_free_options): Add --name=xmlFree.

* Makefile.maint (sc_changelog): Adapt to work with legacy
ChangeLog entry header lines.
* Makefile.cfg (local-checks-to-skip): Remove sc_changelog.

* Makefile.cfg (local-checks-to-skip): Remove sc_no_have_config_h.
* qemud/mdns.c: Remove "#ifdef HAVE_CONFIG_H".
* Makefile.maint (sc_no_have_config_h): Tighten up regexp,
so that the above mention of "HAVE_CONFIG_H" doesn't match.
* .x-sc_no_have_config_h: New file, to exempt gnulib/ straggler.

* build-aux/useless-if-before-free: Rename from ...
* build-aux/find-unnecessary-if-before-free: ... this.  Remove file.
Also changed it so that new names are no longer hard-coded in the
script.  Instead, they're supplied via options:
* Makefile.cfg (useless_free_options): Define.
Add xmlXPathFreeObject to the list of free-like functions it detects.
* Makefile.maint (sc_avoid_if_before_free): Reflect script renaming.
* .x-sc_avoid_if_before_free: Likewise.
* src/openvz_conf.c (openvzParseXML): Remove useless "if"-before-free.
* src/qemu_conf.c (qemudParseXML, qemudParseNetworkXML): Likewise.
* src/virsh.c (cmdVNCDisplay, cmdTTYConsole, cmdDetachInterface):
(cmdDetachDisk): Likewise.
* src/xm_internal.c (xenXMConfigSetIntFromXPath): Likewise.
(xenXMConfigSetStringFromXPath, xenXMParseXMLToConfig): Likewise.
(xenXMDomainAttachDevice, xenXMAttachDisk, xenXMAttachInterface):
(xenXMDomainDetachDevice): Likewise.
* src/xml.c (virXPathString): Likewise.
* tests/xmlrpctest.c (checkRequestValue): Likewise.

* Makefile.cfg (local-checks-to-skip): Remove sc_trailing_blank.
* .x-sc_trailing_blank: New file, to exempt the few binary files.

involving the "error" function.
* Makefile.cfg (local-checks-to-skip): Remove from skip list.
* src/remote_internal.c: Mark translatable strings.

* Makefile.cfg (local-checks-to-skip) [po-check]: Enable.
* po/POTFILES.in: Add three file names.  Sort.

Use <config.h>, not "config.h", per autoconf documentation.
