03d777f345 Introduce virStrncpy.
Add the virStrncpy function, which takes a dst string, source string,
the number of bytes to copy and the number of bytes available in the
dest string.  If the source string is too large to fit into the
destination string, including the \0 byte, then no data is copied and
the function returns NULL.  Otherwise, this function copies n bytes
from source into dst, including the \0, and returns a pointer to the
dst string.  This function is intended to replace all unsafe uses
of strncpy in the code base, since strncpy does *not* guarantee that
the buffer terminates with a \0.

8f84fef2eb build: submodule machinery now works also when no tag is reachable
The code in cfg.mk to detect when the git submodule was out of date
worked most of the time, but not when checked out in a certain way.
* cfg.mk: Extract submodule hash from command output and file,
and compare only that, since the format of the full line may vary.
Reported by Mike Burns, with some diagnosis by Daniel P Berrange.

08a2e796e8 make "make syntax-check" consistent with "git diff --check"
This makes "make syntax-check" fail when a version-controlled
file contains a trailing blank line.
* cfg.mk (sc_prohibit_trailing_blank_lines): New rule.

f272378d52 build: automatically rerun ./bootstrap when needed
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* cfg.mk: Diagnose out of date submodule and fail.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.

bf773e0467 use gnumakefile and maintainer-makefile modules from gnulib
* 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.

360194bfb5 skip some of gnulib's new rules
* cfg.mk (local-checks-to-skip): Add these: sc_error_message_uppercase,
sc_program_name, sc_require_test_exit_idiom, sc_makefile_check.

c120fcc06a Prepare to use maint.mk from gnulib
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
