Borrow ideas from gnulib/build-aux/bootstrap, in order to factor the
specifics of libvirt into bootstrap.conf, while allowing future
upgrades of bootstrap to happen with less effort.

* bootstrap (gnulib_tool): Update invocation to be closer to
gnulib's version.  Move libvirt specifics...
* bootstrap.conf: ...into new file.

* src/util/storage_file.c: Include "dirname.h".
(absolutePathFromBaseFile): Rewrite not to leak, and to require
fewer allocations.
* bootstrap (modules): Add dirname-lgpl.
* .gnulib: Update submodule to the latest.

it causes a NULL-dereference on some systems like Solaris 10.
* src/node_device/node_device_linux_sysfs.c. Include <stdlib.h>.
(get_sriov_function): Use canonicalize_file_name, not realpath.
* bootstrap (modules): Add canonicalize-lgpl.

* src/util/logging.c (virLogMessage): Include "ignore-value.h".
Use it to ignore the return value of safewrite.
Use STDERR_FILENO, rather than "2".
* bootstrap (modules): Add ignore-value.
* gnulib: Update to latest, for ignore-value that is now LGPLv2+.

The virFileResolveLink utility function relied on the POSIX guarantee
that stat.st_size of a symlink is the length of the value.  However,
on some types of file systems, it is invalid, so do not rely on it.
Use gnulib's areadlink module instead.
* bootstrap (modules): Add areadlink.
* src/util/util.c: Include "areadlink.h".
Let areadlink perform the readlink and malloc.
* configure.in (AC_CHECK_FUNCS): Remove readlink.  No need,
since it's presence is guaranteed by gnulib.

This implementation stores the secrets in an unencrypted text file,
for simplicity in implementation and debugging.

(Symmetric encryption, e.g. using gpgme, will not be difficult to add.
Because the TLS private key used by libvirtd is stored unencrypted,
encrypting the secrets file does not currently provide much additional
security.)

* include/libvirt/virterror.h, src/virterror.c (VIR_ERR_NO_SECRET): New
  error number.
* po/POTFILES.in, src/Makefile.am: Add secret_driver.
* bootstrap: Use gnulib's base64 module.
* src/secret_driver.c, src.secret_driver.h, src/libvirt_private.syms:
  Add local secret driver.
* qemud/qemud.c (qemudInitialize): Use the local secret driver.

* src/openvz_conf.c (openvzReadNetworkConf): Replace open-coded
while loop with equivalent use of strchrnul.
* bootstrap (modules): Add strchrnul.

* README-hacking: New file.
* bootstrap: Remove obsolete comments.

No longer maintain a version-controlled ChangeLog file, but do
continue to include a ChangeLog file in distribution tarball.
* Makefile.am (gen-ChangeLog): New rule.
(dist-hook): Depend on it.
(EXTRA_DIST): Add ChangeLog-old.
* bootstrap (modules): Add gitlog-to-changelog.
* ChangeLog: Remove file.  Renamed to...
* ChangeLog-old: ...this.  New file.
* autogen.sh: Touch ChangeLog, to ensure it exists.  For automake.

* 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.

This makes it so we record (via a git submodule)
a snapshot of whatever version of gnulib we're using,
and none of gnulib sources are in the libvirt repository.
The result is that we have as much reproducibility as when
we version-controlled imported copies of the gnulib sources,
but without the hassle of the manual process we used when
syncing with upstream.

Note that when you clone libvirt, you get only the libvirt
repository, but when you first run ./bootstrap, it clones
gnulib (at the SHA1 recorded via the submodule), creating
the .gnulib/ hierarchy.  Then, the bootstrap script runs
gnulib-tool to populate gnulib/ with the files that make
up the selected modules.

Put the following in your ~/.gitconfig file.
[alias]
  syncsub = submodule foreach git pull origin master

The update procedure is simple:
  git syncsub
  ...build & test...
  git commit -m 'gnulib: sync submodule to latest' .gnulib

* .gitmodules: New file.
* .gnulib: Initialize.
* bootstrap: Set up to use the new submodule.
Stop using --no-vc-files.
Don't remove .gitignore files.
Don't use or create .cvsignore.
Diagnose an invalid --gnulib-srcdir=DIR argument.
* build-aux/vc-list-files: Delete file, now pulled from gnulib.
* build-aux/useless-if-before-free: Likewise.
* po/POTFILES.in: Remove gnulib/lib/gai_strerror.c, since
it no longer contains translatable strings.
* gnulib/*: Remove gnulib/ hierarchy.

* gnulib/lib/stpcpy.c: New file.
* gnulib/m4/stpcpy.m4: New file.
* gnulib/lib/Makefile.am: Update.
* gnulib/m4/gnulib-cache.m4: Update.

option, since we version-control the files it imports.
