* lib/mountlist.c (read_file_system_list): Parse /proc/self/mountinfo
directly, rather than depending on libmount, which has many
dependencies due to its dependence on libselinux, as detailed at:
http://lists.gnu.org/archive/html/bug-gnulib/2015-01/msg00063.html
Note we restrict this to __linux__ as that's probably where this
interface will remain. If ever porting, it would be best
to first pull the makedev() wrapper from coreutils to a gnulib module.
Note also we don't add a getline dependency to the mountlist module,
as all Linux versions are sufficient.
Use libmount to propagate device IDs provided by Linux in
/proc/self/mountinfo. This will give more accurate output when
using df in chroot'ed environments as the device IDs are not
determined by stat() which may be inaccurate within the chroot.
* lib/mountlist.c (read_file_system_list): Use the libmount routines
from util-linux to parse "/proc/self/mountinfo" or fall back to
standard getmntent() processing.
* m4/ls-mntd-fs.m4: Check for libmount only when 1-argument
getmntent() is used, as is the case on GNU/Linux.
* DEPENDENCIES: Mention the optional util-linux dependency.
Based on the bootstrap fallout in commit bb2f5640.
* doc/gnulib-tool.texi (gettextize and autopoint): Document the
choice between versions.
* DEPENDENCIES (gettext): Cover both approaches.

List tools needed by gnulib-tool, whether or not the project
also requires the tools in cfg.mk $buildreq. In particular,
detect if the project uses gnulib-local diffs, in which case
patch is a prerequisite.
* build-aux/bootstrap (buildreq): Provide minimum implicit
dependencies.
* DEPENDENCIES: Mention patch as a prereq.
