* m4/wtmpdb.m4: New file.
* m4/readutmp.m4 (gl_READUTMP): Invoke gl_WTMPDB_CHOICE. Define
READUTMP_USE_WTMPDB. Take it into account for READUTMP_LIB.
* lib/readutmp.h (WTMPDB_FILE): New macro.
* lib/readutmp.c: Include <wtmpdb.h>.
(wtmpdb_time_to_timespec): New function.
(struct wtmpdb_locals): New type.
(wtmpdb_callback, read_utmp_from_wtmpdb): New functions.
(read_utmp): For WTMP_FILE, conditionally use read_utmp_from_wtmpdb.
* modules/readutmp (Files): Add m4/wtmpdb.m4.
(Depends-on): Add str_endswith.
* DEPENDENCIES: Mention libwtmpdb.
* lib/stdlib.in.h (print_stack_trace): Make part of the stack-trace
module.
* lib/stack-trace-impl.h: New file, based on lib/abort-debug.c.
* lib/stack-trace.c: New file, based on lib/abort-debug.c.
* lib/abort-debug.c: Include stack-trace-impl.h. Remove definitions
moved to stack-trace-impl.h.
(print_stack_trace): Remove function.
* m4/stdlib_h.m4 (gl_STDLIB_H_REQUIRE_DEFAULTS): Initialize
GNULIB_STACK_TRACE.
(gl_STDLIB_H_DEFAULTS): Initialize CAN_PRINT_STACK_TRACE.
* m4/stack-trace.m4: New file, based on m4/abort-debug.m4.
* m4/abort-debug.m4 (gl_ABORT_DEBUG_EARLY): Remove macro.
(gl_ABORT_DEBUG): Require gl_STDLIB_H_DEFAULTS, gl_STACK_TRACE_EARLY.
Set REPLACE_ABORT here.
* modules/stdlib (Makefile.am): Substitute GNULIB_STACK_TRACE,
CAN_PRINT_STACK_TRACE.
* modules/stack-trace: New file.
* modules/abort-debug (Depends-on): Add stack-trace. Remove execinfo.
(configure.ac-early): Remove section.
* DEPENDENCIES: Update.
* DEPENDENCIES: Clarify that GNU make is only needed on OpenBSD and
Solaris. Mark GNU tar as optional, not recommended. Add note about
Solaris 10. Add a second section "Dependencies for building the imported
code". Document the needed locales.
* DEPENDENCIES: Require GCC >= 3.1. Tell where to find working GNU m4
tarballs. Mention awk. Point to pre-built packages for gettext, bison,
gperf, texinfo.
* 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.
