The current situation is that distros differentiate between:
* host specific configuration -- usually /etc, maintained by admin
* distribution specific (static) configuration -- usually /usr/lib,
maintained by ditro packages
Unfortunately autotools have clue about $sysconfdir (/etc) only. This
patch introduces $sysconfstaticdir (default $prefix/lib).

The parse-date.y is used only for hwclock, let's keep it together.
Note that the file (originally from gnulib) has GPLv3 license, so it's
better to make it obvious that we use it really only for hwclock (also
GPL).

When autoclose is set (kernel default but many distributions reverse the
setting) opening a CD-rom device causes the tray to close.
The function of blkid is to report the current state of the device and
not to change it. Hence it should use O_NONBLOCK when opening the
device to avoid closing a CD-rom tray.
blkid is used liberally in scripts so it can potentially interfere with
the user operating the CD-rom hardware.
[kzak@redhat.com: add O_NONBLOCK also to:
- wipefs
- blkid_new_probe_from_filename()
- blkid_evaluate_tag()]

Since 34333e5244 we apply fstab options
manually by mnt_context_apply_fs() on --all. The function does not
work correctly when optsmode is zero.

For example:
# mount --verbose --all -t xfs -o ro
will mount all all XFS filesystems from fstab, but read-only.

The current implementation works, but the remount operation is done in
the cloned context and the original context (and calling application)
has no information about the final status/errors. This is mistake.
This new implementation works like mnt_context_next_mount(), it means
the same context (as used by application) is reused for all remounts.
The original setting is restored by mnt_context_apply_template().

This commit adds new functions to save and reuse the current FS
setting (mount options from command line, etc) after context reset.
It's usable for example in "mount --all" when we use the same context
for more times for more mount operations.

The current solution is to use /proc/mounts if previous attempt to
open /proc/self/mountinfo failed. The fallback should not be used when
mount table path is explicitly specified by application. The default
is NULL, only in this case libmount should be try to be smart.

In commit b1418ed14 (lib/path: add ul_path_stat(), fix absolute paths,
2019-10-15), a new function `ul_path_stat()` was added to "path.h". This
new function prototype causes a compiler warning on musl libc based
systems due to one of the parameters having the unknown type `struct
stat` due to the <sys/stat.h> header not being included.
Fix the warning by including the header.

The classic way which is based on file-descriptors table size is
pretty expensive (due to table size) and forces code to do many
unnecessary close() calls. It seems better to use /proc/self/fds and
close used descriptors only.

The option --sysroot is used to read information from dumps rather
than from the current system. This patch allows to read also udev

* add ul_path_stat()
* make sure all paths for ul_path_..() functions are always
interpreted relatively to the context directory and prefix. This is
difference between ul_path_ API and standard libc "at" functions. We
do not use any exception for absolute paths. The reason is that we
need to read from prefixed paths although application assume absolute
path (/dev/sda1 means /prefix/dev/sda1 if a /prefix is defined).

Currently if `--disable-all-packages` is set, there is no configure
option for re-enabling `wipefs`.
As the current default for `wipefs` is "enabled", add `--disable-` flag
