It some cases it makes sense to disable ECHO flag also when script
used in pipe. This new option allows to keep full control in user's
hands.

We need a proper way how to inform child (shell) that the game is
over. It seems the best is to send EOF to child rather than
immediately break PTY mainloop where we have poll(), because shell can
still produce data etc.

For tools like su(1) is ECHO flag unexpected for use-case like
echo 'date' | su - user
but script(1) need the echo to keep input recorded.
The patch also return execlp() use to script(1) code.

nologin is typically used in /etc/passwd as a shell replacement. Hence it
is reasonable to ignore well known command-line options silently to avoid
unwanted ugly error messages.

libfdisk chooses a grain of 1MB fairly arbitrarily, and this granule
may not be honored by other utilities. GPT disks formatted elsewhere
may have space before the first partition, AND a partition that exists
solely below 1MB. If this occurs, cfdisk ends up adding a free space
region where end < start, resulting in a 16 Exabyte free region.
That's too many exabytes.
This happens because the start gets rounded up to the granule size in
new_freespace() but the end is left alone. The logs show it best:
23274: libfdisk: CXT: [0x572d878]: initialized: last=34, grain=2048
23274: libfdisk: CXT: [0x572d878]: partno=10, start=64

23274: libfdisk: CXT: [0x572d878]: LBA 34 aligned-near 0 [grain=2048s]
23274: libfdisk: CXT: [0x572d878]: 0 in range <2048..0> aligned to 2048

Avoid this by aligning the last value like new_freespace() does.

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

For example:

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.
