lists: add list sorting routine
We need a list sorting function, just to mention one example user that could
benefit is the lib/tt code to sort columns.
This patch adds list_sort() which uses the Merge Sort algorithm, behaving
nicely in O(nlog(n)), heavily based on the kernel's implementation[1]. The
private data (void *priv) passed to the comparison function as been removed to
adopt a qsort(3)-like syntax, and IMHO we don't really need it anyways.

partx: don't print error when partition already doesn't exist
If you run partx -d to delete partitions, and there are gaps
in the sequence ( partition 2 exists, but 1 doesn't ), then it
would complain that it had errors trying to remove the partitions
that already don't exist. Changed to ignore the error when
errno == ENXIO.

agetty: don't use log_err() for non-fatal errors
The TIOCSCTTY ioctl requires that caller is session leader -- so it
depends on initd (or we have to add setsid() to aggety). It seems that the
traditional way is to setup tty in agetty and session in login(1).
It means that all session related things (TIOCSCTTY, vhangup, ...) in the
command agetty should be optional. (Note that vhangup() is called when
--hangup is explicitly specified on command line, so log_err() makes
sense there.)

small bug in mkfs.cramfs + patch
mkfs.cramfs on version v2.17.2 has a small bug when dealing with very small
filesystems. look at upstream code on git, and the issue is still here.
ex:
$ cd /tmp
$ mkdir content
$ echo hello > content/a
$ echo hello > content/b
$ mkfs.cramfs content content.cramfs
not enough space allocated for ROM image (4090 allocated, 4096 used)
Here is a patch for fixing (simply rounding to page size AFTER eleminating
doubles).

Signed-off-by: Bernhard Voelker <mail@bernhard-voelker.de>
The lock file cannot be opened in read-write mode by default, because
then we cannot use flock(1) to lock executable files.
The read-write mode for lock files is necessary on NFSv4 where
flock(2) is emulated by by fcntl() -- this situation is possible to
detect by flock(2) EIO error.
This patch reverts the default to O_RDONLY and use O_RDWR only if EIO
error is detected.

This allows the creation of a new label if the disk already has an existing
