95rootfs-block would not terminate the commandline parameter with
a space or newline, instead it'll rely on the main routine from
dracut.sh to do this.
Which will cause unexpected problems for any modules called
after this.
So terminate the commandline parameters correctly here and remove
the newline from dracut.sh.

If there's a root fallback, at least attempt to have it falling
back to the last root filesystem this system ran off of.

cmdline_journal does not contain linefeeds anymore, so read
silently skipped it altogether.

--hostonly-cmdline:
Store kernel command line arguments needed in the initramfs
--no-hostonly-cmdline:
Do not store kernel command line arguments needed in the initramfs
--persistent-policy <policy>:
Use <policy> to address disks and partitions.
<policy> can be any directory name found in /dev/disk.
E.g. "by-uuid", "by-label"
This prints the kernel command line parameters for the current disk
layout.

In the kernel comments PARTUUID is shown using uppercase A-F:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/init/do_mounts.c?id=HEAD#n183
However, dracut tries to use the value of PARTUUID directly in
/dev/disks/by-partuuid/ which expects the hex to be lowercase. This will
cause root to never be found, oops!
Fix dracut so it can, like the Kernel, accept either casing.
Untested but I added a hack on my local system that was similar.
xfs and reiserfs (among other) supports storing journal data to a
separate device. Unfortunately, XFS requires this information to boot
properly (reiserfs can embed the information in its metadata but you
might want to override it).

To not pollute dracut-lib.sh, all the fsck related functions were moved
to fs-lib.sh. The functions available are as follows:
- fsck_single
this will detect/verify filesystem, check if it has necessary tools and
check the filesystem respecting additional flags (if any), using
specific "driver" (or falling back to generic one). Currently
available: fsck_drv_{com,xfs,std}. 'com' is used for tools following
typical subset of options/return codes (e.g. ext, jfs), 'std' is used
for "unknown" fs and doesn't assume it can be run non-interactively.
Please see comments around the code for more info.
- fsck_batch
this will check provided list of the devices;
Both of the above functions will fake empty fstab, to make generic fsck
not complain too much (excact devices are always provided on the command
line).
"Known" filesystems currently: ext234, reiser, jfs, xfs
- det_fs
Small bug fixed - as this function is meant to be called in $(), it may
not be verbose.
Current behaviour is:
- if detection is successful, use its result
- if detection is not successful, and filesystem is provided, return
the provided one; otherwise use auto
