Dracut: Add a new argument "--rebuild"
Add "rebuild" option to dracut to append the current arguments
to those with which the input initramfs image was built. This
option helps in incrementally building initramfs for testing.
Usage: dracut [output_file] --rebuild input_file
If optional output file is not provided, input file provided to
rebuild will be used as output file.
This patch alters the creation of the initramfs image by adding
the file "/tmp/params.txt" to the image. Command line parameters
excluding "--rebuild", input & output image names and "kernel
version" are stored in this file. In case "--rebuild" parameter
is specified, "/tmp/params.txt" file, if present in input image,
is read and its contents "prepend"ed to the current command line
parameters, that is if such a file is already present. Also, it
stores the cumulative parameters to the file "/tmp/params.txt",
in the new image. This patch has been tested successfully on a
PowerBox with f19. It does not alter the behaviour of any of the
existing options.

crypt: Prevent asking for password multiple times if non-default crypt name is used.
If a non-default device mapper name is used for an encrypted partion is
used, (i.e. not luks-$UUID) due to parsing of /etc/crypttab, then the
short-circuits put in place to prevent asking the password twice do not
work.
This would not normally be an issue as the settled job itself should be
removed after it has run and thus cannot be run again. Sadly, due to
the corresponding udev rule using ACTION="add|changed", and the fact
that trying to unlock the device (whether successful or not) seems to
trigger a changed event, it means the settled job is recreated with
each itteration thus causing the whole loop to run again.
It is this situation that the short-circuit exits would normally come
into play but sadly do not work when non-standard names are used.
By the time the /tmp/cryptroot-asked-$2 file is written near the end of
the script, the value of $2 has already been lost due to the argument
parsing code's use of 'shift'. So while on systems where the default
name is used are protected by checking /dev/mapper/xxxx, the
/tmp/cryptroot-asked-$2 file didn't help on systems where this was not
used due to this bug.
So this commit shuffles things around somewhat such that:
1. The /dev/mapper/xxxx device is checked *after* resolving $2 (which
contains the default name) to whatever /etc/crypttab specifies.
2. The cryptroot-asked-xxxx file also uses the translated name both
for the initial check and to flag when it's written.
As a separate fix, it might make sense to change the udev rule to only
act on add events rather than add|change events, but I'm not sure of the
ramifications of such a change and there may be cases where the add
event is missed and thus the change event needs to be included.

lvm: do not run pvscan for lvmetad update
The lvmetad daemon is not yet running in initramfs so there's no
need to run pvscan (or instantiate any lvm2-pvscan systemd service).
If pvscan was called in this case (either directly or via systemd
instantiated service), it would fail because there's no lvmetad
daemon to update. This could cause confusion, especially in systemd
instantiated service which is run only once!

dracut-functions.sh: Avoid loading unnecessary 32-bit libraries for 64-bit initrds
Due to the 'inst_libdir_file "libnss_files*"' in the udev-rules module
this caues the /usr/lib/libnss_files-2.18.so* to be included. This is a
32-bit library and pulls in a 32-bit version of glibc also even on a
64-bit system.
This is due to the fact that ldconfig -pN will print [/usr]/lib paths
from the cache as well as [/usr]/lib64. As we handle these paths
specifically we should ignore these results from the cache.
Also there was a missing space when appending the ldconfig paths
onto our list meaning the last builtin and first ldconfig path
were unusable.

lvm: fix thin recognition
The global var setting was happening in a pipe and did not have an
effect.
Use <<<$() instead.
< <() cannot be used, because dracut is called in chroot's environments,
where /dev/fd does not point to /proc/self/fd, but bash wants
/dev/fd/<num> for this construct.

Add lzo, lz4 compression and read INITRD_COMPRESS
This patch adds support for lzop(1) & lz4(1) compression
algorithms to compress iniramfs image file. Both are supported
by the Linux kernel.
Linux kernel exports user's choice of initramfs compression
algorithm as a shell environment variable: INITRD_COMPRESS.
This patch adds support to read this variable and duly compress
the initramfs image file.
Environment variable INITRD_COMPRESS has less precedence than the
command line options --gzip, etc. Ie. command line options could
override the compression algorithm defined by $INITRD_COMPRESS.

libvolume_id thing and host_fs_types is populated using blkid.
