This patch fixes a handful of ${#VAR[@]} tests, which can't be evaluated
as text expressions - the results is always true in such case, because
"0" is non-empty string.

-v meaning has changed. Now it increases verbosity level. -q option has
been added, which decreases verbosity level. Both options might be
specified multiple times.
As mentioned in kernel/Documentation/xz.txt:
...
Notes on compression options
Since the XZ Embedded supports only streams with no integrity check
or CRC32, make sure that you don't use some other integrity check
type when encoding files that are supposed to be decoded by the
kernel. With liblzma, you need to use either LZMA_CHECK_NONE or
LZMA_CHECK_CRC32 when encoding. With the xz command line tool, use
--check=none or --check=crc32.
Using CRC32 is strongly recommended unless there is some other layer
which will verify the integrity of the uncompressed data anyway.

Moved dlog() to _do_dlog() and created dlog() which reads from stdin if
no arguments (except the loglevel) are given.
This enables e.g.:
dwarn "This is a warning!"
echo "This is a warning!" | dwarn
It's dash compatible to be used also at boot-time. For now it's included
by dracut-functions and replaces functions: dinfo(), dwarning() and
derror(). New options are introduced: -L|--stdlog, and -q|--quiet to
control stderr verbosity. Logging to file or syslog may be controlled by
options set in config file.
Note that code is not adjusted to the meaning of the new logging
functions, yet.
Doxygen formatted documentation (as a proposal, by the way) is included
in dracut-logger.
Every image gets handled the same way regardless of filesystem, so
let's use a filesystem-neutral name (rather than adding new
lines for every fstype anyone might want to use).
Otherwise there is no way to skip pasword prompt. --has-active-vt
seems to correctly catch also the case when plymouthd is started
but splash is disabled.

These parameters can now be specified multiple times:
-a|--add
--add-drivers
-m|--modules
-o|--omit
-d|--drivers
--filesystems
-I|--install
--fwdir
-i|--include
This adds the following parameters:
rd.caps=1
turn the caps module on/off
rd.caps.initdrop=cap_sys_module,cap_sys_rawio
drop the specified comma seperated capabilities
rd.caps.disablemodules=1
turn off module loading
rd.caps.disablekexec=1
turn off the kexec functionality
If module loading is turned off, all modules have to be loaded in the
initramfs, which are used later on. This can be done with
"rd.driver.pre="
rd.driver.pre=autofs4,sunrpc,ipt_REJECT,nf_conntrack_ipv4,....
Because the kernel command line would get huge with all those drivers, I
recommend to make use of $initramfs/etc/cmdline.
So, all rd.caps.* and rd.driver.pre arguments are in caps.conf can be
copied to $initramfs/etc/cmdline with "-i caps.conf /etc/cmdline".
Also all modules have to be loaded in the initramfs via "--add-drivers".
The resulting initramfs creation would look like this:
--add-drivers "autofs4 sunrpc ipt_REJECT nf_conntrack_ipv4 \
nf_defrag_ipv4 iptable_filter ip_tables
ip6t_REJECT nf_conntrack_ipv6 nf_defrag_ipv6 xt_state nf_conntrack
ip6table_filter ip6_tables dm_mirror dm_region_hash dm_log uinput ppdev
parport_pc parport ipv6 sg 8139too 8139cp mii i2c_piix4 i2c_core ext3
jbd mbcache sd_mod crc_t10dif sr_mod cdrom ata_generic pata_acpi ata_piix
dm_mod" \
