mdev: fix counting of '%' in pattern

mdev: fix whitespace damage

- optionally pass additional flags down to nm

- not sure but i may have had the shutdown-time wrong and no records to verify

- untangle the implementation of the small and huge last applets

mdev: suppress "may be used uninitialized" warning

mdev: add support for "only rename" option in mdev.conf

dnsd: fixes various segfaults.
One was a lib api change that was not updated and another
is a stack buffer overflow.
It also adds support for '*' in dnsd.conf. It resolves all hostnames to
a specific ip address. This is useful if you for example want redirect
all http traffic to your first-boot-web-wizard on you router/firewall.

By Timo Teras

modprobe: fix for blacklisting

The patch makes the order of the alias/blacklist in modprobe.conf
irrelevant (like module-utils' modprobe). In first patch the alias had
to be defined before the blacklist which caused problems because the
modprobe.conf file is read before /lib/modules/*/modules.alias.

The attatched patch will mark the blacklisted module itself rather than
trying to find the alias that points to the blacklisted module and test
this flag later in the alias resolving stage.

last: make its output more like "standard" last (aka "fancy last").
The main difference is that LOGIN lines are still shown by non-fancy one.
