dhcpcd-4.0.0-alpha2 ready for review

[Roy Marples <roy%marples.name@localhost>]

And hopefully the last!
http://roy.marples.name/dhcpcd/dhcpcd-4.0.0-alpha2.tar.bz2

Changes from alpha1
dhcpcd.sh is now looking slick and minimal.
ntp, nis and hostname lookup have been moved into example hook scripts.
dhcpcd.conf is now installed by default to request everything dhcpcd.sh needs, 
and ntp-servers also.
classless_static_routes="1.2.3.4/8 5.6.7.8/16" is now exported to the script.
dhcpcd.sh and dhcpcd.conf now have man pages.

The last thing todo is decide on the following
Do we want per interface conigs in dhcpcd.conf? If so provide an example.
We currently trim leading and trailing whitespace in dhcpcd.conf. Should we 
provide a complex mechanism to allow spaces at the start/end of values?
If the hostname is an FQDN (foo.bar.com) should we transmit it as such by 
default?

Thanks
