[patch] loader.c parse dogtail=url parameter

[Alexander Todorov <atodorov@xxxxxxxxxx>]

Hello,
This patch allows /sbin/loader to parse dogtail=url boot cmd line 
parameter and pass it as parameter to /usr/bin/anaconda in stage2.img.

How can I test the new loader?
I have modified the original images/boot.img and replaced the loader 
found in initrd.img. I am able to boot from CDROM with the modified 
image but a little after the beginning it fails with:
Kernel panic - not syncing: VFS: Unable to mount root fs on 
unknown-block(9,1)

According to this site:
http://www.informit.com/articles/article.asp?p=169466&seqNum=2&rl=1
the boot.iso image can be burned to CDROM and used to perform network 
installs.

Any help is appreciated.

Greetings,
Alexander.
