[flashboot] Flashboot for OpenBSD 5.0

[Johan Ryberg]

Hi

I have committed several changes to kernel configurations for Soekris,
WRAP12, PCEngines and COMMELL-LE564 to make Flashboot work on OpenBSD
5.0. We are also not using svnd any more since it has been integrated
to vnd

Since I only have Soekris 4801 and there need to be more testing on
other platforms to verify that it work as expected. Please test and
report back to the list.

I will put binaries on github (https://github.com/openbsd/flashboot)
to night and the downloads will be available from the wiki page.

Best regards Johan
