Import an other round of changes from marcuscom cvs and bump PORTREVISION:
- Bump build_name from 72 characters to 255 characters.
- Sync latest port fail reasons and patterns with pointyhat.
- Switch to cvsup17 as default csup server
- Fix a problem where port directories where not canonicalized, and could end
up looking like dir/../otherdir.
- Save some screen space by reducing space between top menu and content in
queue view in webui.
Note that if upgrading you have to apply the canges to your database by hand.
