puffs - status report 5

[Tatsiana Severyna]

This week I've merged puffs and libpuffs changes from NetBSD,
performed some minor cleanup in sources (mostly libpuffs) and finally
fixed bug witch didn't allow to reuse message park for several
messages. This bug also seems to exist in NetBSD, but doesn't show up
there because of enabled page caching. Next week I'm going to port
psshfs. I've already commited vanilla sources to perforce.
