823e42c3e3 Make AVFS deal intelligently with back calling FSes
PUFFS file systems need to make back calls for every operation we
send to them. Consequently, they cannot handle block reads and writes
themselves. Instead, the root file system has to do it (for now).

When the mount operation causes an FS to make a back call, AVFS now
concludes that every block read and write for that FS has to go
through the root file system.

203937456e Fix off-by-one errors and increase PATH_MAX to 1024
In some places it was assumed that PATH_MAX does not include a
terminating null character.

Increases PATH_MAX to 1024 to get in sync with NetBSD. Required some
rewriting in AVFS to keep memory usage low (the stack in use by a thread
is very small).
