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.

8c9e62b299 Revert to using flushtlb instead of invlpg 
Somehow the usage of invlpg causes Minix to crash on Qemu. Reverting
temporarily until we have a proper fix.

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).

4857d5d554 add -lminixfs with fs support routines

	  so mfs and ext2 can share it
	. add vfs credentials retrieving function, with
	  backwards compatability from previous struct
	  format, to be used by both ext2 and mfs
	. fix for ext2 - STATICINIT was fed no.

78183bddff Let FSes exit themselves upon system shutdown 
During shutdown all processes are semi-exited and FSes are unmounted.
This semi-exit causes trouble for FUSE mounts as they still need access
to file descriptors and working directory in order to unmount.
