initialize i_flag not i_flags

iflush becomes vflush and moves to vfs_subr.c

lint

device uniqueness and aliasing is now handled at the vnode level;
bdevvp moves to vfs_subr.c, igrab is replaced by vget

merge inode and nfsnode tables into a single vnode table;
link together all vnodes associated with a particular mount point

minor cleanups

try to flush all inodes when unmounting;
add debugging info to find out what is busy

generalize the buffer pool so that NFS can become a client

purge vnode type when unneeded and returned to the free list so that
getnewino does not try to delete it from block device list more than once.

detect release of free inodes (from stale file handles)
and just put them on the free list

update reference counts on vnodes using VREF

compatibility code to assign a generation number to inodes that have none

put in explicit lock and unlock so that locking can be checked

merge in vnodes

geteblk => malloc for copy of indirect pointers

geteblk => malloc, so m_bufp => m_fs as it should be

change free() to blkfree() to allow for malloc()/free()

working with pack labels

add ifdefs for dev_bsize (almost working)
