40d9f8a709 msdosfs_read(): avoid integer overflow for files > 2GB, when
difference between current read position and file size
	is bigger than 2GB

This fixes problem first noted in FreeBSD PR#15639 and sent
by Martin J. Laubach in kern/9046, though the implementation
differs a bit.

07fd899a7f Add new CLUST_END and use it as parameter to pcbmap() when searching
for end cluster, instead of explicitly passing 0xffff. This fixes potential
problem for FAT32, where cluster number may be legally bigger than 0xffff.

Also change clusteralloc() so that fillwith is not explicitly passed by caller
anymore (there is no need to use anything other than CLUST_EOFE).

e2698cd72a Fix definition of MSDOSFSEOF(), which got broken in rev. 1.13.
It's shape is a bit different now than it was in rev 1.12, but is functionally
equivalent. Also add a comment explaining it's sense.

This fixes breakage reported after LP64 fixes in kern/8037, and
also kern/9116 and kern/9206.

89015c4648 Add new VFS op routine - vfs_done and call it on filesystem detach
in vfs_detach(). vfs_done may free global filesystem's resources,
typically those allocated in respective filesystem's init function.
Needed so those filesystems which went in via LKM have a chance to
clean after themselves before unloading. This fixes random panics
when LKM for filesystem using pools was loaded and unloaded several
times.

For each leaf filesystem, add appropriate vfs_done routine.

f759642ae2 Fix a problem in previous: we can't blindly assume that we have
wincnt entries available at the offset the file has been found. If the dos
directory entry is not preceded by appropriate number of long name
entries (happens e.g. when the filesystem is corrupted, or when
the filename complies to DOS rules and doesn't use any long name entry),
we would overwrite random directory entries.

There are still some problems, the whole thing has to be revisited and solved
right.

ead528ba12 msdosfs_lookup(): initialize denode's de_fndcnt properly even for
"found" case. This information is important for msdosfs_rename(),
when the target filename is "long" and the file exists -
it gets unlinked and the entries are re-used, but if de_fndcnt was
left zero, createde() thinks there are no entries to store the
long filename of moved file and long filename is "lost".

e682a080e9 In spec_close(), if we're not doing a non-blocking close and VXLOCK is
not set, unlock the vnode before calling the device's close routine and
relock it after it returns. tty close routines will sleep waiting for
buffers to drain, which won't happen often times as the other side needs
to grab the vnode lock first.

Make all unmount routines lock the device vnode before calling VOP_CLOSE().
