jdolecek 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.

jdolecek 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".

enami fee96e1746 Check if the type of device node isn't VBAD before touching v_specinfo. If
the device vnode is revoked, the field is NULL and touching it causes null
pointer derefercence.

wrstuden 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().

cgd 651b44e211 Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
