manu | Work around deadlock between fstchg and fstcnt
When suspending a filesystem in fstrans_setstate(), we wait on
fstcnt for threads to finish transactions. While we do this, any
thread trying to start a filesystem transaction will wait on fstchg
in fstrans_start(), a situation which can deadlock.
The wait for fstcnt in fstrans_setstate() can be interrupted by
a signal, but the wait for fstchg in fstrans_start() cannot. Once
most processes are stuck in fstchg, it is impossible to send a
signal to the thread that waits on fstcnt, because no process
respond anymore to user input.
We fix that by adding a timeout to the wait on fstcnt in
fstrans_setstate(). This means suspending a filesystem may fail,
but it was already the case when the sleep was interupted by
a signal, hence calling function must already handle a possible
failure.

Bring back three state file system suspension:
NORMAL -> SUSPENDING -> SUSPENDED
and add operation fstrans_start_lazy() that only blocks while SUSPENDED.
Change vndthread() support operation handle_with_rdwr() to bracket
its file system operations by fstrans_start_lazy() and fstrans_done().

Vnode state, lock and fstrans cleanup:
- Rename vnode state "VS_ACTIVE" to "VS_LOADED" and add synthetic
state "VS_ACTIVE" to assert a loaded vnode with usecount > 0.
- Redo FSTRANS in vnode_if.c and use it for VOP_LOCK and VOP_UNLOCK.
- Cleanup the genfs lock operations.
- Make "struct vnode_impl" member "vi_lock" a krwlock_t again.
- Remove the lock type argument from fstrans_start and
fstrans_start_nowait,
remove now unused FSTRANS state "FSTRANS_SUSPENDING".
