Remove useless and harmful sync(2) call in umount(8)
Remove sync(2) call before unmount(2) in umount(8). This sync(2) is useless
since unmount(2) will perform a VFS_SYNC anyway.
But moreover, this sync(2) may be harmful, as there are some situation where
it cannot return (unreachable NFS server, for instance), causing umount -f
to be uneffective.
Fix soft NFS force unmount
For many reasons, forcibly unmounting a soft NFS mount could hang forever.
Here are the fixes:
- Introduce decents timeouts in operation that awaited NFS server reply.
- On timeout, fails operations on soft mounts with EIO.
- Introduce NFSMNT_DISMNTFORCE to let the filesystem know that a
  force unmount is ongoing. This causes timeouts to be reduced and
  prevents the NFS client to attempt reconnecting to the NFS server.
Also fix a race condition where some asynchronous I/O could reference
destroyed mount structures. We fix this by awaiting asynchronous I/O
to drain before proceeding.

split PRU_SEND function out of pr_generic() usrreq switches and put into
separate functions

   xxx_send(struct socket *, struct mbuf *, struct mbuf *,
       struct mbuf *, struct lwp *)

  - always KASSERT(solocked(so)) even if not implemented

  - replace calls to pr_generic() with req = PRU_SEND with calls to
    pr_send()

rename existing functions that operate on PCB for consistency (and to
free up their names for xxx_send() PRUs

  - l2cap_send() -> l2cap_send_pcb()
  - sco_send() -> sco_send_pcb()
  - rfcomm_send() -> rfcomm_send_pcb()
