dll,sys: fix issue #369 
The original WinFsp protocol for shutting down a file system was to issue
an FSP_FSCTL_STOP control code to the fsctl device. This would set the IOQ
to the "stopped" state and would also cancel all active IRP's. Cancelation
of IRP's would sometimes free buffers that may have still been in use by
the user mode file system threads; hence access violation.

To fix this problem a new control code FSP_FSCTL_STOP0 is introduced. The
new file system shutdown protocol is backwards compatible with the original
one and works as follows:

- First the file system process issues an FSP_FSCTL_STOP0 control code which
sets the IOQ to the "stopped" state but does NOT cancel IRP's.

- Then the file system process waits for its dispatcher threads to complete
(see FspFileSystemStopDispatcher).

- Finally the file system process issues an FSP_FSCTL_STOP control code
which stops the (already stopped) IOQ and cancels all IRP's.

sys: fsmup device 
- This commit introduces the fsmup device, which is a major change in how
network file systems are handled. Previously every network file system's
fsvol device was directly registered with the MUP. Now there is a single
fsmup device that is registered with the MUP; network file systems' fsvol
devices register with fsmup instead. The fsmup device maintains a prefix
table which it uses to demultiplex and forward requests to the appropriate
fsvol device.
- This device change was necessatitated to fix issue #87.
