sys: FspFsvolReadNonCached: trim ReadLength 
During CreateProcess/CreateSection Windows locks the image file (using AcquireFileForNtCreateSection),
gets the image file size and then reads the image file. Unfortunately if the file system (erroneously) reads
past the file size, Windows can bugcheck. This allows a faulty or malicious file system to crash Windows.

This commit adds a check in WinFsp to mitigate this problem.

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.
