sys: FSP_FSCTL_QUERY_WINFSP 
The FSP_FSCTL_QUERY_WINFSP code provides a simple method to determine if
the file system backing a file is a WinFsp file system. To use issue a

    DeviceIoControl(Handle, FSP_FSCTL_QUERY_WINFSP, 0, 0, 0, 0, &Bytes, 0)

If the return value is TRUE this is a WinFsp file system.

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.
