Subject: [PATCH] afsio: process windows file paths consistently

Windows file paths can use either '\' or '/' as a path
separator.  libafscp on the other hand requires '/' and argv[0]
will always use '\'.

Introduce a new function ConvertAFSPath() which converts the
input path to '/' and converts \\afs to /afs.  A future commit
should access the registry and make use of the NetbiosName and
MountRoot values to perform the conversion correctly.
