Zachary Turner 5e117855c3 [msf] Resubmit "Rename Msf -> MSF".
Previously this change was submitted from a Windows machine, so
changes made to the case of filenames and directory names did
not survive the commit, and as a result the CMake source file
names and the on-disk file names did not match on case-sensitive
file systems.

I'm resubmitting this patch from a Linux system, which hopefully
allows the case changes to make it through unfettered.
