Renamed lfs_fs_findfreeblocks -> lfs_fs_gc, tweaked documentation

Browse Source 
The idea is in the future this function may be extended to support other
block janitorial work. In such a case calling this lfs_fs_gc provides a
more general name that can include other operations.

This is currently just wishful thinking, however.
