Linux 2.6.35 compat: filp_fsync() dropped 'stuct dentry *'

Browse Source 
The prototype for filp_fsync() drop the unused argument 'stuct dentry *'.
I've fixed this by adding the needed autoconf check and moving all of
those filp related functions to file_compat.h.  This will simplify
handling any further API changes in the future.
