f2fs: bug fixes for 3.8-rc2 

This patch-set includes two major bug fixes:
 - incorrect IUsed provided by *df -i*, and
 - lookup failure of parent inodes in corner cases.
 
 [Other Bug Fixes]
 - Fix error handling routines
 - Trigger recovery process correctly
 - Resolve build failures due to missing header files
 
 [Etc]
 - Add a MAINTAINERS entry for f2fs
 - Fix and clean up variables, functions, and equations
 - Avoid warnings during compilation
