Subject: [PATCH REC 0/3] ext4:Factor common code from convert and split unwritten.

These patches factor common code from ext4_ext_convert_to_initialized() and
ext4_split_unwritten_extents(), so that extent-move-on-write in snapshot and
punch-hole can be built on the common code as well.

ext4:Add a function merging extent right and left.
ext4:Add two functions splitting an extent.
ext4:Reimplement convert and split_unwritten.
