This patchset adds inline extent format support to f2fs userspace tools,
complementing the kernel-side inline extent feature.
The inline extent format stores block address mappings as compact extent
entries directly in the inode's data block address area (i_addr[]),
identified by dual magic numbers. This provides O(log n) lookup via
binary search and reduces space consumption for files with contiguous
block allocations.
Patch 1: fsck/dump core support -- inline extent operations (lookup,
insert, merge, split, truncate, format conversion),
integration with datablock_addr(), set_data_blkaddr(), and
fsck sanity checks.
Patch 2: Build system -- add --disable-inline-extent configure option,
wire iextent.c/iextent.h into fsck build, define
HAVE_INLINE_EXTENT macro.
Patch 3: f2fs_io tool -- add "extent" flag support for setflags/
clearflags/getflags commands.

f2fs_io: add support to clear/set extent flags
