This commit adds the functionality which had previously only been in
the tst_extents command to debugfs. The debugfs command extent_open
will open extent tree of a particular inode, and enables a series of
commands which will allow the user to interact with the extent tree
directly. Once the extent tree is closed via extent_open(), these
additional commands will be disabled again.
This commit exports two new functions from lib/ext2fs/extent.c which
had previously been statically defined: ext2fs_extent_node_split() and
ext2fs_extent_goto2().

Create a version of debugfs which only supports read-only examination
of the file system metadata (but not the data blocks). The idea is
that this version of debugfs might be suitable to be setuid root, and
executable only by members of a particular group, or setgid disk, and
globally executable, depending on the security/privacy policies in
force at a particular site.
