ext4: add data structures for the extent status tree
This patch adds two structures that supports extent status tree, extent_status
and ext4_es_tree. Currently extent_status is used to track a delay extent for
an inode, which record the start block and the length of the delay extent.
ext4_es_tree is used to store all extent_status for an inode in memory.
