v1->v2:
 - Remove the document about journal_cycle_record mount option.

Hello!

This is the e2fsprogs part of the ext4 journal cycled record
transactions option feature(corresponding kernel part is at [1]). It
add a new parameter to record the journal head of a clean filesystem,
mke2fs initialize it to the start of journal area, and e2fsck check and
fix it if it's bad, and also update it after recovering journal. Passed
functional tests.

Thanks,
Yi.
