[PATCH 0/5 v6] e2fsprogs: Support for orphan file feature

  Hello,

  This is the fifth version of support for orphan file feature in e2fsprogs.
I've rebased it on top of maint branch as Ted already merged initial fixes.
I've also fixed up some issues Ted has already found.  I'm not aware of any
outstanding issue with the series, xfstests pass fine with it.

Changes since v5:
* Fix e2fsck handling of orphan file when metadata checksums are disabled

Changes since v4:
* Make sure we consistently speak about orphan_file and orphan_present feature,
  not flag, in error messages.
* Do not make orphan_file feature default yet
* Make sure mke2fs does not complain if orphan_file feature got enabled by the
  profile but user decided to disable journal.
* Fixed up value of ORPHAN_PRESENT feature
* Fixed several introduced -Wall warnings
* Fixed e2fsck errorcodes
* Rebased on top of current maint branch (some patches already merged)

Changes since v3:
* updated to compute checksum also from physical block

Changes since v2:
* rebased onto current master branch
* fixed various bugs I've spotted during testing
* added support for debugfs, dumpe2fs, e2image
* changed code to use dynamically allocated inode number instead of fixed one
