xfs: make some xfs project quota tests generic

Browse Source 
This patch makes some xfs project quota tests generic,
so that there is at least some coverage on ext4 for this
(semi-)new feature.

It requires bleeding edge xfsprogs, so that xfs_quota and
xfs_io's chproj command can operate on "foreign" filesystems,
and requires relatively new e2fsprogs to enable the project
quota feature on-disk.

The mechanism for enabling project quota on ext4 is a bit
arcane, but hopefully I've encapsulated it reasonably well here.

Changes:

* look for "project" feature in _require_prjquota
* look for accounting not enforcement (-P) in _require_prjquota
* add a _scratch_enable_pquota to turn on project quota feature
* s/pquota/quota/ in _qmount_option for ext4
* add helper to test for xfs_io chproj on foreign filesystems
* switch from block to inode quota in xfs/133 because empty
  ext4 dirs consume one block
* cosmetic/generic changes for mkfs, require tests, etc.
