Subject: Updated ext4 quota design document

I've created an updated quota design document here:

https://ext4.wiki.kernel.org/index.php/Design_For_1st_Class_Quota_in_Ext4

No major changes from last time.

One new thing is a proposed (optional) change to the quota format,
to use the 32-bit dqpb_pad field in the v2r1 on-disk quota structure as
a 32-bit CRC of the quota entry.  This would allow the quota system to
detect corrupted quota entries.  Jan, what do you think?
