Add project quota changes to all the places where group quota field
is used:
* add separate project quota members into various structures
* split project quota and group quotas so that instead of overriding
the group quota members incore, the new project quota members are
used instead.
* get rid of usage of the OQUOTA flag incore, in favor of separate group
and project quota flags.
* add a project dquot argument to various functions.
No externally visible interfaces changed and no superblock changes yet.
