[Dovecot] quota-rewrite patch & userdb quota overriding

[Juan C. Blanco]

Hello Alan, I think that the last quota-rewrite patchs in the dovecot 
site is not the correct one since Timo updated the source/hg tree but I 
think that the patch was not updated at the time.

I have a modified patch that works for me, if you want to test it I can 
send it to you off list.

Regards
Juan C. Blanco
