[Dovecot] Multiple quota roots with quota-fs backend

[Ralf Becker]

Ok... here it is :-)

BTW:
The patch also includes another AIX specific code enhancement:

On AIX the quota block size DEV_BSIZE should be 1024. This is easy to 
detect, because there is a macro DQBSIZE defined in jfs/quota.h. I've 
changed quota-fs.c to use DQBSIZE (if present) to initialize DEV_BSIZE.
