[Dovecot] first crack at auto-trash plugin

[David Powers]

I have written an alpha version of an auto trash plugin for dovecot. 
When compiled in any mail expunged from a non-Trash folder is moved to a 
folder named Trash.  As of yet the folder is not created if it doesn't 
exist (the process fails before expunge).  I would appreciate feedback 
of any sort.  In addition, I am currently getting an error I haven't 
been able to puzzle out in the logs when it runs:

Mar 21 15:22:01 david dovecot: imap(david at grayskies.net): Timeout leak: 
0x807fad0

I see that it seems to relate to transactions somehow, but my few hours 
of playing with dovecot haven't given me the answer - so ideas/patches 
to the code would also be nice.
