Released Pigeonhole v0.5.2.rc1 for Dovecot v2.3.2.rc1.

[Stephan Bosch]

Hello Dovecot users,

Here is the Pigeonhole release candidate that goes with the Dovecot
v2.3.2 release candidate. Much like version 0.4.24 for Dovecot v2.2, 
this release consists mostly of fixes that accumulated over the last few 
months. Beyond that, this release contains the new IMAP FILTER=SIEVE 
capability, which was also released earlier with 2.2.24 (with a few 
additional fixes).

Changelog v0.5.2:

+ Implement plugin for the a vendor-defined IMAP capability called
   "FILTER=SIEVE". It adds the ability to manually invoke Sieve filtering
   in IMAP. More information can be found in
   doc/plugins/imap_filter_sieve.txt.
- The Sieve address test caused an assertion panic for invalid addresses
   with UTF-8 codepoints in the localpart. Fixed by properly detecting
   invalid addresses with UTF-8 codepoints in the localpart and skipping
   these like other invalid addresses while iterating addresses for the
   address test.
- Make the length of the subject header for the vacation response
   configurable and enforce the limit in UTF-8 codepoints rather than
   bytes. The subject header for a vacation response was statically
   truncated to 256 bytes, which is too limited for multi-byte UTF-8
   characters.
- Sieve editheader extension: Fix assertion panic occurring when it is
   used to manipulate a message header with a very large header field.
- Properly abort execution of the sieve_discard script upon error.
   Before, the LDA Sieve plugin attempted to execute the sieve_discard
   script when an error occurs. This can lead to the message being lost.
- Fix the interaction between quota and the sieve_discard script. When
   quota was used together with a sieve_discard script, the message
   delivery did not bounce when the quota was exceeded.
