Released Pigeonhole v0.5.1 for Dovecot v2.3.1.

[Stephan Bosch]

Hello Dovecot users,

Here's the Pigeonhole release that goes with Dovecot v2.3.1. You will
need this release for Dovecot v2.3.1, because the previous v0.5.0.1
release will not work. Apart from compatibility changes, it only
contains bugfixes.

Changelog v0.5.1:

- Explicitly disallow UTF-8 in localpart in addresses parsed from Sieve
  script.
- editheader extension: Corrected the stream position calculations
  performed while making the modified message available as a stream.
  Pigeonhole Sieve crashed in LMTP with an assertion panic when the
  Sieve editheader extension was used before the message was redirected.
  Experiments indicate that the problem occurred only with LMTP and that
  LDA is not affected.
- fileinto extension: Fix assert panic occurring when fileinto is used
  without being listed in the require line, while the copy extension is
  listed there. This is a very old bug.
- imapsieve plugin: Do not assert crash or log an error for messages
  that disappear concurrently while applying Sieve scripts. This event
  is now logged as a debug message.
- Sieve extprograms plugin: Large output from "execute" command crashed
  delivery. Fixed buffering issue in code that handles output from the
  external program.

The release is available as follows:
