Released Pigeonhole v0.4.7.rc1 for Dovecot v2.2.16.rc1

[Stephan Bosch]

Hello Dovecot users,

Last time I had a few stupid problems in the releases, so I'll follow
Timo's example and I release an RC first.

The highlights include the implementation of the index and metadata
extensions. Quite a few bugs are fixed as well.

Changelog v0.4.7:

* editheader extension: Made protection against addition and deletion of
  headers configurable separately. Also, the `Received' and
  `Auto-Submitted' headers are no longer protected against addition by
  default.
* Turned message envelope address parse errors into warnings.
* The interpreter now accepts non-standard domain names, e.g.
  containing '_'.
+ Implemented the Sieve index extension (RFC 5260).
+ Implemented support for the mboxmetadata and servermetadata extensions
  (RFC 5490).
+ Implemented new sieve commands for the doveadm command line utility.
  These commands are currently limited to ManageSieve operations, but
  the other current sieve tools will be migrated to doveadm in the near
  future as well.
+ Added more debug output to binary up-to-date checking.
- The Sieve interpreter now flushes duplicate database during start
  phase of result execution rather than commit phase. This makes sure
  locks on the duplicate database are released as soon as possible,
  preventing contention.
- Performed a few optimizations in the lexical scanner of the language.
- Fixed bug in `:matches' match-type that made a pattern without
  wildcards match as if there were a '*' at the beginning.
- file storage: Restructured storage initialization to address backwards
  compatibility issues.
- Fixed crash in validation of the string parameter of the comparator
  tag.
- extprograms extension: Made sure supplemental group privileges are
  also dropped. This was a problem reported by Debian lintian.
- Fixed bug in handling of binary errors for action side-effects and
  message overrides.
