Released Pigeonhole v0.4.7.rc2 for Dovecot v2.2.16

[Stephan Bosch]

Hello Dovecot users,

The rc1 release showed a few problems with the up-to-date checking of
on-disk binary files. The binary files contain some metadata about the
script these were compiled from. If this doesn't match the current
script anymore, the script is recompiled. One of these metadata items is
the script location. However, this location wasn't normalized, so when
the binary would be compiled with sievec it depended on the path
provided at the command line.

When dumping a script binary, the metadata is now printed as well. Also,
I added more debug log lines about up-to-date checking.

I improved backwards compatibility for the file script storage a bit
relative to the last version. It now properly recognizes a regular file
at the symlink path, even when the storage path itself doesn't exist.

Changelog v0.4.7 (updated):

* 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 about binary up-to-date checking.
+ Added script metadata to binary dump output.
- Fixed Sieve script binary up-to-date checking by normalizing the
  script location.
- The Sieve interpreter now flushes the 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.
- 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.
- file script storage: Restructured storage initialization to address
  backwards compatibility issues.
- dict script storage: Fixed small memory allocation bug.
