Released Pigeonhole v0.4.22 for Dovecot v2.2.34.

[Stephan Bosch]

Hello Dovecot users,

Here is a new Pigeonhole release that goes with the new Dovecot v2.2.34
release. This release is not strictly necessary, as previous versions
should be usable as well. This release only contains bugfixes.

Changelog v0.4.22:

- Fixed filesystem path handling problem: sieve plugin could have
  assert-crashed with specific path lengths with: "Panic: file
  realpath.c: line 86 (path_normalize): assertion failed: (npath_pos +
  1 < npath + asize)".
- Sieve extprograms plugin: Large output from "execute" command crashed
  delivery. Fixed buffering issue in code that handles output from the
  external program.
- editheader extension: Extensively reworked the low-level
  implementation of adding and removing headers. This solves a few
  integer arithmetic problems reported by Clang runtime checks, but also
  improves code structure and reliability in general.
- imapsieve: Fix assert crash occurring when selected messages are
  expunged concurrently by the time Sieve filter is to be applied.
- imap4flags extension: Fix binary byte-code corruption occurring when
  the setflag, addflag, or removeflag command's flag-list is a variable.
- enotify extension: mailto method: Fixed parsing of mailto URI with
  only a header part.
- enotify extension: mailto method: Make sure "From:" header is set to a
  usable address and not "(null)".
- Fixed writing address headers to outgoing messages. It sometimes
  erroneously applied another layer of MIME header encoding.
