Update to the 20141022 snapshot of GCC 4.9.2.

Also remove those traces of @dirrm that were are added dynamically
via the Makefile.
Add missing dependencies.

* USES=pkgconfig was missing so exiv2 detection was broken, for example.
* USE_QT5=declarative and USE_QT5=printsupport were missing, and the latter
  is required for the port to build correctly with the upcoming Qt 5.3.2.
  I've added an upstream commit to properly detect and use PrintSupport in
  the build process as well.

Add archivers/liblz4. There is already archivers/lz4, which it looks
like might be an old version of this, but it only installs a binary.
This installs binaries and libraries/headers.

LZ4 is a very fast lossless compression algorithm, providing compression speed
at 400 MB/s per core, scalable with multi-cores CPU. It also features an
extremely fast decoder, with speed in multiple GB/s per core, typically
reaching RAM speed limits on multi-core systems.

A high compression derivative, called LZ4_HC, is also provided. It trades CPU
time for compression ratio.

The libraries are BSD licensed, and the binaries are GPLv2.

Update dovecot2 to 2.2.15, and add an LZ4 option that uses liblz4.

ChangeLog:

Some small fixes and changes to v2.2.14. This release is mainly in the hope
that it could still make it into the next Debian stable instead of v2.2.14 -
mainly because of a couple of new assert crashes that started happening in
v2.2.14 and should be fixed now.

	* Plugins can now print a banner comment in doveconf output
	  (typically the plugin version)
	* Replication plugin now triggers low (instead of high) priority for
	  mail copying operations.
	* IMAP/POP3/ManageSieve proxy: If destination server can't be
	  connected to, retry connecting once per second up to the value of
	  proxy_timeout. This allows quick restarts/upgrades on the backend
	  server without returning login failures.
	* Internal passdb lookups (e.g. done by lmtp/doveadm proxy) wasn't
	  returning failure in some situations where it should have (e.g.
	  allow_nets mismatch)
	* LMTP uses mail_log_prefix now for logging mail deliveries instead of
	  a hardcoded prefix. The non-delivery log prefix is still hardcoded
	  though.

	+ passdb allow_nets=local matches lookups that don't contain an IP
	  address (internally done by Dovecot services)
	+ Various debug logging and error logging improvements
	- Various race condition fixes to LAYOUT=index
	- v2.2.14 virtual plugin crashed in some situations
Update mail/spamass-milter to 0.4.0.

Brief summary of changes (taken from upstream release announcement):

- -C option to change the default reject code
- -S option to specify a path to sendmail (for the -x option)
- -R option to specify the rejection message
- -a option to skip messages that were authenticated
- IPv6 address support
- zombie process fix for the - option introduced in 0.3.2

Some of these changes (notably the -R and -a flags and the IPv6
support) were previously included in the port via patch files, which
are now unneeded and have been removed.
