php53: fix on darwin

* add libssh2 to build inputs (configure fails without this)
* link with stdc++
* add icu/lib directory to DYLD_LIBRARY_PATH (and wrap binaries with this
  environment variable
* add libiconv to build inputs
* fix --with-iconv configure flag (was --with-iconv-dir which is not a valid
  flag)
php53: add optional pcntl flag
php53: restore nix gd version
php53-xdebug: add expression
Update mumble to 1.2.4

Now it should have opus. The source code of opus comes with mumble.
Updating umurmur to 0.2.13

Now opus works.
synergy: Update to new upstream version 1.4.12.

This brings in support for encryption and thus requires the crypto++ library as
an additional dependency. Unfortunately the upstream integration isn't quite the
way we'd like it to be, so we need to add a small patch to ignore the bundled
version and use the package from nixpkgs.

synergy: Add support for XrandR.

Nowadays, multiple monitor setups are quite common, so I suppose we'd want
support for that. Especially because users might get confused if synergy is
unable to pick the right screen resolution and thus cause edges to be cut off
from the available pointing area.

The postPatch hook is to force cmake into thinking that we have XRRNotifyEvent,
which we _do_ have with the xrandr version shipped in nixpkgs. Automatic
detection from CMakeLists.txt fails here because it tries to search for the
symbol within the libX11 store path.

synergy: Add support for Xinput2.

This is needed in order to support devices such as gamepads or tablets.

synergy: Enable unit tests.

Integration tests don't seem to work right now, so let's see if we can figure
out a way to enable them later. But at least running unit tests is better than
not running any tests :-)

php53: Don't use bundled version of libgd.

This fixes a copy & paste error I made in 486e918, which resulted in PHP being
built with the bundled version of GD instead of the one we have in nixpkgs.

Thanks to @peti for noticing.

chromium: Mark beta and dev versions lowPrio.

I'm still wondering why noone has reported this, but I found out about this
while trying to introduce someone to NixOS, eventually wondering why it is going
to install version 29 when using "nix-env -i chromium".

So, in hope that everyone out there using the package is using the attribute,
let's make _stable_ the default here.

ninja: Update to v1.3.4 and drop unzip dependency.

Version 1.2.0 is way too old in order to build the latest chromium (29) version,
so let's get it up to date (especially because no other package is referencing
ninja, so it should be non-critical).

The dependency on unzip is not needed here, because GitHub also provides
archives in tar.gz format.

chromium: Update all channels to latest versions.

Chromium 28.0.1500.52 finally is stable, so the release channels are now:

stable: 28.0.1500.52 (builds fine, tested)
beta:   28.0.1500.52 (same as stable)
dev:    29.0.1541.2  (patch rebased, builds fine, tested)

The user namespace patch doesn't apply for version 29, so I had to rebase it
against the current trunk (revision 207742).

And as version 27 is outdated, we no longer need to distinguish versions for
patching the hardcoded gcc path in core/core.gypi.

iksemel: Add new package with version 1.4.

This library is used by Zabbix in order to send XMPP alerts/notifications.

Signed-off-by: aszlig <aszlig@redmoonstudios.org>
zabbix2: Add optional XMPP support using iksemel.

This uses recurseForDerivations directly after using callPackage magic to ensure
that the input attributes can be overriden *and* nix-env shows the package as in
recurseIntoAttrs.

The reason for making this optional is because there probably is only a minority
of people who want to use XMPP and we don't want to introduce an additional
dependency for the majority, do we?

synergy: Take over maintenance.

I'm heavily using synergy for daily work, so I'm most probably going to watch
out for changes/improvements/bugs :-)

synergy: Use bundled crypto++ on non-Linux archs.

Seems that crypto++ in nixpkgs doesn't build on Darwin, so let's use bundled
crypto++ until the version in nixpkgs works well.

This refers to the following build:

http://hydra.nixos.org/build/5404516

Hopefully, this will fix it on Mac OS X, because I don't have a Darwin machine
for testing.

synergy: Only pass cryptopp on Linux platforms.

The second failure, and the last one I'm going to try today:

http://hydra.nixos.org/build/5404634

On the bright side there is at least the fact that version 1.4.10 has failed on
Darwin already, so I guess we don't have a lot of Mac users using Synergy.

Latest (failed) build of 1.4.10:
