use several system libraries instead of bundled

see http://www.linuxfromscratch.org/blfs/view/cvs/xsoft/chromium.html

1. Needs to call makeTest or else nothing happens when you run
   `nix-build nixos/tests/postgresql.nix`.

2. Tests run as root, so there needs to be a corresponding user in
   PostgreSQL.

I suspect these functions aren't widely used, but they are enabled in
PostgreSQL on Ubuntu and Arch.

- Changed sha256 of src file, as this was apparantly changed on the
website

- Added missing libs: some X libs, alsa, dbus

- Changed patch to $out/houdini/Licensing.opt
localValidatorDir = ... was commented out in original file
so sed had no effect

- add export QT_XKB_CONFIG_ROOT
Without it only modifier keys worked, no text input

Rsync has its own patched compress function, and to be able to use the `-z` flag, it needs to use that one.

With `-zz` rsync can use an external zlib, but then it can't talk to older rsync versions.

cc NixOS#27503

See http://lists.gnu.org/archive/html/info-gnu/2017-07/msg00007.html
for release announcement

* network-manager-l2tp: don't run ./configure twice

* network-manager-l2tp: remove automake/autoconf

The previous package didn't build properly due to a bug in the build
script, and the nixos module didn't evaluate due to missing descriptions
in the options. This fixes both issues.

It also adds missing command-line options that weren't able to be set
and properly converts bools to the strings exhibitor expects.

Suggest prefixing commit messages that touches NixOS code with
"nixos/<module>" instead of the current "<name> service" prefix.

"<name> service" is limiting in that NixOS code is more than the
services. It is also easier to spot NixOS changes with explicit
"nixos/..." prefix.

I've tested the resulting build against the sample
"2013_04_04_GNSS_SIGNAL_at_CTTC_SPAIN" dataset linked from:

Many thanks to @knedlsepp for suggestions in NixOS#27505 that have
substantially improved this package!

Add option for archive support and fix dvdread and dvdnav support.

clarify note about stable and testing versions

Also really use QT5 and switch download location to GitHub.

Or else nix-env updates the stable version to unstable.

starting with linux 4.12 our patch no longer applied. In order to
avoid having to maintain patches for different linux kernels it is
easier to use a wrapper instead.
