chromium: Improve update script and update to latest versions.
Previously, we had a single hash of the whole version response from
omahaproxy.
Unfortunately the dev version is released quite frequently, so the hash
is of no use at all (we could rather directly fetch rather than
executing the script, because it will fetch all channels anyway).
This pull request adds two methods of caching:
* First of all, if a perticular version/channel is already in the
previous version of the sources.nix file, don't download it again.
* And the second method is to check if the current sha256 is already
downloaded and reads the corresponding sha256 from the lookup table.
So, this should really help to avoid flooding the download servers and
to not stress impatient users too much.
So, now even Firefox can be built with our shiny new fixed up NSS derivation,
and as this is desired (especially if we want to support certificates from the
CA bundle), let's make it the default.
Hurray! This is the first time chromium is working with NSS _and_ is able to
verify certificates using the root certificates built in into NSS.
Optimally it would use certs from OPENSSL_X509_CERT_FILE, but at least it's
working, so let's add that at some later point.
Until this commit we had a single hash of the whole version response from
omahaproxy. This worked well for not updating unnecessarily but only until one
single channel has a new version available.
Unfortunately the dev version is released quite frequently, so the hash is of no
use at all (we could rather directly fetch everything everytime we execute the
script).
This led to this commit, which adds two methods of caching:
First of all, if a perticular version/channel is already in the previous version
of the sources.nix file, don't download it again.
And the second method is to check if the current sha256 is already downloaded
and reads the corresponding sha256 from the lookup table.

The reason is because unpacking debian packages requires fewer dependencies (ar,
gzip and tar, nothing more), and in addition we can explicitly reference a
version number from the apt repository.
This caused HTML5 video to not work because this shared library is loaded at
runtime.
Unfortunately we can't use system ffmpeg yet, because upgrading would break
builds of other packages, and it would result in a copy of ffmpeg laying around
aswell, so we can defer this until we have fixed ffmpeg.
Thanks to @bluescreen303 for the bug report.
The configure script picks up libbsd.so from the host machine.
It uses simple find command to locate the file, but the linker
can not use it.
The fix replace the search path to /no-such-path
I switch off the build of ocaml compilers to native code, and add
a 'passthru' that unison can use to see if it needs to call the native
or the bytecode compiler.
As already promised, the old single-channel source.nix is now obsolete as we're
using Omahaproxy now and the build of the stable version finishes successful and
the browser runs fine.
The previos update script just used the last version of chromium that showed up
at the bucket list at:
http://commondatastorage.googleapis.com/chromium-browser-official/
I'm not sure which channel this list actually holds, so I'm going to switch now
using the official release channels grabbed by omahaproxy. This also has the
advantage that we can provide different versions/flavors of chromium.
We now also write our data to sources.nix instead of source.nix, as we have more
than one source.
Always did this manually by putting -j8 into make flags, which i didn't commit,
as it obviously doesn't make sense to hardcode. However, this flag makes more
sense and obviously we need to avoid overriding buildPhase.
