The font configuration is now the responsibility of
software/headless-chromium, and any other software releases that wish
to use component/headless-chromium.

This is necessary because Chromium needs to think that the Host header
is an IP address (for security reasons), but the browser needs to think
that the Host header is a domain name (for TLS purposes). The easiest
way to do this is to use the Nginx http_sub module, but this isn't
enabled in the default SlapOS Nginx build.

The nginx proxy configuration now works with websockets. It's now possible to use the remote debugging port from another machine! Note that you'll need to manually change the ws=[ip:port] parameter in the URL to wss=[server-cdn-url] still. I will see if I can patch the frontend page to not require this, but I wanted to commit a working version first.

Cloning the full source tree rather than just a snapshot at the desired
version does increase the size of the checkout, but not as much as
originally feared. It goes from 25 GB -> 31 GB, which is manageable.
On the other hand, this allows some automated tools to figure out the
commit hashes from the repository history, which prevents the frontend
from complaining.

I plan to clean up the buildout file in the future, but I just wanted
to commit a known-working version.

Also improve the recipe `switch-softwaretype' by catching the possible errors.

This is based on commit "Firefox Version Up to 78.1.0esr", but it does not
replace the default firefox, just enable a new version for now.

This is a "minimal" version up to fix https://bugs.gentoo.org/580392 which
appears now that we build with gbm

some components, like binary chromium needs libgbm, which is part of mesa, but
build only when enabled.
