Disabled packages add unnecessary complexity and introduce no big gain.
Furthermore they might and do hide if package is fixed by upstream.

There are two reason why package can be disabled. Either id does not
compile because it is broken and in that case we should build it in hope
that it will be fixed. Or it might be because it just does not apply on
given board or architecture and in that case that package should be
marked as incompatible with that architecture in package itself not
somewhere outside.

In Linux 4.13, a new kernel option was introduced to allow userspace
access to RTC NVMEM. This option is off by default, making the NVMEM
inaccessable. Since there is at least one application utilizing it, this
patch adds `/sys/class/rtc/rtc0/device/nvram` back.

Fixes CVE-2019-14287

Now release tags have a correct date and include all release notes for that
particular release.

This reverts commit 1bd0f379.

This was created to migrate Turris OS 4.0-alpha* releases. The first
supported version 4.0-beta1 already contains correct path with board
specific path so there is no need to preserve these obsolete ones.
Non the less they are also wrong with additional introduced changes.
They point to pkglists in invalid location.

This requires also removal of code on build server to not use --obsolete
option and to not deploy those.

Patches are leaving some stuff behind, lets remove only Makefile

Remove mariadb from packages repository. Something broke
priority of feeds and even turrispackages is the highest one it
installs it from packages repository. We want newer version.

To force people to the wizard to set password.

Currently, we don't need it, yet. It also requires to set other options
related to this one, but let's postpone it.

This reverts commit 38d3be08.

Upstream renamed it to config.buildinfo.

They also introduced new file feeds.buildinfo. We could use that instead
of our git-hash generated file.
