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.

(cherry-picked from commit f54e09bc)

(cherry-picked from commit 7646aa98)

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.

This reverts commit 922a792b.

This reverts commit fdfab83c.

Samba3.4 is EOL for a long time and Samba4 is available so switch to it.

The original text was little bit cryptic and wasn't true in the end
because master is now considered v6.0 and this of course changes as we
go trough new versions. This should now explain reader how to get
specific version in more general terms.

This commit improves code for service enablement and restart in
base-files package. This is same code as in
