The names were changed:
* v4.0 -> hbk
* v4.1 -> hbl
* v5.0 -> hbd

Branch for-v4.0 was renamed to master and master to develop.

This reverts commit efbd0717.

It seems that upstream did not fix it nonetheless.

This moves version file generation right after clean. This ensures that
we really report OpenWrt hash and not our patch commit that is created
to extend ignore list.

This also uses different git command that has lower overhead and is
intended more for this kind of operation.

Change .asciidoc to more standard and shorter .adoc.

This potentially breaks some links to workflow in master from outside
but in general is has to happen to be consistent with other projects and
future changes in them.

The reason is that this is more appropriate if for example we modify
patches on commit not yet build but released older version. Such state
would not compile so instead we have to choose packages version. The
changes in updater's lists should not have such effect.

This installs blkdiscard and fstrim no matter on board.

This also removes resiserfs as upstream removed reiserfsprogs and only
kernel module is now present. In the end it makes no sense to have it in
lists as it is unusable.

It compiles for now, let's enable it.

This reverts commit 9a43c4ca.

I am able to compile it locally and buildbots in OpenWrt compiles it as
well.

This reverts commit 0857a679.

Turris 1.1 was missing USB3 driver for its front USB port.

turris-survey is not available in Turris OS 4.0 so it can't be
installed.

The patch is included in the kernel (master branch) and it was cherry-picked and included in
kernel 4.14.158.
