The drm feature solves the problem of creating a common entry
point for adding kernel drm modules for different package lists.
The need for allocation into a separate feature arose from one
parties to the need to make a switch between free and proprietary
NVIDIA driver, on the other, because of the need to add only drm
modules kernels for purposes such as use/stage2/kms and use/plymouth.

Also no more switch needed for RADEON, as only the free video driver
remains.

- apply server-v 9.1 release patches (thanks shaba@)
- apply e2k patches (mike@)
- mipsel-bfk3: Fix /etc/fstab generation (thanks iv@)
- Rename all RPMs to canonical names before genbasedir (thanks boyars@)
- gnustep: Fix build
- oem: Add use/oem/no-cleanup
- deflogin: Now you can add a user with specific uid, gid and so on

Variable SPECIAL_USER must have the following format:
user:group:uid:gid:homedir:shell
Example:
@$(call set,SPEC_USER,user:user:500:500:/home/user:/bin/bash)

This bug was introduced in c310a1e9 and was
breaking bfk3 builds ever since.

This target disable cleanup install packages after finishing
alterator-setup.

Removed from Sisyphus.

So we added a separate target use/fonts/system.
Needed for kworkstation.

Firefox no longer supports preinstalling extensions.

use/fonts must be called every time you add something to the FONTS
variable.

This is following mkimage's approach;
better late than never.

`make clean' and `make distclean' use none of these,
no reason to spend extra forks, i/o and time.

Not that it's exported anyways!

This one is going to need adaptation for each private repo
but eventually should be gone in favour of sisyphus-mirror.

...so that it's discoverable to those curious to look into
package group list during installation; yes, it is pulled in
by mkimage, the sole purpose of this commit is advertising it. :)

alterator-users <= 10.12 and autologin-sh-functions <= 0.2.9
do not support proper multiseat autologin setup; let's at least
ask them to not confuse those installing multiseat systems with
"autologin" checkbox that will just break it (presuming single-
seat setup).

This one should ensure we can actually see propagator
(given dri/kms kernel drivers built as modules).
