pyclock: Append gmenu2x to dependencies instead of overriding them

In practice this is never a problem because pygame is only a runtime
dependency and not a compile time dependency and Config.in contains
the same dependency.
Freeze etna_viv and mesa3d-etna_viv versions for release
od-network-config: Add package

This allows the user to set a password for logging in. It requires the
use of a shadow password database.

The implementation is in this repo. If it grows larger we might have to
create a dedicated repo for it.

The code was written by me, the icon was drawn by hi-ban.
opendingux: GCW0: Allow anonymous FTP if empty root password is set

A wrapper script checks the root password and if empty, it will pass
an additional config file to vsftpd which enables anonymous access.

The wrapper also allows adding a local config file by the user.
opendingux: GCW0: Make media dir in ftphome read-only

If the user accidentally tries to upload to the media dir, he/she will
get an error saying the directory is not writable, instead of getting
a disk full situation on the ramdisk that the media dir resides in.
dropbear: Add config option to allow logins with blank password
opendingux: GCW0: defconfig: Updated

Include od-network-config.
Allow blank password in dropbear.
