utils: add stoken

stoken is a tokencode generator compatible with RSA SecurID
128-bit (AES). stoken supports libtomcrypt and libnettle, we build
against nettle by default since tomcrypt is not packaged by OpenWrt

openconnect: add an option to support stoken

Add a new build configuration option for openconnect and let it link
against libstoken if instructed to. Two new uci configuration variables
are introduced: "token_mode" and "token_secret" to allow openconnect to
use those.

The former avahi service file was only installed for mpd-full. Does
the mpd-mini does not support network functionality?

Then we should adjust deps here...
