readd the decoder's name to the description of the config entry, but do

it right this time: use a different pointer for every decoder by putting the
descriptions into a dynamically growing chunk of heap memory
the name of the decoder in the description is necessary, because frontends
should not have to display the config entry key and this is currently the only
string to contain the decoder's name
