oga 5c402536fa group_ctx->name is only used in this one function, and for now it
corresponds directly to the static list of group names. Just use the
static list and stop strdup()ing a new version for the context struct.
Since that never got freed this also fixes a small memleak.

Kill some unused variables while i'm here.
