Comment (by lmfe):

 The first patch is, say, a refactoring of the current code. It's not
 really a refactoring, but more to keep things somewhat consistent and
 clearer.
 I found that there are actually two ways for autocomplete, and the two are
 #ifdef'ed, and have completely different behavior. The structure
 PidginCompletionData didn't even existed in the new style completion. This
 caused some functions having different signatures, depending on the #ifdef
 branch (take for example add_completion_list).

 In this first patch, what I did was:[[BR]]
 * Created the PidginCompletionData structure in both #ifdef
 branches.[[BR]]
 * Added some more fields to this structure.[[BR]]
 * Get rid of the 2-position arrays that were being passed as callback
 data, and used the PidginCompletionData for callbacks instead.
