Remove 10k per directory limitation

[dsnopek]

So, I know that having 10k objects in a directory isn't a good idea! :-) But I've got to deal with this server/application as it is for the time being.

The Cloud Files limitation is 10k per result set. My branch changes list_directory() to request the next set of objects if it gets exactly 10k results.

It does this by moving most of the functionality of list_directory() into list_directory_internal() with a slightly changed interface (the return value is the number of objects in the result set, and dir_list isn't cleared, it's used as the last item returned). Then in list_directory() it calls list_directory_internal(), looping if necessary.

It's been a long time since I've written any C code, so I hope didn't do anything really stupid in there! In any case, go easy on me. ;-)

Best regards, David.
