* Improved error handling for settings. LibTorrent now consistently

throws torrent::input_error and rtorrent catches those and prints good
error messages.

* torrent::set_{bind,local}_address now accepts dns addresses.

* Fixed bug that caused multiple instances of the setting
up/download_rate to change the relative rate, rather than constant.

* Minor change to the way PCB decides to not request more pieces.
