All patches in this commit were from Josef Drexler.

* Fixes a segfault when configure finds execinfo.h.

* Fix compile errors and warnings with g++ 4.3.x.

* Fixes an interoperability issue in the get_peers handling, now it
behaves according to the clarified BEP-0005. Also fixes a minor issue
of not being able to generate error packets.

* Fix a crash in scgi_local or scgi_port when calling freeaddrinfo
with a NULL pointer.

* Only check the filename cache for loading tied torrents (e.g. from
watch dirs) but not manually loaded ones via <enter>/<bs>, to allow
loading those again (ticket #1227).

* Fix display of multi-byte characters with attributes (i.e. utf-8
filenames in the file list), and make the list aware of characters
occupying two screen positions.
