remove bandwidth negotation from the code

we still use bandwidth on a per-connection basis for rate
limiting. but it's unclear if we need this infrastructure in
addition to the total-bandwidth rate limiting that we also do.
i'll leave both infrastructures in, and we'll remove the
per-connection one if it starts rotting too much.

Get directories working.
...
Or at least, directories get generated, signed, download, and checked, with
nobody seeming to crash.
In config/*, added 'signing-key' blocks to dirservers and routers.or, so
that everyone will know about the directories' signing keys.
In or/directory.c, refrained from using a dirserver's signing key when
no such key is known; added more debugging output.
In or/main.c, added debugging output and fixed a few logic errors.
In or/routers.c, added debugging output and prevented a segfault on
routers_resolve_directory. The interleaving of arrays and lists on
routerinfo_t is still messy, but at least it seems to work again.
