revamped the router reading section
reference counting for crypto pk env's (so we can dup them)
we now read and write pem pk keys from string rather than from FILE*,
in anticipation of fetching directories over a socket
(so now on startup we slurp in the whole file, then parse it as a string)
fixed a bug in the proxy side, where you could get some circuits
wedged if they showed up while the connection was being made
svn:r110
(hey nick, does this break the os x build?)
you still need to add some stuff to the ./configure commandline...
anybody know a better solution?
svn:r101
Note that there are new keywords in these, etc. Matej, would you be
interested in going through and patching routers.c, config.c, etc, so
they're cleaner?
