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

httpap is obsolete; we support privoxy directly now!

smtpap is obsolete; need to find a good socks4a-enabled smtp proxy/client

I dub thee 0.0.1.

(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?

(it seemed to work anyway, but...)


svn:r100

use 2**16+1 rather than 2**16 + 2**(-1)

the implementation is sort of a kludge..you're welcome to fix it up


svn:r94

the package is tor, the binary is or.

and i added our project plan to the todo file.

previously padding cells, etc were distinguishable because their body was
all zero's

this is a checkpoint before i fix the fact that port is always kept in
network order -- which makes no sense, because network order is different
on different machines, which is the whole point.

size_t is what you get back from sizeof(). no more, no less.

now it deals gracefully with too few connected routers (i think)

Added the crypto abstraction to libor. Need to test and change the code to use this instead of OpenSSL.
