aae034d13e Write a bunch of module documentation. 
This commit adds or improves the module-level documenation for:

  buffers.c circuitstats.c command.c connection_edge.c control.c
  cpuworker.c crypto_curve25519.c crypto_curve25519.h
  crypto_ed25519.c crypto_format.c dircollate.c dirserv.c dns.c
  dns_structs.h fp_pair.c geoip.c hibernate.c keypin.c ntmain.c
  onion.c onion_fast.c onion_ntor.c onion_tap.c periodic.c
  protover.c protover.h reasons.c rephist.c replaycache.c
  routerlist.c routerparse.c routerset.c statefile.c status.c
  tor_main.c workqueue.c

In particular, I've tried to explain (for each documented module)
what each module does, what's in it, what the big idea is, why it
belongs in Tor, and who calls it.  In a few cases, I've added TODO
notes about refactoring opportunities.

I've also renamed an argument, and fixed a few DOCDOC comments.

fcdcb377a4 Add another year to our copyright dates. 
Because in 95 years, we or our successors will surely care about
enforcing the BSD license terms on this code.  Right?

d6e6eaba60 Fix windows compilation of e0c8031516 
There is no WSAEPERM; we were implying that there was.This fixes a
bug in e0c8031516, which hadn't yet
appeared in any released Tor.

2b6e91c2ee Report EADDRNOTAVAIL and EADDRINUSE as RESOURCELIMIT 
These errors usually mean address exhaustion; reporting them as such
lets clients adjust their load to try other exits.

Fix for bug 4710; bugfix on 0.1.0.1-rc, which started using
END_STREAM_REASON_RESOURCELIMIT.

5cf9167f91 Use the standard _WIN32, not the Torism MS_WINDOWS or deprecated WIN32 
This commit is completely mechanical; I used this perl script to make it:

 #!/usr/bin/perl -w -i.bak -p

 if (/^\s*\#/) {
     s/MS_WINDOWS/_WIN32/g;
     s/\bWIN32\b/_WIN32/g;
 }

411ec3c0f8 Add client code to detect attempts to connect to 127.0.0.1 etc 
We detect and reject said attempts if there is no chosen exit node or
circuit: connecting to a private addr via a randomly chosen exit node
will usually fail (if all exits reject private addresses), is always
ill-defined (you're not asking for any particular host or service),
and usually an error (you've configured all requests to go over Tor
when you really wanted to configure all _remote_ requests to go over
Tor).

This can also help detect forwarding loop requests.

Found as part of bug2279.

311aca5a34 Log bandwidth_weight_rule_t as a string, not an integer. 
I'm adding this because I can never remember what stuff like 'rule 3'
means.  That's the one where if somebody goes limp or taps out, the
fight is over, right?

c4b8fef362 Remove svn $Id$s from our source, and remove tor --version --version. 
The subversion $Id$ fields made every commit force a rebuild of
whatever file got committed.  They were not actually useful for
telling the version of Tor files in the wild.
