6b79d8a7e9 Two-pronged attack at my overzealous skew fixes.
The problem was that the fixes had us generating TLS certs with a
2-day lifetime on the assumption that we'd rotate fairly often.  In
fact, we never rotate our TLS keys.

This patch fixes the situation in 2 ways:
   1. It bumps the default lifetime back up to one year until we get
      rotation in place.
   2. It changes tor_tls_context_new() so that it doesn't leak memory
      when you call it more than once.

7604cfe61b Clock skew fixes.
Allow some slop (currently 3 minutes) when checking certificate validity.

Change certificate lifetime from 1 year to 2 days.  Since we
regenerate regularly (we regenerate regularly, right??), this
shouldn't be a problem.

Have directories reject descriptors published too far in the future
(currently 30 minutes).  If dirservs don't do this:
    0) Today is January 1, 2000.
    1) A very skewed server publishes descriptor X with a declared
       publication time of August 1, 2000.
    2) The directory includes X.
    3) Because of certificate lifetime issues, nobody can use the
       skewed server.
    4) The server fixes its skew, and goes to republish a new descriptor Y
       with publication time of January 1, 2000.
    5) But because the directory already has a "more recent" descriptor X,
       it rejects descriptor "Y" as superseded!

This patch should make step 2 go away.

3b5191d36d various bugfixes and updates
redo all the config files for the new format (we'll redo them again soon)

fix (another! yuck) segfault in log_fn when input is too large
tor_tls_context_new() returns -1 for error, not NULL
fix segfault in check_conn_marked() on conn's that die during tls handshake

make ORs also initialize conn from router when we're the receiving node

make non-dirserver ORs upload descriptor to every dirserver on startup
add our local address to the descriptor
add Content-Length field to POST command
revert the Content-Length search in fetch_from_buf_http() to previous code
fix segfault in memmove in fetch_from_buf_http()
raise maximum allowed headers/body size in directory.c

3d4ccb781a Refactor buffers; implement descriptors.
'buf_t' is now an opaque type defined in buffers.c .

Router descriptors now include all keys; routers generate keys as
needed on startup (in a newly defined "data directory"), and generate
their own descriptors.  Descriptors are now self-signed.

Implementation is not complete: descriptors are never published; and
upon receiving a descriptor, the directory doesn't do anything with
it.

At least "routers.or" and orkeygen are now obsolete, BTW.
