Resolved problems with (re-)fetching hidden service descriptors.
Before, v0 descriptors were not fetched at all (fix on 0.2.0.18-alpha),
re-fetching of v2 descriptors did not stop when a v0 descriptor was
received (fix on 0.2.0.18-alpha), and re-fetching of v2 descriptors did
not work in all cases (fix on 0.2.0.19-alpha).

Fix all but 2 DOCDOC items; defer many XXX020s (particularly those where fixing them would fix no bugs at the risk of introducing some bugs).
svn:r13529
Bugfix from Karsten: "Reversed r13439; v2 rendezvous descriptors were only re-fetched when a directory connection did not finish, not when a directory correctly replied with an error code like 404; bug found by nwf.

Re-tune mempool parametes based on testing on peacetime: use smaller chuncks, free them a little more aggressively, and try very hard to concentrate allocations on fuller chunks. Also, lots of new documentation.
svn:r13484
Fix some XXX020s in command.c, and make it not-allowed to negotiate v1 using the v2 connection protocol: it is too hard to test, and pointless to support.
svn:r13460
More protocol negotiation work. Make the negotiation actually complete and set the state to open. Fix a crash bug that occured when we forcibly stopped the connection from writing.
svn:r13434
Add a bunch more code documentation; change the interface of fetch_var_cell_from_buf() so it takes the current link protocol into account and can't get confused by weird command bytes on v1 connections.
svn:r13430
Add a couple of (currently disabled) strategies for trying to avoid using too much ram in memory pools: prefer putting new cells in almost-full chunks, and be willing to free the last empty chunk if we have not needed it for a while. Also add better output to mp_pool_log_status to track how many mallocs a given memory pool strategy is saving us, so we can tune the mempool parameters.
svn:r13428
Fix some warnings identified by building with -D_FORTIFY_SOURCE=2. Remove a redundant (and nuts) definition of _FORTIFY_SOURCE from eventdns.c.
svn:r13424
Be more thorough about memory poisoning and clearing. Add an in-place version of aes_crypt in order to remove a memcpy from relay_crypt_one_payload.
svn:r13414
The SSL portion of the revised handshake now seems to work: I just finally got a client and a server to negotiate versions. Now to make sure certificate verification is really happening, connections are getting opened, etc.
svn:r13409
Add more documentation; change the behavior of read_to_buf_tls to be more consistent. Note a longstanding problem with current read/write interfaces.
svn:r13407
even when the local resolv.conf file is missing, broken, or contains
only unusable nameservers.
Now I can run a local network on my laptop when I'm on an airplane.
