Here, have some terribly clever new buffer code.  It uses a mbuf-like strategy rather than a ring buffer strategy, so it should require far far less extra memory to hold any given amount of data.  Also, it avoids access patterns like x=malloc(1024);x=realloc(x,1048576);x=realloc(x,1024);append_to_freelist(x) that might have been contributing to memory fragmentation.  I've  tested it out a little on peacetime, and it seems to work so far.  If you want to benchmark it for speed, make sure to remove the #define PARANOIA; #define NOINLINE macros at the head of the module.

e5885deab5 Separate "SOCKS_COMMAND_CONNECT_DIR" into two flags in 
edge_connection_t: want_onehop if it must attach to a circuit with
only one hop (e.g. for the current tunnelled connections that use
begin_dir), and use_begindir if we mean to use a BEGIN_DIR relay
command to establish the stream rather than the normal BEGIN. Now
we can make anonymized begin_dir connections for (e.g.) more secure
hidden service posting and fetching.

Weasel noticed that many buffers spend their time with empty 4k, 8k, and 16k memory chunks.  Thus, be more aggressive about putting empty chunks on the freelist, regardless of their high water marks.  (Also, run buffer_shrink_freelist on the 8k-chunk freelist.)
