9260a824ef Yet another buffer RAM patch: tNever ever ever keep a buffer memory chunk around for an empty buffer that could go on the freelist. This wants profiling to make sure that performance doesnt suffer.

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.)

Sun CC likes to give warnings for the do { } while(0) construction for making statement-like macros.  Define STMT_BEGIN/STMT_END macros that do the right thing, and use them everywhere.

30e4f4f6ce when we're doing a write split over the end of a circular 
buffer, make sure our tls_get_forced_write_size doesn't
make it write whatever's after the buffer.

this hasn't triggered yet, but it would be rare, so let's
leave it in.

0dbf725927 Infrastructure to test BEGIN_DIR cells. 
New socks command CONNECT_DIR. New config option TunnelDirConns that
builds a circ ending at the directory server and delivers a BEGIN_DIR
cell if it's running 0.1.2.2-alpha or later. We still need to make
one-hop circs when appropriate, while making other conns avoid them.
