server use this new protocol, they will use far less bandwidth (up
to 94% less) to keep the client's consensus up-to-date. Implements

- Tor can now compress directory traffic with lzma or with zstd
compression algoritms, which can deliver better bandwidth
compression algorithms, which can deliver better bandwidth
performance. Because lzma is computationally expensive, it's only
used for documents that can be compressed once and served many
times. Support for these algorithms requires that tor is build
times. Support for these algorithms requires that tor is built
with the libzstd and/or liblzma libraries available. Implements
proposal 278; closes ticket 21662.
- Relays now perform the more expensive compression operations, and
consensus diff generation, in worker threads. This separation
avoids delaying the main thread when a new consensus arrives.

get excited yet: currently, there is no actual Rust functionality
beyond some simple glue code, and a notice at startup to tell you
that Rust is running. Still, we hope that programmers and
packagers will try building Tor with rust support, so that we can
find issues, and solve portability problems. Closes ticket 22106.

not resist specialized eavesdroppers, but it should be enough to
make many ISPs' routine network flow logging less useful in
traffic analysis against Tor users.
