keepalive: remove limit argument from readline() It is unused and adds complexity.

keepalive: don't concatenate strings when reading chunked transfer Surprisingly, this didn't appear to speed up HTTP-based stream cloning on my machine. I suspect this has more to do with the fact we're using small HTTP chunks and string concatenation overhead isn't so bad. However, the reasons for this change are solid: we know string concatenation can be a performance sink.

exchange: use rich class for sorting clone bundle entries Python 3 removed the "cmp" argument from sorted(). Custom sorting in Python 3 must be implemented with the dunder comparison methods on types and/or with a "key" function. This patch converts our custom "cmp" function to a custom type. The implementation is very similar to functools.cmp_to_key(). However, cmp_to_key() doesn't exist in Python 2, so we can't use it. This was the only use of the "cmp" argument to sorted() in the code base.

chg: respect XDG_RUNTIME_DIR $XDG_RUNTIME_DIR [1] is a better place for user daemons. Let's use it and fallback to $TMPDIR. After this patch, chg will try socket paths in the following order: 1. $CHGSOCKNAME 2. $XDG_RUNTIME_DIR/chg/server 3. ${TMPDIR:-tmp}/chg$UID/server [1]: https://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html
