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

chg: make "get default sockdir" a separate method The logic to get a default socket directory will become longer in the next patch. So let's move it out.

chg: handle connect failure before errno gets overridden This patch moves the error handling logic up so that errno after connect won't be overridden.

py3: have a bytes version of shlex.split() shlex.split() only accepts unicodes on Python 3. After this patch we will be using pycompat.shlexsplit(). This patch also replaces existing occurences of shlex.split with pycompat.shlexsplit.

chg: support long socket path This patch replaces UNIX_PATH_MAX (108) with PATH_MAX (4096) so we can have long unix path.

chg: remove sockdirfd See the previous patch for the reason.
