contrib: add a set of scripts to run pytype in Docker

Having a simple way to run pytype for developers can massively shorten
development cycle. Using the same Docker image and scripts that we use on our
CI guarantees that the result achieved locally will be very similar to (if not
the same as) the output of our CI runners.

Things to note: the Dockerfile needs to do a little dance around user
permissions inside /home/ci-runner/ because:

- on one hand, creating new files on the host (e.g. .pyi files inside .pytype/)
  should use host user's uid and gid

- on the other hand, when we run the image as uid:gid of host user, it needs to
  be able to read/execute files inside the image that are owned by ci-runner

Since local user's uid might be different from ci-runner's uid, we execute this
very broad chmod command inside /home/ci-runner/, but then run the image as the
host user's uid:gid.

There might be a better way to do this.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install::

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing::

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.

Notes for packagers
===================

Mercurial ships a copy of the python-zstandard sources. This is used to
provide support for zstd compression and decompression functionality. The
module is not intended to be replaced by the plain python-zstandard nor
is it intended to use a system zstd library. Patches can result in hard
to diagnose errors and are explicitly discouraged as unsupported
configuration.
