Keenan Johnson 321b30ca56 extmod/modtls_mbedtls: Wire in support for DTLS.
This commit enables support for DTLS, i.e. TLS over datagram transport
protocols like UDP.  While support for DTLS is absent in CPython, it is
worth supporting it in MicroPython because it is the basis of the
ubiquitous CoAP protocol, used in many IoT projects.

To select DTLS, a new set of "protocols" are added to SSLContext:
- ssl.PROTOCOL_DTLS_CLIENT
- ssl.PROTOCOL_DTLS_SERVER

If one of these is set, the library assumes that the underlying socket is a
datagram-like socket (i.e. UDP or similar).

Our own timer callbacks are implemented because the out of the box
implementation relies on `gettimeofday()`.

This new DTLS feature is enabled on all ports that use mbedTLS.

This commit is an update to a previous PR #10062.

Addresses issue #5270 which requested DTLS support.

MicroPython Documentation

The MicroPython documentation can be found at: http://docs.micropython.org/en/latest/

The documentation you see there is generated from the files in the docs tree: https://github.com/micropython/micropython/tree/master/docs

Building the documentation locally

If you're making changes to the documentation, you may want to build the documentation locally so that you can preview your changes.

Install Sphinx, and optionally (for the RTD-styling), sphinx_rtd_theme, preferably in a virtualenv:

 pip install sphinx
 pip install sphinx_rtd_theme

In micropython/docs, build the docs:

make html

You'll find the index page at micropython/docs/build/html/index.html.

Having readthedocs.org build the documentation

If you would like to have docs for forks/branches hosted on GitHub, GitLab or BitBucket an alternative to building the docs locally is to sign up for a free https://readthedocs.org account. The rough steps to follow are:

  1. sign-up for an account, unless you already have one
  2. in your account settings: add GitHub as a connected service (assuming you have forked this repo on github)
  3. in your account projects: import your forked/cloned micropython repository into readthedocs
  4. in the project's versions: add the branches you are developing on or for which you'd like readthedocs to auto-generate docs whenever you push a change

PDF manual generation

This can be achieved with:

make latexpdf

but requires a rather complete install of LaTeX with various extensions. On Debian/Ubuntu, try (1GB+ download):

apt install texlive-latex-recommended texlive-latex-extra texlive-xetex texlive-fonts-extra cm-super xindy
