README / www-index overhaul

- Nuke old README in its entirety:

    - We don't want people using demos if possible, stop advertising them
    - Nix a bunch of bits that will now be replaced by standard PyPI sidebar links (docs, tests etc)
    - Ditto the 'headers', most of that stuff is either PyPI metadata or the about to be added shields.io badges
    - Some stuff deleted was also just old, eg IRC is no longer a support channel and I think librelist is dead too

- Rip out www site index for use as README and inject back in via
include
- Rewrite a bunch of that too for clarity
- Leverage it in long_description too

-What
-----
-
-"Paramiko" is a combination of the Esperanto words for "paranoid" and
-"friend".  It's a module for Python 2.7/3.4+ that implements the SSH2 protocol
-for secure (encrypted and authenticated) connections to remote machines. Unlike
-SSL (aka TLS), SSH2 protocol does not require hierarchical certificates signed
-by a powerful central authority.  You may know SSH2 as the protocol that
-replaced Telnet and rsh for secure access to remote shells, but the protocol
-also includes the ability to open arbitrary channels to remote services across
-the encrypted tunnel (this is how SFTP works, for example).
-
-It is written entirely in Python (though it depends on third-party C wrappers
-for low level crypto; these are often available precompiled) and is released
-under the GNU Lesser General Public License (`LGPL
-<https://www.gnu.org/copyleft/lesser.html>`_).
-
-The package and its API is fairly well documented in the ``docs`` folder that
-should have come with this repository.
-
-
-Installation
-------------
-
-For most users, the recommended method to install is via pip::
-
-    pip install paramiko
-
-For more detailed instructions, see the `Installing
-<http://www.paramiko.org/installing.html>`_ page on the main Paramiko website.
-
-
-Portability Issues
-------------------
-
-Paramiko primarily supports POSIX platforms with standard OpenSSH
-implementations, and is most frequently tested on Linux and OS X.  Windows is
-supported as well, though it may not be as straightforward.
-
-Bugs & Support
---------------
-
-:Bug Reports:  `Github <https://github.com/paramiko/paramiko/issues/>`_
-:Mailing List: ``paramiko@librelist.com`` (see the `LibreList website
-               <http://librelist.com/>`_ for usage details).
-:IRC:          ``#paramiko`` on Freenode
-
-
-Kerberos Support
-----------------
-
-Paramiko ships with optional Kerberos/GSSAPI support; for info on the extra
-dependencies for this, see the `GSS-API section
-<http://www.paramiko.org/installing.html#gssapi>`_
-on the main Paramiko website.
-
-
-Demo
-----
-
-Several demo scripts come with Paramiko to demonstrate how to use it.
-Probably the simplest demo is this::
-
-    import base64
-    import paramiko
-    key = paramiko.RSAKey(data=base64.b64decode(b'AAA...'))
-    client = paramiko.SSHClient()
-    client.get_host_keys().add('ssh.example.com', 'ssh-rsa', key)
-    client.connect('ssh.example.com', username='strongbad', password='thecheat')
-    stdin, stdout, stderr = client.exec_command('ls')
-    for line in stdout:
-        print('... ' + line.strip('\n'))
-    client.close()
-
-This prints out the results of executing ``ls`` on a remote server. The host
-key ``b'AAA...'`` should of course be replaced by the actual base64 encoding of the
-host key.  If you skip host key verification, the connection is not secure!
-
-The following example scripts (in demos/) get progressively more detailed:
-
-:demo_simple.py:
-    Calls invoke_shell() and emulates a terminal/TTY through which you can
-    execute commands interactively on a remote server.  Think of it as a
-    poor man's SSH command-line client.
-
-:demo.py:
-    Same as demo_simple.py, but allows you to authenticate using a private
-    key, attempts to use an SSH agent if present, and uses the long form of
-    some of the API calls.
-
-:forward.py:
-    Command-line script to set up port-forwarding across an SSH transport.
-
-:demo_sftp.py:
-    Opens an SFTP session and does a few simple file operations.
-
-:demo_server.py:
-    An SSH server that listens on port 2200 and accepts a login for
-    'robey' (password 'foo'), and pretends to be a BBS.  Meant to be a
-    very simple demo of writing an SSH server.
-
-:demo_keygen.py:
-    A key generator similar to OpenSSH ``ssh-keygen(1)`` program with
-    Paramiko keys generation and progress functions.
-
-Use
----
-
-The demo scripts are probably the best example of how to use this package.
-Also a lot of documentation is generated by Sphinx autodoc, in the
-doc/ folder.
-
-There are also unit tests here::
-
-    $ pip install -r dev-requirements.txt
-    $ pytest
-
-Which will verify that most of the core components are working correctly.
-
-To test Kerberos/GSSAPI, you need a Kerberos environment. On UNIX you can
-use the package k5test to setup a Kerberos environment on the fly::
-
-    $ pip install -r dev-requirements.txt
-    $ pip install k5test gssapi pyasn1
-    $ pytest
+Welcome to Paramiko!
+====================
+
+Paramiko is a pure-Python [#]_ (2.7, 3.4+) implementation of the SSHv2 protocol
+[#]_, providing both client and server functionality. It provides the
+foundation for the high-level SSH library `Fabric <https://fabfile.org>`_,
+which is what we recommend you use for common client use-cases such as running
+remote shell commands or transferring files.
+
+Direct use of Paramiko itself is only intended for users who need
+advanced/low-level primitives or want to run an in-Python sshd.
+
+For installation information, changelogs, FAQs and similar, please visit `our
+main project website <https://paramiko.org>`_; for API details, see `the
+versioned docs <https://docs.paramiko.org>`_. Additionally, the project
+maintainer keeps a `roadmap <http://bitprophet.org/projects#roadmap>`_ on his

+.. [#]
+    Paramiko relies on `cryptography <https://cryptography.io>`_ for crypto
+    functionality, which makes use of C and Rust extensions but has many
+    precompiled options available. See `our installation page
+    <https://www.paramiko.org/installing.html>`_ for details.
+
+.. [#]
+    SSH is defined in :rfc:`4251`, :rfc:`4252`, :rfc:`4253` and :rfc:`4254`. The
+    primary working implementation of the protocol is the `OpenSSH project

+    feature set, but there are occasional gaps.
