Add aexpect, a near exact copy of the code that
has been used by virt-test for a long time. It
is a library for controlling interactive process,
similar to pexpect, but with some additional
properties:

* Programs may stay alive between tests and jobs
* More sophisticated class structure

We frequently need to generate data for framework or
testing purposes. Introducing data_factory, a library
dedicated to this purpose.

With this, we can make other parts of avocado to use
it and supersede old functions used on this regard.

manpage: update based on recent command line and plugin changes

avocado.plugins: Fix bug 'Namespace' object has no attribute

This syncs the manpage with the latest changes of command line options
and plugins (for example, the new multiplex).

Fix problem when running Avocado with subcommand other than run:

$ avocado plugins
Could not activate plugin 'run_vm': 'Namespace' object has no attribute 'vm'
Could not activate plugin 'json': 'Namespace' object has no attribute 'json_output'
Could not activate plugin 'xunit': 'Namespace' object has no attribute 'xunit_output'
Could not activate plugin 'journal': 'Namespace' object has no attribute 'journal'
Plugins loaded:
    datadir      - Implements the avocado 'datadir' subcommand (Enabled)
    json         - JSON output (Enabled)
    journal      - Test journal (Enabled)
    multiplexer  - Implements the avocado 'multiplex' subcommand. (Enabled)
    plugins_list - Implements the avocado 'plugins' subcommand (Enabled)

Move options to test runner,  plugins has priority and app parser has the test runner parser

Fix functional tests regarding the changes that moves
options from the main application to the test runner (avocado run).

Move plugins journal, json, xunit and vm inside the test runner
subcommand, now the command line options belongs to the runner,
instead of the main application.

Export the test runner parser back to the main parser,
so you can use `parser.runner` to extend it.

Add priority when loading plugins (both built-in or external).
The lowest the priority (0 by default) then earliest the plugin will
be loaded.

In the current implementation, only the runner plugin has
priority 0 and the other plug-ins are all defined as priority 3.

test progress API: removed simplistic check_progress() idea

The check_progress() idea is too simplistic for what we aim for,
so let's remove it to prevent test writers from depending on it.

Also, rename communicate_state() to report_state().

Trivial fixes sprint12

In avocado, we use 'less' for a paginator. When one presses
'q' in the paginator, an IOError is raised (the subprocess
opened with os.popen has just quit), so let's introduce a
Paginator class, that can handle cleanly 'q' without asking
API users to handle the exception themselves.

avocado.cli.parser: New way to parsing arguments.

The parser for the subcommand run now accepts one or more
tests ids (paths / aliases) and there isn't a need to quote the list
as a string.

Example:

* Before: avocado 'sleeptest failtest /usr/bin/true'
* Now: avocado sleeptest failtest /usr/bin/true

So it's now possible to run avocado like `avocado run *.py`.
