avocado: Add NullHandler for early 'avocado.test' logger

So we avoid those annoying 'no handlers found for avocado.test'
during test.

Makefile: Add 'make check'

One convenient command to run the checks Travis runs on
the code base (less verbose version).

Refactoring unique job ID generation

Validate job ID

The previous implementation was mixing non-random information with
random data before applying a hash on top of everything. Given that,
we couldn't use the hash later to validate the information and the
entropy was limited to 64 bits, which was the random part.

So I've got rid of the sha1 code and just used a 160 random number.

A future improvement would be the use a random number in the first
part of the ID (a salt) and a hash of relevant information in the
second part. In pseudo-code:

    info = hostname, date, list of tests, etc
    salt =  str(hex(getrandbits(120)))[[2:-1]
    hash = sha1(info).hexdigest()[:10]
    return salt+hash

Includes a functional test to check the ID is indeed a 40 digit hex
number.

The name get_job_id() doesn't reflect the fact that this
function returns a new job ID everytime it's called.

Job ID needs to be a 40 digit hex number. Error out if it's not.

Includes functional tests

avocado.spec: Add Fabric dependency

It is not necessary to internally import the libraries like
we've been doing so far.

Virt test fixes

So that when we use io.log_line, files get written to
the appropriate test log locations.

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

Add string manipulation APIs to the avocado.utils namespace.

Add a library for functions with the same pattern: wait for
another function to evaluate to True, for a certain amount
of time.

So that we can do things such as killing an entire
process tree, necessary for aexpect functionality.

ctrl+c fixes

Also improve its documentation, explaining that users should
not use this option unless they know exactly what they're doing
Signed-off-by: NAdemar de Souza Reis Jr <areis@redhat.com>

Ctrl+C was aborting the current test, but avocado would keep
looping through the list provided in the command line.

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.

This is the tree we've been using in several of our discussions and
algorithm simulations.

Rename them from filter_out and filter_only to filter-out and filter-only,
respectively.

Motivation: consistent with original RFC and easier to the eyes, specially when
new filter keywords get added (filter-depth, filter-value, etc).
