Since we are not using __dir__ anymore to list the available properties,
the OrderedDict is not needed. And dropping it makes the performance to
improve.

For small classes, like this one, with known attributes, using dict
wastes a lot of RAM. Defining __slots__ as a list will save a lot of
memory, while improving the performance a bit.

We loose in flexibility by the performance improvement justifies the
change. Since __getattr__ is the last resource python tries to solve
attributes, creating the actual properties makes the resolution to
happen earlier and the performance to be way better.

Instead of using regex to parse the `data`, let's use a simpler and more
performatic version witch just handles the last character to figure out
the unit.

There are few issues (3 to my count) which affect a number of tests
on Python 3.  Instead of not executing any of the functional tests,
let's skip the broken ones.

This is important because it will prevent new issues from making
its way into the Avocado code.

The list of tests being skipped is being tracked on our planning board,
so that they are accounted for, and enabled when fixed.

Some tests might produce too much logs which might result in too big
xunit results, that might be hard/impossible to publish. Let's allow
setting a limit to number of characters to those files and embed only
1/2 of the limit from the beginning and 1/2 of the limit from the end of
the log.

As it was done in d2b4edc3, Python 3.4 needs a string to be passed to
json.loads() (and, indirectly, to json.load()).  Different from
d2b4edc3, the content we fetch externally may be able to tell us the
encoding that is used.

Let's use that information, if available, to decode the stream of
bytes into a string that is acceptable to json.loads().

The Python dependencies are already tracked by the python2 or python3

automatic requires/provides scanner.

Before this change, a query for the requirements of the Python 2 package
would reveal:

    /usr/bin/python2
