The 'avocado list -V' prints the list of tests as a matrix with
Type, Test and Tag(s) columns. Some lines may get trailing
whitespace chars due the method used to align the columns' value.

Changed the call to avocado.utils.astring.iter_tabular_output()
so that trailing whitespace are removed from each row.

Adjusted the PluginsTest.test_list_no_file_loader() test due lack
of whitespace on outputs to be compared.

Added 'strip' parameter (default False) to avocado.utils.astring's
iter_tabular_output() and tabular_output() methods that strips
trailing whitespace of rows on the tabular output.

Also introduced unit tests for those methods.

test_run_sudo() actually needs sudo, because it attempts to run it.
Let's check for the file at the usual location, and skip the test
unless it exists.

Depending on the Python version stack being used *by inspekt*, it
can produce this error:

   Syntax check FAIL
   ************* Module avocado.utils.astring

Let's disable that check, since that variable is a reserved word
that should always exist in Python 2.7, for which a conditional
exists.

Some tests execute avocado directly, which uses "/usr/bin/env python" by
default. On distributions with py2 and py3 installed we might end-up
running those tests using python2 while running the main selftest by
python3.

With this change we need to make sure to pass the correct python binary
in UNITTEST_AVOCADO_CMD as it's not doing this by default (to allow any
avocado command).

The FDDrainer reads from process output and write to loggers.  The
test log, which is intended for humans, can indeed try to treat it as
text.  The stream logger, on the other hand, should deal with data as
binary content *only*, but this will be handled on a future change.

By having text content passed to the loggers, we avoid the occurrence
of log lines that look like:

  [stdout] b'command output'

Or output files (job-YYYY-MM-DDTHH.MM-id/tests/<test>/output) that
may literally contain:

  b'command output'

The encoding used is the one specified at the command execution.  With
this fix, a number of tests on Python 3 can now run successfully.

In the module global scope, "man echo" is executed to attempt to
determine if it's a GNU echo.  But, "man echo" in a locale such
as UTF-8 produces funky copyright characters:

  $ LANG=en_US.UTF-8 man echo | chardetect -
  <stdin>: windows-1252 with confidence 0.73

Which can not be decoded by the UTF-8 codec, producing
UnicodeDecodeErrors.  Even if that wasn't the case, it's better to
control the locale of command that can generate varied output, and
that we depend on.

  $ LANG=C man echo | chardetect -
  <stdin>: ascii with confidence 1.0

This change introduces the following requirement: the command to
be run by the avocado.utils.process functions should be given as unicode.
It brings a clearer interface, in which there's no need to deal with
encodings internally.

For simple test, it brings changes to respect the of passing unicode.
And, it changes the presentation of simple tests with unicode names
explicitly expreseed as such.

The way to deal with the process data that may be generated on
stdout/stderr is unchanged.

There's just so much implicit conversion on those methods that makes
them an enourmous source of errors (including UnicodeErrors).  The
information is still all there, and users are free to interpret them
as they see fit.

On the basis of the non-existence of the "true" command on the system
running tests.  Most of the tests do not even reference the "true"
command, and those that do, do not require the binary to exist, but
only a valid command line to be given.

In that aspect, a fictional command is used where needed.

The sudo related test are currently broken in the following aspects:

 1) it doesn't require TRUE_CMD
 2) the monkey patching of find_command() produces and adverse effect,
    and makes the binary we look for ("sudo") become "true"
 3) the expected results reflect the wrong sudo binary

Let's fix those aspects, making sure the process.py library looks for
sudo only, and that it prepends that (the found sudo binary) to the
generated command.

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.

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.
