  Fixup: format strings for tap output

Before this patch tap output to a file fails with below error

 File "/usr/lib/python2.7/site-packages/avocado_framework-42.0-py2.7.egg/avocado/core/result.py", line 178, in check_test
    self.end_test(state)

  File "/usr/lib/python2.7/site-packages/avocado_framework-42.0-py2.7.egg/avocado/plugins/tap.py", line 69, in end_test
    self.__write("#   " + line)

  File "/usr/lib/python2.7/site-packages/avocado_framework-42.0-py2.7.egg/avocado/plugins/tap.py", line 35, in writeln
    return self.output.write(msg % args + "\n")

TypeError: not enough arguments for format string

This patch addresses above issue.

When running tests remotely, html plugin might be already present. Let's
remove the previously existing files to avoid failure and to always get
the latest results.

NOTE: We might want to re-consider whether to skip the html update, or
whether to always update results, but the current status is not optimal.

The joblogdir was added several years ago but it was not defined in
remote.test. Let's add it and use the local_job_logdir because this
variable is used during start_tests/start_test/end_test/... which could
make the local avocado to process files which does not exists or files
which does not belong to this job.

Besides the port of the TAP plugin, this makes the Result only
consider a test to have run after it finishes

The way the Result class has been accounting tests run is a
consequence of the implementation detail.  Before any tests are
actually run, that is, in `start_tests()`, the counter is incremented.
This is obviously wrong.

The counter should only be incremented at `end_test()`, which is
already done.  AFAICT, the current approach was working because the
subclasses of Result, such as HumanResult, would print the current
status on their own `end_test()`, and then only after that they would
call the parent (Result) `end_test()`.  This, together with the
reconcile method, seems to have kept the counters accurate to end
users, even when they were not accurate internally.

Even though Avocado already publishes an interface for result plugins
(in the avocado.core.plugin_interfaces module), that one is suitable
for plugins that will generate one output after the job as a whole
finishes.

There is another type of use case, already present in Avocado, but
still not implemented using the newer plugin mechanism.  The use
case is result plugins that must respond to events, some that come
from the job and some that come from tests.

The EventResult interface is a collection of Job interfaces that
would happen before tests start running (pre_tests and post_tests)
and events that are closer to the test themselves (start_test,
test_progress and end_test).

The new dispatcher calls plugins that implement the ResultEvents
interface.

This is the right place to criticize the test suite.  Even though I
don't feel it's right to abort the application from within the job
class, this prevents the current user experience to break.

In the near future, I'd like to see removed, and avocado runs without
a test suite to run and give these exact results: no tests were
available to be run, so none were executed.

The html plugin can only cope with finished results. Currently this is
not problem, because `render` is not called, but following patches adds
the possibility to postprocess results in such cases so let's prepare
for it.

A result has a 1:1 relation to a Job. To match one to the other the
job `unique_id` is saved to the result as `job_unique_id`.

The same way that a job alwayas was a unique_id, the result should
never miss the job_unique_id.  So, let's not try to hide or postpone
errors from such as scenario.

This change introduces what is going to be the only one result
instance to a job.  Instead of keeping track of the same information
on multiple plugins, plugins will refer to the unique job result
instance.

This changes does not remove the result proxy just yet, because by
doing so, the plugins that depend on it would cease to run.  Once
plugins are ported to use the unique result instance, the result proxy
will be removed.

Some tests might finish before producing any output, then the runner
should reflect that instead of IOError followed by hang because of

According to the test name RFC, once a test references goes though
the resolver, it becomes a test name.  When it's set to be run by
the runner, and to be recorded in the result, it becomes a test ID.

Since the JSON records the result, the `url` key is really misleading,
and it should be named `id` (as in test ID).

Compatibility has been kept, that is, the key named `url` still exists,
and can be removed in a future version.
Signed-off-by: NCleber Rosa <crosa@redhat.com>

Since we're renaming all of the mentions from URL to Test References, it also
makes sense to rename the `jobdata/urls` file to `jobdata/test_references`.

As compatibility measures, this tries to read the `urls` file when
`test_references` is not available (newer avocado and older jobdata) and
also adds a symlink from `test_referneces` to a link called `urls`, when
older avocado finds a newer jobdata.

It's been a while since the "Test ID RFC" came out:

https://www.redhat.com/archives/avocado-devel/2016-March/msg00024.html

Still, we've been referring to test URLs all around our code
and also on user visible strings.  This is an attempt to rename
the mentions of "URLs" that really should be "test references"
or simply "references" at this point.

Creating a test interactively is not entirely a use case we have
thought about, AFAICT, but it shouldn't fail because of an
implementation detail.

The implementation detail, in detail, is that the `filename` property
uses inspect to try to locate the file that backs
`avocado.core.test.Test` based tests.  The proposed change is that,
if inspect fails to find the file that backs the test, the tests'
`filename` property should resolve to None.

In practice, this allows the following snippets to be tried on the
Python interpreter:

  >>> import avocado
  >>> class Test(avocado.Test):
  ...     def test(self):
  ...         pass
  >>> t = Test()
