Todd Fiala 49d3c15c3e test infra: move test event-related handling into its own package
This change moves all the test event handling and its related
ResultsFormatter classes out of the packages/Python/lldbsuite/test dir
into a packages/Python/lldbsuite/test_event package. Formatters are
moved into a sub-package under that.

I am limiting the scope of this change to just the motion and a few
minor issues caught by a static Python checker (e.g. removing unused
import statements).

This is a pre-step for adding package-level tests to the test event
system. I also intend to simplify test event results formatter selection
after I make sure this doesn't break anybody.

Todd Fiala ca5793ea5c test infra cleanup: convert test_runner lib into package
Also does the following:
* adopts PEP8 naming convention for OptionalWith class (now
  optional_with).
* moves test_runner/lldb_utils.py to lldbsuite/support/optional_with.py.
* packages tests in a subpackage of test_runner per recommendations in
  http://the-hitchhikers-guide-to-packaging.readthedocs.org/en/latest/creation.html

Tests can be run from within pacakges/Python/lldbsuite/test via this
command:

  python -m unittest discover test_runner

The primary cleanup this allows is avoiding the need to muck with the
PYTHONPATH variable from within the source files.  This also aids some
of the static code checkers as they don't need to run code to determine
the proper python path.

Todd Fiala 430309f13a fix a race is the LLDB test suite results collection
The race boiled down to this:

If a test worker queue is able to run the test inferior and
clean up before the dosep.py listener socket is spun up, and
the worker queue is the last one (as would be the case when
there's only one test rerunning in the rerun queue), then
the test suite will exit the main loop before having a chance
to process any test events coming from the test inferior or
the worker queue job control.

I found this race to be far more likely on fast hardware.
Our Linux CI is one such example.  While it will show
up primarily during meta test events generated by
a worker thread when a test inferior times out or
exits with an exceptional exit (e.g. seg fault), it only
requires that the OS takes longer to hook up the
listener socket than it takes for the final test inferior
and worker thread to shut down.

The '-p' option for dotest.py was ignored in multiprocess mode,
as the -p argument to the inferior would overwrite the -p argument

Summary:
This adds ability to mark test that do not complete due to hangs, crashes, etc., as "expected",
to avoid flagging the build red for a known problem. Functionally, this extends the scope of the
existing expectedFailureXXX decorators to cover these states as well. Once this is in, I will
start replacing the magic list of failing tests in dosep.py with our regular annotations which
should hopefully make code simpler.

Todd Fiala 685a7570ec test infra: enable single-worker rerun phase for flakey tests.
Use of --rerun-all-issues will enable any test method failure, not just
test methods marked with the flakey decorator, to rerun.

Currently this does not change the flakey logic's immediate rerun
attempt.  I want to make sure this doesn't cause any significant issues
before changing that part.

The rerun reporting is only known to work properly with the
default (new) BasicResultsFormatter reporting.  Once we work out
any issues, I'll go back and make sure the curses output handles
it properly as well.

Todd Fiala 5183147e2d wire timeouts and exceptional inferior process exits through the test event system
The results formatter system is now fed timeouts and exceptional process
exits (i.e. inferior dotest.py process that exited by signal on POSIX
systems).

If a timeout or exceptional exit happens while a test method is running
on the worker queue, the timeout or exceptional exit is charged and
reported against that test method.  Otherwise, if no test method was
running at the time of the timeout or exceptional exit, only the test
filename will be reported as the TIMEOUT or ERROR.

Todd Fiala 46a4e34dcc Adds candidate formatter for replacing legacy summary results.
Also cleans up some usages of strings where symbolic names
were safer and made more sense.

Try a test run with something like this to check out the new
basic results formatter (not used by default):

time test/dotest.py --executable `pwd`/build/Debug/lldb --results-formatter lldbsuite.test.basic_results_formatter.BasicResultsFormatter --results-file stdout

This will yield something like:

Testing: 1 test suites, 8 threads
1 out of 1 test suites processed - TestHelp.py
Test Results
Total Test Methods Run (excluding reruns): 13
Test Method rerun count: 0

The Details header only prints if there are any issues to report.  The
Details section has tags that should get picked up using the normal
issue text scrapers (e.g. buildbot).

Test numbers reported are strictly test method runs.

The rerun bit at the top is in support of the multi-pass test
runner code (to run the low-load, single worker test pass for
tests that failed the first run), which I'll be able to put up
for review after this.

ResultsFormatters now have the ability to indicate they replace
the legacy summary, as this one does.

Once we come to agreement on the exact format, I will switch
us over to using this by default.

Zachary Turner c1b7cd72db Python 3 - Turn on absolute imports, and fix existing imports.
Absolute imports were introduced in Python 2.5 as a feature
(e.g. from __future__ import absolute_import), and made default
in Python 3.

When absolute imports are enabled, the import system changes in
a couple of ways:

1) The `import foo` syntax will *only* search sys.path.  If `foo`
   isn't in sys.path, it won't be found.  Period.  Without absolute
   imports, the import system will also search the same directory
   that the importing file resides in, so that you can easily
   import from the same folder.

2) From inside a package, you can use a dot syntax to refer to higher
   levels of the current package.  For example, if you are in the
   package lldbsuite.test.utility, then ..foo refers to
   lldbsuite.test.foo.  You can use this notation with the
   `from X import Y` syntax to write intra-package references.  For
   example, using the previous locationa s a starting point, writing
   `from ..support import seven` would import lldbsuite.support.seven

Since this is now the default behavior in Python 3, this means that
importing from the same directory with `import foo` *no longer works*.
As a result, the only way to have portable code is to force absolute
imports for all versions of Python.

See PEP 0328 [https://www.python.org/dev/peps/pep-0328/] for more
information about absolute and relative imports.

Zachary Turner 19474e1801 Remove `use_lldb_suite` from the package, and don't import it anymore.
This module was originally intended to be imported by top-level
scripts to be able to find the LLDB packages and third party
libraries.  Packages themselves shouldn't need to import it,
because by the time it gets into the package, the top-level
script should have already done this.  Indeed, it was just
adding the same values to sys.path multiple times, so this
patch is essentially no functional change.

To make sure it doesn't get re-introduced, we also delete the
`use_lldb_suite` module from `lldbsuite/test`, although the
original copy still remains in `lldb/test`

Zachary Turner 7d564544eb Make dosep correctly invoke the top-level script when forking out
packages/Python/lldbsuite is now a Python package, and it relies
on its __init__.py being called to do package-level initialization.
If you exec packages/Python/lldbsuite/dotest.py directly, you won't
get this package level initialization, and things will fail.  But
without this patch, this is exactly what dosep itself does.  To
launch the multi-processing fork, it was hardcoding a path to
dotest.py and exec'ing it from inside the package.

The fix here is to get the path of the top-level script, and
then exec'ing that instead.  A more robust solution would involve
refactoring the code so that dosep execs some internal script that
imports lldbsuite, but that's a bit more involved.
