Summary:
print build errors nicely in test output
This test infrastructure change adds a new Python exception
for test subject builds that fail. The output of the build
command is captured and propagated to both the textual test
output display code and to the test event system.
The ResultsFormatter objects have been modified to do something
more useful with this information. The xUnit formatter
now replaces the non-informative Python build error stacktrace
with the build error content. The curses ResultsFormatter
prints a 'B' for build errors rather than 'E'.
The xUnit output, in particular, makes it much easier for
developers to track down test subject build errors that cause
test failures when reports come in from CI.

Summary:
This change enhances the LLDB test infrastructure to convert
load-time exceptions in a given Python test module into errors.
Before this change, specifying a non-existent test decorator,
or otherwise having some load-time error in a python test module,
would not get flagged as an error.
With this change, typos and other load-time errors in a python
test file get converted to errors and reported by the
test runner.
This change also includes test infrastructure tests that include
covering the new work here. I'm going to wait until we have
these infrastructure tests runnable on the main platforms before
I try to work that into all the normal testing workflows.
The test infrastructure tests can be run by using the standard python module testing practice of doing the following:
cd packages/Python/lldbsuite/test_event
python -m unittest discover -s test/src -p 'Test*.py'
Those tests run the dotest inferior with a known broken test and verify that the errors are caught. These tests did not pass until I modified dotest.py to capture them properly.
@zturner, if you have the chance, if you could try those steps above (the python -m unittest ... line) on Windows, that would be great if we can address any python2/3/Windows bits there. I don't think there's anything fancy, but I didn't want to hook it into test flow until I know it works there.
I'll be slowly adding more tests that cover some of the other breakage I've occasionally seen that didn't get collected as part of the summarization. This is the biggest one I'm aware of.

Python 3.5 is pickier about the distinction between chars and bytes (and strings and bytearrays) than Python 2.7.

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.
