LLDB queries Spotlight to locate .dSYM bundles based on the UUID

This patch is the result of a discussion on lldb-dev, see
http://lists.llvm.org/pipermail/lldb-dev/2018-January/013111.html for
background.
For each test (should be eventually: each test configuration) a
separate build directory is created and we execute
make VPATH=$srcdir/path/to/test -C $builddir/path/to/test -f $srcdir/path/to/test/Makefile -I $srcdir/path/to/test
In order to make this work all LLDB tests need to be updated to find
the executable in the test build directory, since CWD still points at
the test's source directory, which is a requirement for unittest2.
Although we have done extensive testing, I'm expecting that this first
attempt will break a few bots. Please DO NOT HESITATE TO REVERT this
patch in order to get the bots green again. We will likely have to
iterate on this some more.

The commit breaks the case where you specify just a filename to the
compiler. Previously, it would look up the compiler in your path, now it
complains that the compiler is not found. One of the lldb buildbots is
depending on this. It seems like a nice feature to have, as it means
less typing and being able to avoid hard-coding the system compiler path
in the bot config.
This reverts commit r316393.

Summary:
This aims to replace the different decorators we've had on each libc++
test with a single solution. Each libc++ will be assigned to the
"libc++" category and a single central piece of code will decide whether
we are actually able to run libc++ test in the given configuration by
enabling or disabling the category (while giving the user the
opportunity to override this).
I started this effort because I wanted to get libc++ tests running on
android, and none of the existing decorators worked for this use case:
- skipIfGcc - incorrect, we can build libc++ executables on android
with gcc (in fact, after this, we can now do it on linux as well)
- lldbutil.skip_if_library_missing - this checks whether libc++.so is
loaded in the proces, which fails in case of a statically linked
libc++ (this makes copying executables to the remote target easier to
manage).
To make this work I needed to split out the pseudo_barrier code from the
force-included file, as libc++'s atomic does not play well with gcc on
linux, and this made every test fail, even though we need the code only
in the threading tests.
So far, I am only annotating one of the tests with this category. If
this does not break anything, I'll proceed to update the rest.

r298203 make SBPlatform::MakeDirectory less recursive, which breaks the
test suite creation of test directory hierarchy creation on the remote
target. Since the function was never fully recursive, and the name does
not imply recursiveness, I fix the problem by modifying the test runner
to do the recursion manually.
I also make the runner complain more loudly when it fails to create the
directory -- previously it just printed the error to stdout and caused
most of the tests to hang, which is not very helpful in diagnosing the
problem.

Summary:
This has been broken at least since the new test result framework was
added, which was over a year ago. It looks like nobody has missed it
since.
Removing this makes the gmodules handling code saner, as it already did
not know how to handle the multiple-compilers case.
My motivation for this is libc++ data formatters support on android -- I
am trying make a central way of determining whether libc++ tests can be
run, and without this, I would have to resort to similar hacks as the
gmodules code.

Summary:
The test suite calls realpath on the lldb executable then append "-mi" to it to find the path of the lldb-mi executable. This does not work when using CMake builds on *nix platforms. On *nix platforms when a version number is set on executables CMake generates the binary as ${name}-${version} with a symlink named ${name} pointing to it.
This results in the lldb executable being named lldb-4.0.0, and since lldb-4.0.0-mi doesn't ever match the lldb-mi executable these tests are always disabled.
This patch looks for lldb-mi in the same directory as lldb.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

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.

This moves all the global variables into a separate module called
`configuration`. This has a number of advantages:
1. Configuration data is centrally maintained so it's easy to get
a high level overview of what configuration data the test suite
makes use of.
2. The method of sharing configuration data among different parts
of the test suite becomes standardized. Previously we would
put some things into the `lldb` module, some things into the
`lldbtest_config` module, and some things would not get shared.
Now everything is shared through one module and is available to
the entire test suite.
3. It opens the door to moving some of the initialization code into
the `configuration` module, simplifying the implementation of
`dotest.py`.
There are a few stragglers that didn't get converted over to using
the `configuration` module in this patch, because it would have grown
the size of the patch unnecessarily. This includes everything
currently in the `lldbtest_config` module, as well as the
`lldb.remote_platform` variable. We can address these in the future.

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.

By default in Python 3, check_output() returns a program's output as
an encoded byte sequence. This means it returns a Py3 `bytes` object,
which cannot be compared to a string since it's a different fundamental
type.
Although it might not be correct from a purist standpoint, from a
practical one we can assume that all output is encoded in the default
locale, in which case using universal_newlines=True will decode it
according to the current locale. Anyway, universal_newlines also
has the nice behavior that it converts \r\n to \n on Windows platforms

This module was originally intended to be imported by top-level
scripts to be able to find the LLDB packages and third party

adding the same values to sys.path multiple times, so this

For convenience, we had added the folder that dotest.py was in
to sys.path, so that we could easily write things like
`import lldbutil` from anywhere and any test. This introduces
a subtle problem when using Python's package system, because when
unittest2 imports a particular test suite, the test suite is detached
from the package. Thus, writing "import lldbutil" from dotest imports
it as part of the package, and writing the same line from a test
does a fresh import since the importing module was not part of
the same package.
The real way to fix this is to use absolute imports everywhere. Instead
of writing "import lldbutil", we need to write "import
lldbsuite.test.util". This patch fixes up that and all other similar
cases, and additionally removes the script directory from sys.path
to ensure that this can't happen again.

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
