that don't actually call 'print()'
Summary:
A lot of tests do this trick but the vast majority of them don't even call `print()`.
Most of this patch was generated by a script that just looks at all the files and deletes the line if there is no `print (` or `print(` anywhere else in the file.
I checked the remaining tests manually and deleted the import if we never call print (but instead do stuff like `expr print(...)` and similar false-positives).
I also corrected the additional empty lines after the import in the files that I manually edited.

Implement major improvements to multithreaded program support. Notably,
support tracking new and exited threads, associate signals and events
with correct threads and support controlling individual threads when
resuming.
Firstly, use PT_SET_EVENT_MASK to enable reporting of created and exited
threads via SIGTRAP. Handle TRAP_LWP events to keep track
of the currently running threads.
Secondly, update the signal (both generic and SIGTRAP) handling code
to account for per-thread signals correctly. Signals delivered
to the whole process are reported on all threads, while per-thread
signals and events are reported only to the specific thread.
The remaining threads are marked as 'stopped with no reason'. Note that
NetBSD always stops all threads on debugger events.
Thirdly, implement the ability to set every thread as running, stopped
or single-stepping separately while continuing the process. This also
provides the ability to send a signal to the whole process or to one
of its thread while resuming.

Summary:
Instead of each test case knowing its depth relative to the test root,
we can just have dotest add the folder containing Makefile.rules to the
include path.
This was motivated by r370616, though I have been wanting to do this
ever since we moved to building tests out-of-tree.
The only manually modified files in this patch are lldbinline.py and
plugins/builder_base.py. The rest of the patch has been produced by this
shell command:
find . \( -name Makefile -o -name '*.mk' \) -exec sed --in-place -e '/LEVEL *:\?=/d' -e '1,2{/^$/d}' -e 's,\$(LEVEL)/,,' {} +

Add a convenience 'expectedFailureNetBSD' decorator and mark all tests
currently failing on NetBSD with it. Also skip a few tests that hang
the test suite. This should establish a baseline for the test suite
and get us closer to enabling tests on buildbot. This will help us
catch regressions while we still have a lot of work to do to get tests
working.
It seems that there are also some flaky tests. I am going to address
them later on.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Skip a number of tests on Windows that are flakey and will pass/fail unexpectedly every dozen or so runs.

This is a set of tests that were all marked as failing becuse of several different bugs. A couple of the bugs are now resolved as fixed since all the tests that were failing associated with the bug are now passing. It is possible that some of them are false positives, but there's a large number of unexpectedly passing tests on Windows, so I am doing a bulk un-xfail to get the buildbot to green.

Summary:
1) Several tests that are flakey on windows fail the run even if they are marked as expected to be flakey. This is because they fail frequently enough that even a retry won't help
2) Skip several tests on Windows that will occasionally hang rather than failing or exiting. This is causing the entire test suite to hang

pseudo_barrier_wait() begins by decrementing an atomic variable. Since
these are always_inline in libc++, there is no line table anchor to
break on before we decrement it. This meant that on gcc we stopped after
the variable has been decremented, which meant that thread2 could have
exited, violating the test setup. On clang this wasn't a problem
because it generated some line table entries for the do{}while(0) loop
in the macro, so we still ended up stopping, before we touched the
variable.
I fix this by adding a dummy statement before the pseudo_barrier_wait()
command and setting the breakpoint there.

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.

*** 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:
TestExitDuringStep was very rarely hanging on the buildbots. I can't be sure, but I believe this
was because of the fact that it declared its pseudo_barrier variable as "volatile int", which is
not sufficient to guarantee corectness (also, all other tests used atomic variables for this, and
they were passing reliably AFAIK). Besides switching to an atomic variable in this test as well,
I have also took this opportunity to unify all the copies of the pseudo_barrier code to a single
place to reduce the chance of this happening again.

The Windows 10 loader spawns threads at startup, so
tests which count threads or assume that a given user
thread will be at a specific index are incorrect in
this case. The fix here is to use the standard mechanisms
for getting the stopped thread (which is all we are
really interested in anyway) and correlating them with
the breakpoints that were set, and doing checks against
those things.
This fixes about 6 tests on Windows 10.

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`

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.

This is the conclusion of an effort to get LLDB's Python code
structured into a bona-fide Python package. This has a number
of benefits, but most notably the ability to more easily share
Python code between different but related pieces of LLDB's Python
infrastructure (for example, `scripts` can now share code with
`test`).
