Ravitheja Addepally b2ba5a5467 Rewriting TestMultithreaded.py to solve flakyness on Linux
Summary:
test_listener_event_process_state checks for Threads
and Frames in the multithreaded_queue. The listener_func has
more computational load, which may be latter executed than the
pop leading to the failure. This patch tries to only check for
frames in listener_func as presence of frames also confirms 
prescence of threads and avoids the second push into the 
multithreaded_queue.

Jim Ingham 583bbb1dd4 Change over the broadcaster/listener process to hold shared or weak pointers
to each other.  This should remove some infrequent teardown crashes when the
listener is not the debugger's listener.

Processes now need to take a ListenerSP, not a Listener&.

This required changing over the Process plugin class constructors to take a ListenerSP, instead
of a Listener&.   Other than that there should be no functional change.

Zachary Turner 05021bb2ed Remove skip and xfail decorators for target architecture.
This removes the following decorators:

* skipIfI386
* expectedFailureI386
* expectedFailurex86_64
* skipIfArch
* skipUnlessArch
* skipUnlessI386

And other related decorators.  All code using those decorators
is updated to use expectedFailureAll and skipIf

Zachary Turner 4a289a93f7 Remove expectedFailureWindows decorator.
expectedFailureWindows is equivalent to using the general
expectedFailureAll decorator with oslist="windows".  Additionally,
by moving towards these common decorators we can solve the issue
of having to support decorators that can be called with or without
arguments.  Once all decorators are always called with arguments,
and this is enforced by design (because you can't specify the condition
you're decorating for without passing an argument) the implementation
of the decorators can become much simpler

Zachary Turner 7a5382de82 Move some of the common decorators to decorators.py.
This doesn't attempt to move every decorator.  The reason for
this is that it requires touching every single test file to import
decorators.py.  I would like to do this in a followup patch, but
in the interest of keeping the patches as bite-sized as possible,
I've only attempted to move the underlying common decorators first.
A few tests call these directly, so those tests are updated as part
of this patch.

Tamas Berghammer 0ecdae1bdc Merge ENABLE_THREADS and ENABLE_STD_THREADS markers
Both of these markers are used in the test suit for annotating when a
test needs multi threaded support. Previously they had slightly
different meening but they converged to the point where they are used
interchangably. This CL removes the ENABLE_STD_THREADS one to simplify
the test suite and avoid some confusion.

Zachary Turner d865c6b707 Remove the -c option from dotest.py.
This seems to be a legacy relic from days gone by where the
remote test suite runner operated completely differently than it
does today.  git blames and comments traced this functionality
back to about 2012, and nobody seems to know anything about it
now.

Zachary Turner 606e3a5221 Get rid of global variables in dotest.py
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.

Kamil Rytarowski 1f1a15332b getwd(3) with NULL pointer extension is supported on NetBSD
Summary:
The getwd() and getcwd() functions conform to IEEE Std 1003.1-1990
(POSIX.1).  The IEEE Std 1003.1-2004 (POSIX.1) revision marked
getwd() as legacy and recommended the use of getcwd() instead.  The IEEE
Std 1003.1-2008 (``POSIX.1'') revision removed getwd() from the
specification.

The ability to specify a NULL pointer and have getcwd() allocate memory
as necessary is an extension.

The getwd() function appeared in 4.0BSD.

Abhishek Aggarwal be994649b4 Fix to solve Bug 23139 & Bug 23560
Summary:
 - Reason of both bugs:

   1. For the very first frame, Unwinder doesn't check the validity
      of Full UnwindPlan before creating StackFrame from it:

        When 'process launch' command is run after setting a breakpoint
        in inferior, the Unwinder runs and saves only Frame 0 (the frame
        in which breakpoint was set) in thread's StackFrameList i.e.
        m_curr_frames_sp. However, it doesn't check the validity of the
        Full UnwindPlan for this frame by unwinding 2 more frames further.

   2. Unwinder doesn't update the CFA value of Cursor when Full UnwindPlan
      fails and FallBack UnwindPlan succeeds in providing valid CFA values
      for frames:

        Sometimes during unwinding of stack frames, the Full UnwindPlan
        inside the RegisterContextLLDB object may fail to provide valid
        CFA values for these frames. Then the Fallback UnwindPlan is used
        to unwind the frames.

        If the Fallback UnwindPlan succeeds, then it provides a valid new
        CFA value. The RegisterContextLLDB::m_cfa field of Cursor object
        is updated during the Fallback UnwindPlan execution. However,
        UnwindLLDB misses the implementation to update the 'cfa' field
        of this Cursor with this valid new CFA value.

 - This patch fixes both these issues.

 - Remove XFAIL in test files corresponding to these 2 Bugs

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 95c453a221 Tighten up sys.path, and use absolute imports everywhere.
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.

Zachary Turner c432c8f856 Move lldb/test to lldb/packages/Python/lldbsuite/test.
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`).
