TestConcurrentEvents was marked with a XFAIL decorator at class level, which actually does not
work, and causes the class to be silently skipped everywhere. It seems that making it work at
class level is quite a difficult task, so I will just move it to the individual test methods. I
will follow this up with a commit which makes the decorator blow up in case someone tries to
apply it to a class in the future.

There were a number of problems preventing this from working:
1. The SWIG typemaps for converting Python lists to and from C++
arrays were not updated for Python 3. So they were doing things
like PyString_Check instead of using the PythonString from
PythonDataObjects.
2. ProcessLauncherWindows was ignoring the environment completely.
So any test that involved launching an inferior with any kind
of environment variable would have failed.
3. The test itself was using process.GetSTDOUT(), which isn't
implemented on Windows. So this was changed to save the
value of the environment variable in a local variable and
have the debugger look at the value of the variable.

The system can create threads for a system threadpool, so there is
no guarantee that the thread that is stopped is thread 1. So use
a more robust check.

Summary:
The testcase TestNoreturnUnwind.py was failing
because the unwind from the vdso library was not
successful for clang compiler while it was passing
for gcc. It was passing for gcc since the unwind plan
used was the assembly plan and the ebp register was
set by the main function in case of gcc and was not
used by the functions in the call flow to the vdso, whereas
clang did not emit assembly prologue for main and so
the assembly unwind was failing. Normally in case of
failure of assembly unwind, lldb switches to EH CFI frame
based unwinding, but this was not happening for
the first frame. This patch tries to fix this behaviour by
falling to EH CFI frame based unwinding in case of assembly
unwind failure even for the first frame.
The test is still marked as XFAIL since it relys on the fix
of another bug.

On linux we need the process to give us special permissions before we can attach to it.
Previously, the code for this was copied into every file that needed it. This moves the code to a

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.

LLDB don't detect the loading of a shared object file linked against the
main executable before the static initializers are executed for the
given module. Because of this it is not possible to get breakpoint hits
in these static initializers and to display proper debug info in case of
a crash in these codes.

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.

This change introduce 3 different working mode for Platform::LoadImage
depending on the file specs specified.
* If only a remote file is specified then the remote file is loaded on
the target (same behavior as before)
* If only a local file is specified then the local file is installed to
the current working directory and then loaded from there.
* If both local and remote file is specified then the local file is
installed to the specified location and then loaded from there.
The same options are exposed on the SB API with a new method LoadImage
method while the old signature presers its meaning.
On the command line the installation of the shared library can be specified
with the "--install" option of "process load".

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.

This is a resubmit of r254403, see that commit's message for context. This fixes an issue in the
original commit, where we would incorrectly interrupt the process if the interrupt request came
just as we were about to send the stopped event to the public.

Summary:
Because of the large number of XFAILs TestThreadStates has decayed quite a bit. This commit does
the following:
- removes the "breakpoint list" expectations. Most tests have been failing on this, because the
command output changed quite a while back. I remove it, because run_break_set_by_file_and_line
already does a decent amount of checking
- fixup test_state_after_expression: this was calling the wrong function by mistake. As now the
function actually tests something (which we know is broken), I needed to XFAIL it as well.
- replaces the sleep() with a proper wait-for-event functionality in parts which use async mode,
to stabilize the one function that actually tests something.

This test would fail before if conditional breakpoints weren't
working correctly, and the nature of the test (spinning up 10
threads, etc) opens the door to raciness.
This patch vastly simplifies the test, removes the need for relying
on conditional expression evaluation, and as a result makes the
correctness of the test vastly easier to reason about and reduces
flakiness.

The fix won't work for local Windows tests but dlopen don't available

Summary:
- Problem occurs when:
-- 32-bit inferiors run on x86_32 machine and
the architecture doesn't have AVX feature
-- This causes FPRType to be set to eFPRTypeFXSAVE
-- PTRACE_GETFPREGS was being used to read FXSAVE area
-- For 32-bit inferiors running on x86_32 machine,
PTRACE_GETFPREGS reads FSAVE area and not FXSAVE area
- Changed ptrace API to PTRACE_GETREGSET for 32-bit inferiors
-- This reads FPR data in FXSAVE format.
-- For 64-bit inferiors, no change has been made.
- Modified XFAIL for TestReturnValue.py
-- Earlier, this test was passing for Linux OS
-- Now, it passes for Android OS as well

Summary:
The following situation was occuring in TestAttachResume:
- we did a "continue" from a breakpoint (which involves a private start-stop to step over the
breakpoint)
- after receiving the stop-reply from the step-over, we issue a "detach" (which requires a
process interrupt)
- at this moment, the public state is "running", private state is "about-to-be-stopped" (the
stopped event was broadcast, but it was not received yet)
- StopForDestroyOrDetach (public thread) notes the public state is running, sends an interrupt
request to the private thread
- private thread gets the eBroadcastBitInterrupt (before the eStateStopped message), and asks the
process plugin to stop (via Halt())
- process plugin says it has nothing to do as the process is already stopped
- private thread shrugs and carries on. receives the stop event, restores the breakpoint and
resumes the process.
- after a while, the public thread times out and says it failed to stop the process
This patch does the following:
- splits Halt() into two functions, private and public, their usage depends on the context
- public Halt(): sends eBroadcastBitInterrupt to the private thread and waits for the Stop
event
- HaltPrivate(): asks the plugin to stop and makes a note that the halt was requested. When the
next stop event comes it sets the interrupt flag on it.
- removes HijackPrivateProcessEvents(), as the only user (old Halt()) has gone away
- removes the m_currently_handling_event hack, as the new Halt() does not need it
- adds a use_run_lock parameter to public Halt() and WaitForProcessToStop(). This was needed
because RunThreadPlan uses Halt() while holding the run lock and we don't want Halt() to take
it away from him.
