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.

4fbd67ac11 Add a new option to Platform::LoadImage to install the image
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".

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.

cb8ea4bd23 Make TestThreadStates more stable
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.

3e9e7d2822 Make TestThreadSpecificBreakpoint.py more focused.
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.

296e063d8f PTRACE ABI to read FXSAVE area for 32-bit inferior
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

df55f522bd Fix race during process interruption
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.

48ef8d4c37 Fix some issues with swig & string conversion.
This patch fixes two issues:

1) Popen needs to be used with universal_newlines=True by default.
   This elicits automatic decoding from bytes -> string in Py3,
   and has no negative effects in other Py versions.
2) The swig typemaps for converting between string and (char*, int)
   did not work correctly when the length of the string was 0,
   indicating an error.  In this case we would try to construct a
   string from uninitialized data.
3) Ironically, the bug mentioned in #2 led to a test passing on
   Windows that was actually broken, because the test was written
   such that the assertion was never even getting checked, so it
   passed by default.  So we additionally fix this test to also
   fail if the method errors.  By fixing this test it's now broken
   on Windows, so we also xfail it.

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

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`
