for customizing "step-in" behavior (e.g. step-in doesn't step into code with no debug info), but also
the behavior of step-in/step-out and step-over when they step out of the frame they started in.
I also added as a proof of concept of this reworking a mode for stepping where stepping out of a frame
into a frame with no debug information will continue stepping out till it arrives at a frame that does
have debug information. This is useful when you are debugging callback based code where the callbacks
are separated from the code that initiated them by some library glue you don't care about, among other
things.

This header is generally not available on mingw and can cause build errors.
The windows host code does provide timespec definition that can be used for
mingw case.

Seed the QueueItem objects with the item_refs and addresses when they are fetched
in one batch. If additional information is needed from the QueueItem, fetch it
lazily one pending item per function call.

changing the data it returns; this change accepts either the old format or
the new format. It doesn't yet benefit from the new format's additions -
but I need to get this checked in so we aren't rev-locked.
Also add a missing .i entry for SBQueue::GetNumRunningItems() missing from
the last checkin.

items; the backing Queue object has the number of pending items
already cached. Also, add SBQueue::GetNumRunningItems() to provide
that information.

Please do not add header files that are required in public APIs without first checking with us. This broke the LLDB builds at Apple because the lldb-dll-export.h wasn't included in the LLDB.framework and it was being included by public API header files.

hold a strong pointer to that extended backtrace thread in the Process
just like we do for asking a thread's extended backtrace.
Also, give extended backtrace threads an invalid ThreadIndexID number.
We'll still give them valid thread_id's. Clients who want to know the
original thread's IndexID can call GetExtendedBacktraceOriginatingIndexID().

consult the ValueObject's error and report that if
there's some problem.

I carefully reviewed exactly how the IOHandlers interact and found places where we weren't properly controlling things. There should be no overlapping prompts and all output should now come out in a controlled fashion.

Also remove SetStopOthers from the ThreadPlanCallFunction, because if the value you have doesn't match what is
in the EvaluateExpressionOptions the plan was passed when created it won't work correctly.

The way in which we were determining whether a python module had already been imported in the current session stopped working due to the IOHandler changes
As a result, importing in a new debug session a module which had been imported in a previous session did not work
This commit restores that functionality by checking for the module's presence in the session dictionary (which should be more correct anyway)

Fix a bug where calling SBFrame::FindValue() would cause a copy of all variables in the block to be inserted in the frame's variable list, regardless of whether those same variables were there or not - which means one could end up with a frame with lots of duplicate copies of the same variables

specify a list of functions which should be treated as trap handlers.
This will be primarily useful to people working in non-user-level
process debugging - kernels and other standalone environments.
For most people, the trap handler functions provided by the Platform
plugin will be sufficient.

add a new pure virtual CalculateTrapHandlerSymbolNames() that Platform
subclasses must implement which fills in the function name list with any
trap handlers that are expected on that platform.

aka asynchronous signal handlers, which subclasses should fill
in as appropriate. For most Unix user process environments,
the one entry in this list is _sigtramp. For bare-board and
kernel environments, there will be different sets of trap
handlers.
The unwinder needs to know when a frame is a trap handler
because the rules it enforces for the frame "above" the
trap handler is different from most middle-of-the-stack frames.

ObjectFile::SetLoadAddress (Target &target,
lldb::addr_t value,
bool value_is_offset);
Now "value" is a slide if "value_is_offset" is true, and "value" is an image base address otherwise. All previous usage of this API was using slides.
Updated the ObjectFileELF and ObjectFileMachO SetLoadAddress methods to do the right thing.
Also updated the ObjectFileMachO::SetLoadAddress() function to not load __LINKEDIT when it isn't needed and to only load sections that belong to the executable object file.

Move some code that was in DynamicLoaderPOSIXDLYD into the
base class DynamicLoader. In the case of UpdateLoadedSections(),
the test to see whether a file is loadable (its address is zero)
is not generally applicable so that test is changed to a more
universally applicable check for the SHF_ALLOC flag on the section.
Also make it explicit that the reading of the module_id in
DynamicLoaderPOSIXDYLD::GetThreadLocalData() is using a hardcoded
size (of module_id) of 4, which might not be appropriate on
big-endian 64-bit systems, leaving a FIXME comment in place.

libldi library to collect extended backtrace information; switch
to the libBacktraceRecording library and its APIs. Complete the
work of adding QueueItems to Queues and allow for the QueueItems
to be interrogated about their extended backtraces in turn.
There's still cleanup and documentation to do on this code but the
code is functional and I it's a good time to get the work-in-progress
checked in.

The many many benefits include:
1 - Input/Output/Error streams are now handled as real streams not a push style input
2 - auto completion in python embedded interpreter
3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use
4 - it is now possible to use curses to drive LLDB (please try the "gui" command)
We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases.

GDBRemoteCommunicationServer::LaunchProcess () now uses the built-up
ProcessLaunchArgs rather than clearing and setting items from the
function arguments. I added setters for the arguments and launch
flags, which lldb-gdbserver uses for its specification of the
commandline-specified startup app (if one is specified).
LaunchProcess () also adds a new reaper monitor that it applies to
the launched process if no process monitor has already been applied.
This addresses an issue where the 'k' command would generate (possibly
false) warnings about not being able to positively state whether a
killed process actually terminated. GDBRemoteCommunicationServer now
definitely knows the disposition of its children.
