Jason Molenda e32cd191f0 Correctly add the QueueID to a pending block's extended thread backtrace thread.
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.

Jason Molenda 37e9b5ab38 libBacktraceRecording __introspection_dispatch_queue_get_pending_items is
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.

Jason Molenda d84f606deb Small fix for i386 extended backtraces; wasn't skipping a
4-byte reserved area when reading the libBacktraceRecording API results.
Also, add a little logging about queues being created.

Jason Molenda 2a6c252df2 Add some additional logging to the Mac OS X SystemRuntime. Fix a bug where lldb could free an inferior's vm_page.

Jason Molenda da276f9013 Adjust the calls to __introspection_dispatch_thread_get_item_info to
use a system-wide unique thread ID instead of a pthread_t to identify
the thread we want debug info for.  Also, free some more memory regions
that needed to be freed.

Jason Molenda 2fd83355a8 Change the Mac OS X SystemRuntime plugin from using the placeholder
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.

Jason Molenda 5e8dce4dbf Add new Queue, QueueItem, Queuelist, SBQueue, SBQueueItem classes to represent
libdispatch aka Grand Central Dispatch (GCD) queues.  Still fleshing out the
documentation and testing of these but the overall API is settling down so it's
a good time to check it in.

Jason Molenda a6e9130d52 Add logging for the SB API which creates extended
threads.

Take a stab at fixing the too-soon freeing of the extended
backtrace thread list in Process.

Jason Molenda 8ee9cb5891 Add a new SBThread::GetExtendedBacktraceOriginatingIndexID() method
(and same thing to Thread base class) which can be used when looking
at an ExtendedBacktrace thread; it will try to find the IndexID() of
the original thread that was executing this backtrace when it was
recorded.  If lldb can't find a record of that thread, it will return
the same value as IndexID() for the ExtendedBacktrace thread.

Jason Molenda a7b5afa91b Commit a work-in-progress system runtime for Mac OS X which won't
do anything right now.  Add a few new methods to the Thread base
class which HistoryThread needs.  I think I updated all the 
CMakeLists files correctly for the new plugin.
