Jim Ingham 862d1bbdf6 When stepping, handle the case where the step leaves us with
the same parent frame, but different current frame - e.g. when
you step past a tail call exit from a function.  Apply the same
"avoid-no-debug" rules to this case as for a "step-in".

Jim Ingham 4b4b2478fc This commit reworks how the thread plan's ShouldStopHere mechanism works, so that it is useful not only
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.

Jim Ingham 4d56e9c1cb This commit does two things. One, it converts the return value of the QueueThreadPlanXXX
plan providers from a "ThreadPlan *" to a "lldb::ThreadPlanSP".  That was needed to fix
a bug where the ThreadPlanStepInRange wasn't checking with its sub-plans to make sure they
succeed before trying to proceed further.  If the sub-plan failed and as a result didn't make
any progress, you could end up retrying the same failing algorithm in an infinite loop.

LLDB is crashing when logging is enabled from lldb-perf-clang. This has to do with the global destructor chain as the process and its threads are being torn down.

All logging channels now make one and only one instance that is kept in a global pointer which is never freed. This guarantees that logging can correctly continue as the process tears itself down.

Daniel Malea d01b2953fa Resolve printf formatting warnings on Linux:
- use macros from inttypes.h for format strings instead of OS-specific types

Jim Ingham 25f6670003 Make the ThreadPlanStepThrough set a backstop breakpoint on the return address from
the function it is being asked to step through, so that even if we get the trampoline
target wrong (for instance) we will still not lose control.

The other fix here is to tighten up the handling of the case where the current plan
doesn't explain the stop, but a plan above us does.  In that case, if the plan that
does explain the stop says it is done, we need to clean up the plans below it and 
continue on with our processing.
