Reimplemented the code that backed the "settings" in lldb. There were many issues with the previous implementation:
- no setting auto completion
- very manual and error prone way of getting/setting variables
- tons of code duplication
- useless instance names for processes, threads

Now settings can easily be defined like option values. The new settings makes use of the "OptionValue" classes so we can re-use the option value code that we use to set settings in command options. No more instances, just "does the right thing".

Now it's possible to use SBInputReader callbacks in Python.

We leak the callback object, unfortunately. A __del__ method can be added
to SBInputReader, but we have no way to check the callback function that
is on the reader. So we can't call Py_DECREF on it when we have our
PythonCallback function. One way to do it is to assume that reified
SBInputReaders always have a Python callback (and always call Py_DECREF).
Another one is to add methods or properties to SBInputReader (or make the
m_callback_function property public).

Remove the process->DisableWatchpoint() and EnableWatchpoint() calls since the sentry object is already doing that.

Watchpoint conditions were hitting watchpoint, smashing LLDB's stack.
Make sure watchpoint is properly disabled and subsequently enabled while performing watchpoint actions.

SBValue::GetTypeName and SBValue::GetByteSize might have to update the dynamic value - which might involve running code.  So they need to take the stop lock & target locks.

when you want to find the caller's saved pc, you look up the return address
register and use that.  On arm, for instance, this would be the contents of
the link register (lr).

If the eh_frame CIE defines an RA, record that fact in the UnwindPlan.

When we're finding a saved register, if it's the pc, lok for the location
of the return address register instead.

Furthermore, use two additional slots under the script interpreter to store the PseudoTerminal and
the InputReaderSP pertaining to the embedded python interpreter -- resulted from the
ScriptInterpreterPython::ExecuteInterpreterLoop() call -- to facilitate separation from what is being
used by the PythonInputReaderManager instances.

When trying to take snapshots of a watched variable, if the frame is unable to evaluate the variable expression,
do not take the sanpshot and forget about the stop info.  It is possible that the variable expression has gone
out of scope, we'll revise the hit count due to the false alarms.

Added a new "objc_refs" command that will track down all allocations on the heap that have the "isa" for the objective C class at offset zero. This will need to be improved to deal with KVO classes, but it is a start. It also disallows looking up a pointer value of zero since that would return way too many matches.
