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".

'add-dsym' (aka 'target symbols add') should display error messages when dsym file is not found
or the dsym uuid does not match any existing modules. Add TestAddDsymCommand.py test file.

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.

I also added a typemap to make DispatchInput usable in Python.

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.

tread on the m_embedded_thread_input_reader_sp singleton maintained by the script interpreter.
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.

Add an lldb command line option to specify a core file: --core/-c.
For consistency, change the "target create" command to also use --core.

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.

Remember to copy the address byte size and the byte order when copying data into a DWARF location object, or things will go wrong.

Added back member initialization for m_batch_command_mode, which was most likely removed accidentally a while back.
The consequence occurred recently probably due to our swicth to build with c++11.

the expression returns nothing.  There is now a
setting, "notify-void."  When the user enables
that setting, lldb prints (void) if an expression's
result is void.  Otherwise, lldb is silent.
