Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes:
- Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file". 
- modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly
- Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was.
- modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile()

Cleaned up header includes a bit as well.

- Tweaked a parameter name in SBDebugger.h so my typemap will catch it;
- Added a SBDebugger.Create(bool, callback, baton) to the swig interface;
- Added SBDebugger.SetLoggingCallback to the swig interface;
- Added a callback utility function for log callbacks;
- Guard against Py_None on both callback utility functions;

- Added a FIXME to the SBDebugger API test;
- Added a __del__() stub for SBDebugger.

We need to be able to get both the log callback and baton from an
SBDebugger if we want to protect against memory leaks (or make the user
responsible for holding another reference to the callback).
Additionally, it's impossible to revert from a callback-backed log
mechanism to a file-backed log mechanism.

Previously we put a WatchpointSentry object within StopInfo.cpp to disable-and-then-enable the watchpoint itself
while we are performing the actions associated with the triggered watchpoint, which can cause the user-initiated
watchpoint disabling action to be negated.

Add a test case to verify that a watchpoint can be disabled during the callbacks.

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).

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.
