while we develop a better understanding of how to manage the thread lists in a platform-independant fashion.

lldb_private::Thread subclasses were changed and the API was not respected properly.
This checkin aims to fix this. The process now has two thread lists: a real thread list for threads that are created by the lldb_private::Process subclass, and the user visible threads. The user visible threads are the same as the real threas when no OS plug-in in used. But when an OS plug-in is used, the user thread can be a combination of real and "memory" threads. Real threads can be placed inside of memory threads so that a thread appears to be different, but is still controlled by the actual real thread. When the thread list needs updating, the lldb_private::Process class will call the: lldb_private::Process::UpdateThreadList() function with the old real thread list, and the function is expected to fill in the new real thread list with the current state of the process. After this function, the process will check if there is an OS plug-in being used, and if so, it will give the old user thread list, the new real thread list and the OS plug-in will create the new user thread list from both of these lists. If there is no OS plug-in, the real thread list is the user thread list.
These changes keep the lldb_private::Process subclasses clean and no changes are required.

the macros and just use C++11.

C++11 is being used. To do this, we follow what we have done for shared pointers and we define a STD_UNIQUE_PTR macro that can be used and it will "do the right thing". Due to some API differences in std::unique_ptr and due to the fact that we need to be able to compile without C++11, we can't use move semantics so some code needed to change so that it can compile with either C++.
Anyone wanting to use a unique_ptr or auto_ptr should now use the "STD_UNIQUE_PTR(TYPE)" macro.

Made some fixes to the OperatingSystemPython class:
- If any thread dictionary contains any "core=N" key/value pairs then the threads obtained from the lldb_private::Process itself will be placed inside the ThreadMemory threads and will be used to get the information for a thread.
- Cleaned up all the places where a thread inside a thread was causing problems

Added the ability for OS plug-ins to lazily populate the thread this. The python OS plug-in classes can now implement the following method:
class OperatingSystemPlugin:
def create_thread(self, tid, context):
# Return a dictionary for a new thread to create it on demand
This will add a new thread to the thread list if it doesn't already exist. The example code in lldb/examples/python/operating_system.py has been updated to show how this call us used.
Cleaned up the code in PythonDataObjects.cpp/h:
- renamed all classes that started with PythonData* to be Python*.
- renamed PythonArray to PythonList. Cleaned up the code to use inheritance where
- Centralized the code that does ref counting in the PythonObject class to a single function.
- Made the "bool PythonObject::Reset(PyObject *)" function be virtual so each subclass can correctly check to ensure a PyObject is of the right type before adopting the object.
- Cleaned up all APIs and added new constructors for the Python* classes to they can all construct form:
- PyObject *
- const PythonObject &
- const lldb::ScriptInterpreterObjectSP &
Cleaned up code in ScriptInterpreterPython:
- Made calling python functions safer by templatizing the production of value formats. Python specifies the value formats based on built in C types (long, long long, etc), and code often uses typedefs for uint32_t, uint64_t, etc when passing arguments down to python. We will now always produce correct value formats as the templatized code will "do the right thing" all the time.
- Fixed issues with the ScriptInterpreterPython::Locker where entering the session and leaving the session had a bunch of issues that could cause the "lldb" module globals lldb.debugger, lldb.target, lldb.process, lldb.thread, and lldb.frame to not be initialized.

Added a new setting that allows a python OS plug-in to detect threads and provide registers for memory threads. To enable this you set the setting:
settings set target.process.python-os-plugin-path lldb/examples/python/operating_system.py
Then run your program and see the extra threads.
