The way in which we were determining whether a python module had already been imported in the current session stopped working due to the IOHandler changes
As a result, importing in a new debug session a module which had been imported in a previous session did not work
This commit restores that functionality by checking for the module's presence in the session dictionary (which should be more correct anyway)

The many many benefits include:
1 - Input/Output/Error streams are now handled as real streams not a push style input
2 - auto completion in python embedded interpreter
3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use
4 - it is now possible to use curses to drive LLDB (please try the "gui" command)
We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases.

lldb_private::Debugger was #including some "lldb/API" header files which causes tools (lldb-platform and lldb-gdbserver) that link against the internals only (no API layer) to fail to link depending on which calls were being used.
Also fixed the current working directory so that it gets set correctly for remote test suite runs. Now the remote working directory is set to: "ARCH/TESTNUM/..." where ARCH is the current architecture name and "TESTNUM" is the current test number.
Fixed the "lldb-platform" and "lldb-gdbserver" to not warn about mismatched visibility settings by having each have their own exports file which contains nothing. This forces all symbols to not be exported, and also quiets the linker warnings.

the installed SDK to using the current OS installed headers/libraries.
This change is to address the removal of the Python framework
from the Mac OS X 10.9 (Mavericks) SDK, and is the recommended
workaround via https://developer.apple.com/library/mac/technotes/tn2328/_index.html

- Made the dynamic register context for the GDB remote plug-in inherit from the generic DynamicRegisterInfo to avoid code duplication
- Finished up the target definition python setting stuff.
- Added a new "slice" key/value pair that can specify that a register is part of another register:
{ 'name':'eax', 'set':0, 'bitsize':32, 'encoding':eEncodingUint, 'format':eFormatHex, 'slice': 'rax[31:0]' },
- Added a new "composite" key/value pair that can specify that a register is made up of two or more registers:
{ 'name':'d0', 'set':0, 'bitsize':64 , 'encoding':eEncodingIEEE754, 'format':eFormatFloat, 'composite': ['s1', 's0'] },
- Added a new "invalidate-regs" key/value pair for when a register is modified, it can invalidate other registers:
{ 'name':'cpsr', 'set':0, 'bitsize':32 , 'encoding':eEncodingUint, 'format':eFormatHex, 'invalidate-regs': ['r8', 'r9', 'r10', 'r11', 'r12', 'r13', 'r14', 'r15']},
This now completes the feature that allows a GDB remote target to completely describe itself.

Added logging for the OS plug-in python objects in OperatingSystemPython so we can see the python dictionary returned from the plug-in when logging is enabled.

Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary.
So I defined a new "lldb::offset_t" which should be used for all file offsets.
After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed.
Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections.

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 code the initialize the register context in the OperatingSystemPython plug-in with the new PythonData classes, and added a test OperatingSystemPython module in lldb/examples/python/operating_system.py that we can use for testing.
