Added a new API call to help efficiently determine if a SBValue could have children:

     bool
     SBValue::MightHaveChildren ();
     
This is inteneded to be used bui GUI programs that need to show if a SBValue needs a disclosure triangle when displaying a hierarchical type in a tree view without having to complete the type (by calling SBValue::GetNumChildren()) as completing the type is expensive.

Enrico Granata e3e91517ff <rdar://problem/12437442>
Given our implementation of ValueObjects we could have a scenario where a ValueObject has a dynamic type of Foo* at one point, and then its dynamic type changes to Bar*
If Bar* has synthetic children enabled, by the time we figure that out, our public API is already vending SBValues wrapping a DynamicVO, instead of a SyntheticVO and there was
no trivial way for us to change the SP inside an SBValue on the fly
This checkin reimplements SBValue in terms of a wrapper, ValueImpl, that allows this substitutions on-the-fly by overriding GetSP() to do The Right Thing (TM)
As an additional bonus, GetNonSyntheticValue() now works, and we can get rid of the ForceDisableSyntheticChildren idiom in ScriptInterpreterPython
Lastly, this checkin makes sure the synthetic VOs get the correct m_value and m_data from their parents (prevented summaries from working in some cases)

SBProcess::SetSelectedThreadByID() had a "uint32_t tid" parameter which would truncate 64 bit thread IDs (lldb::tid_t is 64 bit).

Jim Ingham 4f465cff8a Change the Thread constructor over to take a Process& rather than a ProcessSP. We can't create Threads with a NULL ProcessSP, so it makes no sense to use the SP.
Then make the Thread a Broadcaster, and get it to broadcast when the selected frame is changed (but only from the Command Line) and when Thread::ReturnFromFrame 
changes the stack.
Made the Driver use this notification to print the new thread status rather than doing it in the command.
Fixed a few places where people were setting their broadcaster class by hand rather than using the static broadcaster class call.

Enrico Granata 21dfcd9d41 Implementing plugins that provide commands.
This checkin adds the capability for LLDB to load plugins from external dylibs that can provide new commands
It exports an SBCommand class from the public API layer, and a new SBCommandPluginInterface

There is a minimal load-only plugin manager built into the debugger, which can be accessed via Debugger::LoadPlugin.

Plugins are loaded from two locations at debugger startup (LLDB.framework/Resources/PlugIns and ~/Library/Application Support/LLDB/PlugIns) and more can be (re)loaded via the "plugin load" command

For an example of how to make a plugin, refer to the fooplugin.cpp file in examples/plugins/commands

Caveats:
	Currently, the new API objects and features are not exposed via Python.
	The new commands can only be "parsed" (i.e. not raw) and get their command line via a char** parameter (we do not expose our internal Args object)
	There is no unloading feature, which can potentially lead to leaks if you overwrite the commands by reloading the same or different plugins
	There is no API exposed for option parsing, which means you may need to use getopt or roll-your-own

Filipe Cabecinhas c5041918dd Added SBDebugger's log callbacks to Python-land
- 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.

Added new API to lldb::SBTypeMember for bitfields:

    bool SBTypeMember::IsBitfield();
    uint32_t SBTypeMember::GetBitfieldSizeInBits();

Also added new properties for easy access. Now SBTypeMember objects in python have a "fields" property for all type fields, "bases" for all direct bases, "vbases" for all virtual base classes and "members" for a combo of all three organized by bit offset. They all return a python list() of SBTypeMember objects. Usage:
(lldb) script
>>> t = lldb.target.FindFirstType("my_type")
>>> for field in t.fields:
...     print field
>>> for vbase in t.vbases:
...     print vbase
>>> for base in t.bases:
...     print base
>>> for member in t.members:
...     print member

Also added new "is_bitfield" property to the SBTypeMember objects that will return the result of SBTypeMember::IsBitfield(), and "bitfield_bit_size" which will return the result of SBTypeMember::GetBitfieldSizeInBits();

I also fixed "SBTypeMember::GetOffsetInBytes()" to return the correct byte offset.

Jim Ingham cfc0935ed9 Added an lldb_private & equivalent SB API to send an AsyncInterrupt to the event loop.
Convert from calling Halt in the lldb Driver.cpp's input reader's sigint handler to sending this AsyncInterrupt so it can be handled in the 
event loop.
If you are attaching and get an async interrupt, abort the attach attempt.
Also remember to destroy the process if get interrupted while attaching.
Getting this to work also required handing the eBroadcastBitInterrupt in a few more places in Process WaitForEvent & friends.

Greg Clayton 5ef31a9c46 Added documentation for many of our python properties and also made the property help show up by declaring the properties correctly. We previosly declared properties into a local "x" variable, what I didn't realize is that the help will use this as the property name for the help output.
