There should be no functional changes as SBData creation functions already checked for NULL regardless of size - but it ensures consistency

This commit enables the new HasChildren() feature for synthetic children providers
Namely, it hooks up the required bits and pieces so that individual synthetic children providers can implement a new (optional) has_children call
Default implementations have been provided where necessary so that any existing providers continue to work and behave correctly
Next steps are:
2) writing smart implementations of has_children for our providers whenever possible
3) make a test case
llvm-svn: 166495
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.

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)

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.

I did a clean build and still got the problem so I'm backing this out until Enrico can
look at it.

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

This may (but shouldn't) break Linux (but I tested and it still worked on FreeBSD).
The same shell scripts are now used on Xcode and Makefiles, for generating
the SWIG bindings.
Some compatibility fixes were applied, too (python path, bash-isms, etc).

- 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.
llvm-svn: 162633
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).

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.

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.
