e1cd1be6d6 Switching back to using std::tr1::shared_ptr. We originally switched away
due to RTTI worries since llvm and clang don't use RTTI, but I was able to 
switch back with no issues as far as I can tell. Once the RTTI issue wasn't
an issue, we were looking for a way to properly track weak pointers to objects
to solve some of the threading issues we have been running into which naturally
led us back to std::tr1::weak_ptr. We also wanted the ability to make a shared 
pointer from just a pointer, which is also easily solved using the 
std::tr1::enable_shared_from_this class. 

The main reason for this move back is so we can start properly having weak
references to objects. Currently a lldb_private::Thread class has a refrence
to its parent lldb_private::Process. This doesn't work well when we now hand
out a SBThread object that contains a shared pointer to a lldb_private::Thread
as this SBThread can be held onto by external clients and if they end up
using one of these objects we can easily crash.

So the next task is to start adopting std::tr1::weak_ptr where ever it makes
sense which we can do with lldb_private::Debugger, lldb_private::Target,
lldb_private::Process, lldb_private::Thread, lldb_private::StackFrame, and
many more objects now that they are no longer using intrusive ref counted
pointer objects (you can't do std::tr1::weak_ptr functionality with intrusive
pointers).

Fixed an issues with the SBType and SBTypeMember classes:
- Fixed SBType to be able to dump itself from python
- Fixed SBType::GetNumberOfFields() to return the correct value for objective C interfaces
- Fixed SBTypeMember to be able to dump itself from python
- Fixed the SBTypeMember ability to get a field offset in bytes (the value
  being returned was wrong)
- Added the SBTypeMember ability to get a field offset in bits


Cleaned up a lot of the Stream usage in the SB API files.

d9dc52dc4c Added the ability to get all section contents, or the section
contents starting at an offset (2 separate methods). This helps
the scripting interface stay more natural by allowing both from
Python.

Added the ability to dump data with address annotations when
call SBData::GetDescription().

Hooked up the SBSection to the __repr__ so you can print section
objects from within python.

Improved the dumping of symbols from python.

Fixed the .i interface references which were set to "Relative to this Group"
which somehow included Jim's "lldb-clean" root directory in the path. The
interfaces are now in a folder called "interfaces" withing the Xcode API
subfolder.

cac9c5f971 Added to the public API to allow symbolication:
- New SBSection objects that are object file sections which can be accessed
  through the SBModule classes. You can get the number of sections, get a 
  section at index, and find a section by name.
- SBSections can contain subsections (first find "__TEXT" on darwin, then
  us the resulting SBSection to find "__text" sub section).
- Set load addresses for a SBSection in the SBTarget interface
- Set the load addresses of all SBSection in a SBModule in the SBTarget interface
- Add a new module the an existing target in the SBTarget interface
- Get a SBSection from a SBAddress object

This should get us a lot closer to being able to symbolicate using LLDB through
the public API.
