<rdar://problem/10126482>

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.
