clang-p2996/lldb/source/API/SBData.cpp
Greg Clayton 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.
