Remove all the __repr__ methods from the API/*.h files, and put them
into python-extensions.swig, which gets included into lldb.swig, and
adds them back into the classes when swig generates it's C++ file.  This
keeps the Python stuff out of the general API classes.

Also fixed a small bug in the copy constructor for SBSymbolContext.
