Python scripting: Add new method Value.referenced_value to
gdb.Value which can dereference pointer as well as reference
values.
* NEWS: Add entry under 'Python scripting' about the new method
Value.referenced_value on gdb.Value objects.
* python/py-value.c (valpy_referenced_value): New function
defining a new method on gdb.Value objects which can dereference
pointer and reference values.
* testsuite/gdb.python/py-value.cc: Add test case for
testing the methodology exposing C++ values to Python.
* testsuite/gdb.python/py-value-cc.exp: Add tests testing the
methodology exposing C++ values to Python.
* testsuite/gdb.python/Makefile.in: Add py-value-cc to
EXECUTABLES.
* docs/gdb.texinfo (Python API/Values From Inferior): Add
description about the new method Value.referenced_value. Add
description on how Value.dereference is different (and similar)
to Value.referenced_value.
