This turns gdbpy_ref into a template class, so that it can be used to
wrap subclasses of PyObject. The default argument remains PyObject;
and this necessitated renaming uses of "gdbpy_ref" to "gdbpy_ref<>".

2017-02-10 Tom Tromey <tom@tromey.com>
* python/py-ref.h (gdbpy_ref_policy): Now a template.
(gdbpy_ref): Now a template; allow subclasses of PyObject to be
used.

varobj.c: Change gdbpy_ref to gdbpy_ref<>.
This changes the event code in the Python layer to use
gdbpy_ref, simplifying the logic in many places.
It also changes evpy_emit_event not to steal a reference to its
argument. This is simpler to do now that gdbpy_ref is in use;
it's also a reasonable cleanup in its own right. While doing this I
realized that evpy_emit_event should not be calling gdbpy_print_stack
(all the outermost callers do this if needed), so I removed this as
well.

This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
In C, we can forward declare static structure instances. That doesn't
work in C++ though. C++ treats these as definitions. So then the
compiler complains about symbol redefinition, like:
src/gdb/elfread.c:1569:29: error: redefinition of ‘const sym_fns elf_sym_fns_lazy_psyms’
src/gdb/elfread.c:53:29: error: ‘const sym_fns elf_sym_fns_lazy_psyms’ previously declared here
The intent of static here is naturally to avoid making these objects
visible outside the compilation unit. The equivalent in C++ would be
to instead define the objects in the anonymous namespace. But given
that it's desirable to leave the codebase compiling as both C and C++
for a while, this just makes the objects extern.
(base_breakpoint_ops is already declared in breakpoint.h, so we can
just remove the forward declare from breakpoint.c)
