Tom Tromey 0f6ed0e0ef Fix PR python/19438, PR python/18393 - initialize dictionaries 
This fixes PR python/19438 and PR python/18393.  Both bugs are about
invoking dir() on some Python object implemented by gdb, and getting a
crash.

The crash happens because the dictionary field of these objects was
not initialized.  Apparently what happens is that this field can be
lazily initialized by Python when assigning to an attribute; and it
can also be handled ok when using dir() but without __dict__ defined;
but gdb defines __dict__ because this isn't supplied automatically by
Python.

The docs on this seem rather sparse, but this patch works ok.

An alternative might be to lazily create the dictionary in
gdb_py_generic_dict, but I went with this approach because it seemed
more straightforward.

Built and regtested on x86-64 Fedora 23.
