[PATCH] Remove duplicate code to init python objfile/progspace objects

[Doug Evans <dje@google.com>]

Hi.

This patch just removes some duplicate code.

2014-10-09  Doug Evans  <dje@google.com>

	* py-objfile.c (objfpy_initialize): New function.
	(objfpy_new, objfile_to_objfile_object): Call it.
	* py-progspace.c (pspy_initialize): New function.
	(pspy_new, pspace_to_pspace_object): Call it.
