[PATCH 2/3] [python] Create gdb.pretty.register.

A common gdb.pretty.register function serves two purposes: reduces redundant
code and makes registering more concise for the files.

Instead of

     def register_printers (objfile):
	 objfile.pretty_printers.add (str_lookup_function)

repeated in all the pretty printer code and

     import gdb.libstdcxx.v6
     gdb.libstdcxx.v6.register_printers (gdb.current_objfile ())
     import gdb.otherprinter
     gdb.otherprinter.register_printers (gdb.current_objfile ())

in the files

     import gdb.pretty
     gdb.pretty.register ('gdb.libstdcxx.v6.printers', gdb.current_objfile ())
     gdb.pretty.register ('gdb.otherprinter', gdb.current_objfile ())

Is only required in the files.  This requires the convention that
a function called 'lookup_function' exists the pretty-printer module.
