[patch] remove some unused python functions

[Jan Kratochvil <jan dot kratochvil at redhat dot com>]

Hi,

with --without-python:

cc1: warnings being treated as errors
varobj.c:765: error: ‘instantiate_pretty_printer’ defined but not used
varobj.c:906: error: ‘install_dynamic_child’ defined but not used


Thanks,
Jan

	* varobj.c (varobj_add_child, install_dynamic_child): Wrap into #if
	HAVE_PYTHON.
	(instantiate_pretty_printer): Move HAVE_PYTHON outside of the function.
