[commit] misc minor guile cleanups

[Doug Evans <xdje42 at gmail dot com>]

Hi.

fyi, I have committed this.

For reference sake,
I have/had a few patches that use gdbscm_scm_to_target_string_unsafe
but they're not checked in so this function is currently unused.
It can be put back when checked in code uses it.

2014-05-21  Doug Evans  <xdje42@gmail.com>

	* scm-exception.c (gdbscm_invalid_object_error): Make result is void.
	(gdbscm_out_of_range_error): Ditto.
	(gdbscm_memory_error): Ditto.
	* scm-string.c (gdbscm_scm_to_target_string_unsafe): Delete.
	* guile-internal.h (gdbscm_invalid_object_error): Update.
	(gdbscm_out_of_range_error): Update.
	(gdbscm_memory_error): Update.
	(gdbscm_scm_to_target_string_unsafe): Delete.
