[RFA] print_frame_info_listing_hook cleanup

["Martin M. Hunt" <hunt@redhat.com>]

If print_frame_info_listing_hook is defined, print_source_lines()
does not get called from print_frame_info_base in stack.c.  
print_source_lines() sets the global current_source_symtab, which 
is evidently necessary to GDB.  To fix this problem, the Insight 
print_frame_info_listing_hook function sets current_source_symtab, 
which seems very inappropriate.  Therefore this proposed fix.

2002-02-06  Martin M. Hunt  <hunt@redhat.com>

	* stack.c (print_frame_info_base): When calling 
	print_frame_info_listing_hook, set current_source_symtab

2002-02-06  Martin M. Hunt  <hunt@redhat.com>

	* generic/gdbtk-hooks.c: Remove include of symtab.h.
	(gdbtk_print_frame_info): Don't set GDB globals
	current_source_symtab and current_source_line. Let
	GDB do it.
