RFC: Allow symbol_file_add to take section_offsets table

[Jim Blandy <jimb at redhat dot com>]

2002-11-25  Jim Blandy  <jimb@redhat.com>

	* symfile.c (symbol_file_add_with_addrs_or_offsets): New function,
	like the old symbol_file_add, but taking new arguments: you can
	now pass in either a `struct section_addr_info' list to say where
	each section is loaded, or a `struct section_offsets' table.  Pass
	these new arguments through to syms_from_objfile as appropriate.
	(symbol_file_add): Just call symbol_file_add_with_addrs_or_offsets, 
	with the appropriate quiescent values for the new arguments.
