2002-09-20  Fernando Nasser  <fnasser@redhat.com>

         * source.c: Make global variables current_source_symtab and
         current_source_line static.
         (list_command): Moved to cli/cli-cmds.c.
         (ambiguous_line_spec): Moved to cli/cli-cmds.c.
         (get_first_line_listed): New accessor function.
         (get_lines_to_list): New accessor function.
         (get_current_source_symtab_and_line): New function. Retrieves the
         position in the source code that we consider current.
         (get_current_or_default_source_symtab_and_line): New function.
         Like the above but attempts to determine a default position if one
         is not currently defined.
         (set_current_source_symtab_and_line): New function. Sets the source
         code position considered current and returns the previously set 
one.
         (clear_current_source_symtab_and_line): Reset stored 
information about
         a current source line.
         (_initialize_source): Remove registration for the "list" 
command and
         its alias.
         * source.h: Add declarations for the new functions above.
         * symtab.h: Remove declarations for the global variables mentioned
         above.
         * breakpoint.c (parse_breakpoint_sals): Use accessor functions to
         obtain current source line.
         * linespec.c (decode_line_1): Ditto.
         * macroscope.c (default_macro_scope): Ditto.
         * scm-lang.c (scm_unpac): Ditto.
         * stack.c (print_frame_info_base): Ditto.
         * symfile.c (clear_symtab_users): Ditto.
         * symtab.c (decode_line_spec): Ditto.
         * cli/cli-cmds.c (list_command): Moved here from source.c.
         (ambiguous_line_spec): Moved here from source.c.
         (_init_cli_cmds): Add definition for "list" and its alias.
         * Makefile.in: Update dependencies.
