[OBV] Remove some unnecessary code

[OBV] Remove some unnecessary code

[Tom Tromey]

This patch removes some unnecessary code.  In particular,
terminate_minimal_symbol_table is declared in minsyms.h, so it doesn't
need to be declared in objfiles.h as well.  And,
restore_ui_out_closure was rendered unnecessary by an earlier patch,
so the structure definition can be removed now.

I'm checking this in as obvious.

Tested by rebuilding on x86-64 Fedora 24 with --enable-targets=all;
which would notice any missing includes of minsyms.h.

	* utils.c (struct restore_ui_out_closure): Remove.
	* objfiles.h (terminate_minimal_symbol_table): Don't declare.
