	* options.h (class General_options): Add --incremental-base.
	* output.cc (Output_file::Output_file):
	(Output_file::open_base_file): Add base_name and writable parameters;
	read base file into new file; print error message here.
	(Output_file::map_no_anonymous): Add writable parameter; adjust all
	callers.
	* output.h (Output_file::open_for_modification): Rename to...
	(Output_file::open_base_file): ...this; add base_name and
	writable parameters; adjust all callers.
