only one directory at a time, and sets up the data structure
itself.
(redundant_include_p): Rewritten - this is now used for all
include redundancy, whether by #ifndef, #import, or #pragma
once. Looks up things in the include hash table.

(do_endif): Correct handling of control macros. Understand
the include_hash.
(cpp_start_read): Fix up calls to finclude. Call
merge_include_chains.

Understand the four partial include chains.
