* cpplib.h: Delete struct import_file. Add ihash element to
struct cpp_buffer. Delete dont_repeat_files and
import_hash_table elements from cpp_reader; change
all_include_files to a hash table. Delete all foobar_include
/ last_foobar_include elements from struct cpp_options; put
back four such: quote_include, bracket_include,
system_include, after_include. Redo struct file_name_list
completely. Add new structure type include_hash. Add
prototypes for merge_include_chains and include_hash. Change
prototypes for finclude, find_include_file, and
append_include_chain to match changes below.

(add_import, lookup_import, open_include_file): Removed.
(INO_T_EQ): Define this (copied from cccp.c).
(hack_vms_include_specification): Remove all calls and #if 0
out the definition. It was being called incorrectly and at
the wrong times. Until a VMSie can look at this, it's better
to not pretend to support it.
(append_include_chain): Change calling convention; now takes
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.
(file_cleanup): Decrement pfile->system_include_depth here if
it's >0.
(find_include_file): Calling convention changed; now passes
around a struct include_hash instead of 3 separate parameters.
Guts ripped out and replaced with new include_hash mechanism.
(finclude): Calling convention changed as for
find_include_file. Error exits pulled out-of-line. Reformat.
(safe_read): Return a long, not an int.

* cpplib.c (is_system_include): Deleted.
(path_include): Fix up call to append_include_chain.
(do_include): Fix up calls to find_include_file and finclude.

#import warning message. Don't decrement
pfile->system_include_depth here.
(do_pragma): Understand the include_hash structure. Reformat.
(do_endif): Correct handling of control macros. Understand
the include_hash.
(cpp_start_read): Fix up calls to finclude. Call
merge_include_chains.
(cpp_handle_option): Fix up calls to append_include_chain.
Understand the four partial include chains.
(cpp_finish): Add debugging code (#if 0-ed out) for the
include_hash.
(cpp_cleanup): Free the include_hash, not the import hash and
the all_include and dont_repeat lists which no longer exist.
