cppspec.c: Do not use 'legal' or 'illegal' in error messages
and comments.
* cppmain.c (cb_define, cb_undef): Don't generate any output
if not done_initializing.
* cpplex.c (maybe_paste_with_next): When the token after a ##
is an omitted rest argument, only delete the token before it
if that token is a comma. Do not warn about bogus token
pastes for , ## rest_arg.

* cpphash.c: Don't include hashtab.h. Most macro-handling code
moved to cppmacro.c.
(hash_HASHNODE, eq_HASHNODE, _cpp_dump_macro_hash,
dump_hash_helper): Delete.
(expand_hash, higher_prime_number, _cpp_lookup_with_hash,
cpp_forall_identifiers): New. Implement specialized version of
Vlad's expandable hash table.

(_cpp_init_macros, _cpp_cleanup_macros): Adjust for new
implementation.
* cppmacro.c: New file.
* cppinit.c (dump_macros_helper): New.
(cpp_finish): Iterate over the identifier table directly.
* cpplex.c (parse_name): Calculate the hash of the identifier
while we scan it. Use _cpp_lookup_with_hash when we can.
* cpphash.h: Update prototypes.
(xcnewvec, HASHSTEP): New helper macros.
* cpplib.h: Update prototypes.
* Makefile.in (LIBCPP_OBJS): Add cppmacro.o.
(cppmacro.o): New rule.
(cpphash.o): Update deps.

* cpplib.c: Change all directive-handler functions to return
void, not int.
* cpphash.h: Update typedefs.
From-SVN: r35113
* cpplex.c (cpp_output_tokens, cpp_scan_buffer_nooutput): New public
interfaces.
(safe_fwrite, output_line_command): New static functions.
(cpp_expand_to_buffer): Now private to cpplib.
(cpp_scan_buffer): Take a printer.
* cpphash.h: Update prototypes.
* cpplib.h: Update prototypes.
(cpp_printer): New.
(cpp_buffer): Remove last_nominal_fname.
(cpp_reader): Remove lineno.
* cppmain.c: Use a cpp_printer.
* fix-header.c: No need to inhibit line commands. Call
cpp_start_read with no printer.
* cpperror.c (cpp_notice_from_errno): Provide default name.
* cppfiles.c (make_IHASH, _cpp_fake_ihash): New functions.
(find_include_file, cpp_read_file): Use make_IHASH.
(file_cleanup): Set control_macro and clear
input_stack_listing_current here.
(_cpp_execute_include): Don't output entering-file marker.
* cpphash.c (special_symbol): Look for the line number in the
buffer, not the reader.
(_cpp_macroexpand): No need to disable line commands.
(_cpp_dump_definition): No need to generate line commands.
(dump_hash_helper): Remove excess newline from output.
* cppinit.c (dump_special_to_buffer): No need to generate line
commands.
(cpp_printer_init): New.
(cpp_start_read): Take a printer, and start it up if it's not
NULL. No need to generate line commands.
(cpp_finish): Expect no buffers stacked at all. Take a
printer argument, and flush the output buffer if it's not
NULL.
* cpplex.c (_cpp_lex_token): Return EOF if there's no buffer.
Don't put two hashes at the beginning of an assertion.
(cpp_get_token): Don't increment pfile->lineno or emit line
commands here. Return EOF if there's no buffer when we get
EOF.
* cpplib.c (do_define, skip_if_group):
No need to disable line commands.
(_cpp_output_line_command): Delete function.
(do_line): Don't emit line commands here, but set things up so
they will be emitted if necessary. Use _cpp_fake_ihash to
make unique nominal_fnames if necessary.
(do_elif, do_else, _cpp_handle_eof): Call cpp_error_with_line
with 0 for column, not -1.
(_cpp_handle_eof): Don't set the control macro here. Don't
clear input_stack_listing_current here. Don't emit line
commands.
