Case tables are char-tables now.

to Fupcase_initials and Fupcase_initials_region for consistency.

Use EMACS_INT for comparing pointers.

(save_search_regs): Set them to 0 here.

And no need to BLOCK_INPUT for that.
(compile_pattern_1): Instead of here.

when a filter or sentinel tries to modify it.

(compile_pattern_1): New arg `posix'.  Controls the syntax spec
for parsing; also record it in the cache.
(compile_pattern): New arg `posix'.
(looking_at_1, string_match_1, fast_string_match): Pass 0 for new arg.
(search_buffer): New arg `posix'.  Now static.
(search_command): New arg `posix'.  All callers changed.
(Fposix_search_forward, Fposix_search_backward): New functions.
(string_match_1, looking_at_1): New subroutines broken out.
(Fstring_match, Flooking_at): Use them.
(Fposix_string_match, Fposix_looking_at): New functions.
(syms_of_search): defsubr new functions.

search_fastmap.
(syms_of_search): Initialize it.
(searchbuf_head): New variable.
(compile_pattern_1): Renamed from compile_pattern and made static.
Copy the regexp string in case the caller modifies it in place later.
(compile_pattern): New code, uses a cached entry if one is available.
The pattern buffer is now a return value instead of an arg.
(set_search_regs): Set num_regs directly, since there's no active
pattern buffer to pass to re_set_registers.
(Fstore_match_data): Likewise.
(Flooking_at): Use the new calling convention for compile_pattern.
(Fstring_match, fast_string_match, search_buffer): Likewise.

back on by setting it to allow_quit, never 1.

(find_before_next_newline): Declare the arguments' types explicitly;
don't let them default to int.

(max, min): Make these functions, not macros; we'd like to pass
them arguments that would be bad to evaluate more than once.
(newline_cache_on_off): New function.
(scan_buffer): New argument END.  Call newline_cache_on_off.  If
this buffer's newline cache is enabled, consult it to see if we
need to scan a region for newlines, and store information in the
cache after doing so.
(find_next_newline): Pass new arg to scan_buffer.
(find_before_next_newline): New function.

Use new accessor macros instead of calling XSET directly.

(search_buffer): Don't depend on internal format of re_pattern_buffer.
