* tools/rfc822parse.c (HEADER_NAME_CHARS): New. Taken from
mime-maker.c.
(rfc822_valid_header_name_p): New. Based on code from mime-maker.c.
(rfc822_capitalize_header_name): New. Copied from mime-maker.c.
(capitalize_header_name): Remove. Replace calls by new func.
(my_toupper, my_strcasecmp): New.
* tools/mime-maker.c: Include rfc822parse.h.
(HEADER_NAME_CHARS, capitalize_header_name): Remove.
(add_header): Replace check and capitalization by new functions.
--
This is a straightforward change with two minor chnages:
- In rfc822parse.c the capitalization handles MIME-Version special.
- The check in mime-maker bow detects a zero-length name as invalid.
my_toupper and my_strcasecmp are introduced to allow standalone use
of that file.
