Removed. (check_html_charset): Replaced with this.

2001-07-12  Not Zed  <NotZed@Ximian.com>

        * camel-mime-part-utils.c (extract_metatag_charset): Removed.
        (check_html_charset): Replaced with this.
        (simple_data_wrapper_construct_from_parser): Call
        check_html_charset if we dont have a charset on the content-type,
        and we have text/html data.
        (check_html_charset): We also need to do qp/base64 decoding
        ourselves, sigh.

        * camel-mime-utils.c (html_meta_param_list_decode): Removed.  This
        was very wrong, the rules for mail headers vastly different from
        rules for decoding html elements.
        (rfc2184_decode): Move the malloc inside the iconv_open worked,
        otherwise we have a memleak.

        * camel-mime-filter-html.c (camel_mime_filter_html_finalize, init,
        run, reset): Changed to use camelhtmlparser, and fixed a tiny
        memleak.

        * camel-html-parser.c: Made the html indexer tokeniser re-usable.
        ONLY TO BE USED INTERNAL TO CAMEL HOWEVER.
        (tokenise_step): Slight fix to non-quoted values.
