C99 fix


Fix some style


mod_proxy_html: follow up to r1599012.

To determine whether or not HTML data are lower than 4 bytes, use a retain
buffer rather than assuming that all should be contained in a single bucket
with the next one being EOS (if any).


mod_proxy_html: don't depend on NUL terminated bucket data.

ap_regexec() wants NUL terminated strings, so use ap_regexec_len() instead.
