lynx-dev (patch) fix cookies domains match case insensitively

[Leonid Pauzner]

> On our corporate internet, we have a domain (MMIT-SMDB.mcit.com) which
> we often refer to as mmit-smdb.mcit.com within links. As we understand
> it, case sensitivity does NOT apply to domains, either should work. The
> problem comes in Lynx when cookies are of different case than the link;
> lynx apparently thinks they are different domains, and doesn't send the
> cookies back when it needs to. Once we isolated the main problem on the
> server side (we were redirecting to a login screen, capturing
> ID/password, sending cookies, then redirecting back to the protected
> page), and fixed it by making sure redirects were always lower case
> (consistent with the prevailing casing for the domain), the problem went
> away.

> The question, however, remains: domains should NOT be case sensitive,
> and cookies should ignore case on domain names when deciding whether to
