    Bug #671172 - camel: smtp: Make EHLO keywords check case insensitive
    
    According to section 4.1.1.1 of RFC 2821 (last paragraph,
    see tools.ietf.org/html/rfc2821#section-4.1.1.1):
    
       Although EHLO keywords may be specified in upper, lower, or mixed
       case, they MUST always be recognized and processed in a case-
       insensitive manner.  This is simply an extension of practices
       specified in RFC 821 and section 2.4.1.
    
    Current smtp_helo() implementation is using strncmp() - replace them
    with g_ascii_strncasecmp().
