[PATCH] helperHandleRead: unexpected read from ssl_crtd

There is a bug in current ssl_crtd code. The bug descriptions exists here:
   http://bugs.squid-cache.org/show_bug.cgi?id=3214
A patch fixing the bug uploaded here.

I am also posting the patch here, because it changes a little the
helpers behaviour, so maybe a discussion required. This patch add the
possibility to use other characters than the '\n' as the end of helper
response mark.
