o Save domains in jars like Mozilla does. It means all domains set in
Set-Cookie: headers are dot-prefixed.
o Save and use the 'tailmatch' field in the Mozilla/Netscape cookie jars (the
second column).
o Reject cookies using illegal domains in the Set-Cookie: line. Concerns
both domains with too few dots or domains that are outside the currently
operating server host's domain.
o Set the path part by default to the one used in the request, if none was
set in the Set-Cookie line.
to read multiple cookie files, no longer writes to the URL string passed
to the _add() function. The new stuff is now conditionally compiled on the
COOKIE define. Changed the _init() proto.
