Wap cookies patch

Hi,

The following is a simple patch to align cookies with RFC 2068 (HTTP 1.1) & 2109 (cookie). It decreases memory requirements, processing time, and handles correctly cookies that have '=' in their values.

From RFC 2068: 

token          = 1*<any CHAR except CTLs or tspecials>

          tspecials      = "(" | ")" | "<" | ">" | "@"
                         | "," | ";" | ":" | "\" | <">
                         | "/" | "[" | "]" | "?" | "="
                         | "{" | "}" | SP | HT

From RFC 2109:

av-pairs        =       av-pair *(";" av-pair)
av-pair         =       attr ["=" value]        ; optional value
attr            =       token
value           =       word
word            =       token | quoted-string

Therefore in a NAME = VALUE pair in a cookie, NAME cannot contain any of those fancy characters.

Please vote and commit.

Thanx,
Nikos
