Commit a9ad427 introduced a bug that assumed the cookie value was at least
one character, but the cookie value can also be empty.
RFC 6265 5.2 does not specify any special behavior for double quotes and as
such they should be considered part of the value. This change stops
stripping those double quotes and instead preserves them.
The io/http_cookie_test test was skipped because it was considered flaky.
This change dusts it off and tests the new behavior.
This change adds the exact offsets and source to the FormatExceptions to
help the caller understand why a malformed cookie was rejected.
