Checks cookie array for correctness, possibly updating its 'domain', 'path' and 'expires' fields

The checks are as follows:
- cookie array should contain 'name' and 'value' fields;
- name and value should not contain disallowed symbols;
- 'expires' should be either empty parseable by DateTime;
- 'domain' and 'path' should be either not empty or an URL where
cookie was set should be provided.
- if $setter is provided, then document at that URL should be allowed
to set a cookie for that 'domain'. If $setter is not provided,
then no domain checks will be made.

'expires' field will be converted to ISO8601 format from COOKIE format,
'domain' and 'path' will be set from setter URL if empty.
