Add filter function in orde to achieve the exact opposite of filter_except

[tmagnien]

Hi,

To keep some cookies, we need to use filter_except() function on a list, but to delete cookies we need to iterate on indivudual delete() function. Addind a filter() function that is the exact opposite of filter_except() allows for use of the same logic (and eases templating VCLs when needed).

Best regards,
Thierry

Would be great to get this functionality. Any chance of rebasing this @tmagnien so that it might be possible to merge. @lkarsten is this a changeset that interests you?

Hi, if @lkarsten is interested, I can update my code, yes.
