The session ext currently munges into the linked list of headers itself, because the delete header API is given the key for headers to delete. The session ext wants to use a prefix past the colon separator, for i.e. "Set-Cookie: PHPSESSID=", to eliminate only the specific cookie rather than all cookies. This changes the SAPI code to add a new header op to take a prefix instead. Call sites are yet unchanged. Also fix some whitespace.
Use the modern SAPI header ops API, including the remove prefix op we just added.
The purpose of this is clear, and after refactoring, the special case is no longer there, so it has no value.
Suggestion from Jakub.
I don't think this needs to be special cased with the parameter.
Suggestion from Jakub.
It may be better to use spaces in here instead.

Refactoring this as part of triaging GH-18601 - I don't think it'll fix the issue, but it's a good idea to clean anyways. ext/session had its own copy of the remove header code, because the SAPI header op mandated it was just a name, and would remove all headers for that name. ext/session couldn't rely on this because it only wanted to remove a specific cookie, not all of them.
To simplify this, add a version of
SAPI_HEADER_DELETEthat is more flexible and allows for passing a prefix to check for, not just a name. This should work for removing a specific cookie from the headers. (Also fixes some whitespace too.)
