Fix xcb error ignoring
The existing mechanism with set_ignore_next() is (IMHO) ugly and also does not work with XCB requests. This commit adds a new function set_ignore_cookie() and fixes callers that were converted to XCB to use this new function instead. Signed-off-by: Uli Schlachter <psychon@znc.in>
