When ResetCurrentRequest is called, or IgnoreClient is called when a client has input pending, IgnoredClientsWithInput will be set. However, a subsequent IgnoreClient request will clear the client fd from that fd set, potentially causing the client to hang. So add an Ignore/Attend count, and only apply the ignore logic on the first ignore and the attend logic on the last attend. This is consistent with the comments for these functions; callers must pair them. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=27035.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
