* this symbol is a server configuration flag (can be passed via cmdline) for limiting the max size of big-requests. there shouldn't be any need to use it outside the core X server (in server modules like drivers or external extension) - therefore unexport it * in order to reduce namespace pollution of public (server module API) headers, create a new internal header for those tings (more to come) Signed-off-by: Enrico Weigelt, metux IT consult <info@metux.net> Part-of: <https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/1275>
