config: add means of enabling/disabling wsdl (and cautionary note about SDL on windows)

wsdl: fix mouse trouble related to shutdown, use wmi instead of ddraw,
disable low-level kbd hook (not needed), cleanup

// enable the wsdl emulator in Windows builds.
//
// NOTE: the official SDL distribution has two problems on Windows:
// - it specifies "/defaultlib:msvcrt.lib". this is troublesome because
// multiple heaps are active; errors result when allocated blocks are
// (for reasons unknown) passed to a different heap to be freed.
// one workaround is to add "/nodefaultlib:msvcrt.lib" to the linker
// command line in debug configurations.
// - it doesn't support color hardware mouse cursors and clashes with
// cursor.cpp's efforts by resetting the mouse cursor after movement.
#ifndef CONFIG_USE_WSDL
# define CONFIG_USE_WSDL 1

// enable additional debug checks (very slow).
