winmm split

before (finally ;-) really splitting the core of the winmm/mmsystem
code, let's first start by moving the largest part of the 16 bit code
(mainly the message mapping) into 16 bit only files
this will be made out of three patches:
mm1632_d: moving driver message mapping out of 32 bit code
mm1632_m: moving MCI message mapping out of 32 bit code
mm1632_l: moving low level multimedia message mapping out of 32 bit code
patches must be applied in the d/m/l order
the attached patch is the d (driver one)
A+
