vmeUniverse/vmeUniverse.c, vmeUniverse/vmeUniverse.h,
vmeUniverse/vme_amd_defs.h: No longer enable posted-writes
on master windows (creates race-condition on memory-mapped
devices). A new flag allows for signalling that a window
maps 'ordinary memory'. Disable VME IRQ level if no
handler is registered with interrupting vector.
