Changeset 58891 in vbox for trunk/include

Message:

dbgf.h: Extended DBGFEVENTTYPE with a bunch of events that may be useful. The CPU exceptions (DBGFEVENT_XCPT_XXX) are of immediate use. Events starting with DBGFEVENT_FIRST_SELECTABLE are envisioned being configured via a single API operating on some bitmask and making HM, IOM, ++ notifications calls to let the components update cached state/whatever. The interrupt events would require it's own API, that operates on a 32 byte bitmap with a bit counter for optimizations. The I/O and MMIO events should be added to the DBGFR3BpXxx API and added as two new DBGFBP variants.
