Main: fix the remaining NULL safearray issues, the template had useless assertions and the helper code used by the wrappers also needed to check for it everywhere

file headers.

Wrapper.h: Fixed regression in IAppliance::importMachines where a NULL options array was causing assertions in debug builds despite working fine before conversion to wrappers. (tstOVF triggered it)

Main/include/Wrapper.h: fix reference counting issues for outgoing iface arrays, the shorter way to write the code handles this automatically

Main/Wrapper.h: fix evil typo

Main/idl/apiwrap-server: add support for providing hints to the wrapper generation, we'll sporadically need to get at the AutoCaller object so that we can call uninit().

Main: Code generator for (xp)com API implementations, including logging and parameter conversion, so far only used by MediumFormat. Next try, needed significant tweaks to work with xpcom (safearray handling fixes in the parameter conversion helpers), different STL implementation (which doesn't support declaring template type parameters as const), missing build dependencies (which didn't show on the dual core system used for writing the code), and finally the duplicate XPCOM classinfo and AddRef/Release/QueryInterface method definitions needed to be removed.

back out API wrapper generator, too broken with XPCOM
