This adds a wrapper function inject_realmode_interrupt() around the

Really has no business in x86.c, as it's there to work around a vmx
specific problem.

Doesn't seem to add much value. I'd say just export emulate_int_real()
and call it from vmx.c.
Hmm, you aren't initializing the context. So I guess you do need this
function (and I guess it's better to keep it in x86.c near the rest of
the emulation stuff, just make sure the emulation context is initialized).

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.
