Interrupt redirection support requires a new interrupt chip, which
needs to share data structures, constants and functions with the AVEC
code.

Move them to the header file and make the required functions public.

including:
1 marco AVEC_MSG_OFFSET
2 struct avecintc_data
3 Make avecintc_sync public
