[PATCH] Move functions declarations to header file

[Glauber de Oliveira Costa <gcosta@redhat.com>]

Some interrupt entry points are currently defined in i8259.c
They probably belong in a header. Right now, their only user is
init_IRQ, justifying their declaration in-file. But when virtualization
comes in, we may be interested in using that functions in late
initializations.
