aio / timers: Rearrange timer.h & make legacy functions call non-legacy
Rearrange timer.h so it is in order by function type. Make legacy functions call non-legacy functions rather than vice-versa. Convert cpus.c to use new API. Signed-off-by: Alex Bligh <alex@alex.org.uk> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
