To libify `git apply` functionality we must make 'struct apply_state'
usable outside "builtin/apply.c".

Why is this patch plopped right in the middle of a bunch of other
patches which are making functions return -1 rather than die()ing?
Seems out of place.

Let's do that by creating a new "apply.h" and moving
'struct apply_state' there.

I could easily see this header introduced at a very early stage when
'struct apply_state' itself is introduced, rather than introducing
'struct apply_state' in builtin/apply.c and later moving it here.
