ObjFW  History of src/forwarding/apple-forwarding-ppc.S of c6a65ca7a689eb19

Forgot to add 2017, even though I already did quite some changes in
2017. file: [d88f9fb209] check-in: [44f45c2e35] user: js, branch: trunk, size: 4273 [annotate] [blame] [check-ins using] [diff]

While at it, also update the mail address. file: [744c0f51ae] check-in: [2a27cf3000] user: js, branch: trunk, size: 4267 [annotate] [blame] [check-ins using] [diff]

This is not strictly needed (and means its even included twice, as
forwarding.S already includes config.h), but it helps to assemble the
file directly without going through forwarding.S. file: [6cdc68d385] check-in: [9a4792a99e] user: js, branch: trunk, size: 4257 [annotate] [blame] [check-ins using] [diff]

It matches the Apple API and ABI now and the forwarding handler itself
determines whether it should forward or not.

This moves handling of +[resolve{Class,Instance}Method:] to the runtime
and allows adding new kinds of forwarding without changing the runtime.

Also fixes a potential stack problem in the forwarding for MIPS. file: [744faa6cfb] check-in: [0c332aa2d2] user: js, branch: trunk, size: 4321 [annotate] [blame] [check-ins using] [diff]
