* Compatibility header.

* Four cases:
* GNU
* Uses the 'old' Object with API and ABI = 0.
* Compatibility methods are added.
* NeXT pre-Darwin9
* Uses the 'old' Object with API and ABI = 0.
* NeXT Darwin >= 9 with no implementation of ABI 2
* Uses API 2 and ABI 0 for m32, uses the 'old' Object'
* Uses API 2 for m64 but only compile tests can be expected to work.
* NeXT Darwin >= 9 with __OBJC2__
* Uses API 2 and ABI 0 for m32, uses the 'old' Object'
* Uses API 2 and ABI 2 - the libobjc implementation of Object is very
* basic, and we add a category to expand this for test-suite use.
