better Mac thread support: earlier ptrhead interception, and intercept workqueue threads and raw Mach threads #1403

For initial thread support to get simple pthreads apps working I'm just planning to intercept bsdthread_create(). This intercepts threads a little late, and misses workqueue threads. But we need earlier injection in order to intercept bsdthread_register() and intercept the entries for both regular and workqueue threads.

We also want to eventually handle raw Mach threads created via other means.

When we terminate a thread on MacOS we fail to free the app's stack: we need to pass the stack base and size to bsdthread_terminate.
