Benjamin Peterson 4510e6de9d mark dtrace stubs as static inline; remove stubs
C99 inline semantics don't work everywhere. (https://bugs.python.org/issue28092)
We don't want these to have external visibility anyway.

Łukasz Langa a785c87d6e DTrace support: function calls, GC activity, line execution
Tested on macOS 10.11 dtrace, Ubuntu 16.04 SystemTap, and libbcc.

Largely based by an initial patch by Jesús Cea Avión, with some
influence from Dave Malcolm's SystemTap patch and Nikhil Benesch's
unification patch.

Things deliberately left out for simplicity:
- ustack helpers, I have no way of testing them at this point since
they are Solaris-specific
- PyFrameObject * in function__entry/function__return, this is
SystemTap-specific
- SPARC support
- dynamic tracing
- sys module dtrace facility introspection

All of those might be added later.
