3b5c1c4203 beam: more hooks for interactive debugging
This inserts low-level hooks for interactive step-by-step debugging.
Hooks are triggered by setting the *TEST* environment variable.

This is particularly useful for tracking down file descriptor leaks,
double-closing, or other issues which are difficult to debug with
the usual toolbox.

a14c83eca3 beam/examples/beamsh: first try at nested execution
The "wiring" is broken because engine does not keep a reference for handling introspection calls.

932149b2a7 Beam: a simple stream-oriented communication protocol for distributed systems.
This patch includes a stripped down implementation with a bare minimum
unix socket transport. It relies on fd passing for stream multiplexing.

The purpose of this first patch is to allow implementation of dynamic
linking, which will allow advanced service discovery.
