It is also useful if we want to implement multi-threading on top of Boost.

I also reduced the stack size to 8 Mb in the tests at tests/lean and tests/lean/slow. The idea is to simulate stackoverflow conditions.

When LEAN_THREAD_UNSAFE=ON, we:
- Do not run tests at tests/lua/threads
- Disable thread object at Lua API
- par tactical becomes an alias for interleave
- Disable some unit tests that use threads

Recursive functions that may go very deep should invoke the function check_stack. It throws an exception if the amount of stack space is limited.
The function check_system() is syntax sugar for
check_interrupted();
check_stack();
