Fix coroutine copy implementation on OpenBSD

2019-12-27T23:01:01+00:00

OpenBSD is the only platform that uses this support by default,
and it did not work because while OpenBSD supports alloca, it does
not include alloca.h.

This should be backported to Ruby 2.7.

From George Koehler

Add assertions to `coroutine_initialize_main`.

Split assertions to check which one fails.

Make fiber_pool more conservative on platforms with limited address space.

2019-07-18T08:54:55+00:00

We use COROUTINE_LIMITED_ADDRESS_SPACE to select platforms where address
space is 32-bits or less. Fiber pool implementation enables more book
keeping, and reduces upper limits, in order to minimise address space
utilisation.

Stack copying implementation of coroutines.
