f05416c91f Fix coroutine copy implementation on OpenBSD 
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.

5e22f873ed decouple internal.h headers 
Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead.  This would significantly
speed up incremental builds.

We take the following inclusion order in this changeset:

1.  "ruby/config.h", where _GNU_SOURCE is defined (must be the very
    first thing among everything).
2.  RUBY_EXTCONF_H if any.
3.  Standard C headers, sorted alphabetically.
4.  Other system headers, maybe guarded by #ifdef
5.  Everything else, sorted alphabetically.

Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).

f4d9daf2b6 coroutine/ucontext/Context.c: define __EXTENSIONS__ explicitly 
instead of ruby/config.h, per samuel's request.

dbfd4b780e coroutine/ucontext/Context.c: Include "ruby/config.h" for Solaris 
getcontext, makecontext, and swapcontext seem to be available only when
`__EXTENSION__` is defined on Solaris.

853d91a04a Fix coroutine support on win32 
Ruby master branch currently fails on win32 MINGW at this spec:
https://github.com/ruby/spec/blob/master/core/thread/element_set_spec.rb

MINGW makes use of setjmp3() implemented in MSVCRT.DLL.
This function traverses the SEH list up to a terminating pointer 0xFFFFFFFF.
It therefore currently segfaults on NULL.
The SEH linked list must be terminated by 0xFFFFFFFF instead of NULL.

This fixes the issue mentioned here:

Make fiber_pool more conservative on platforms with limited address space. 
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.

518adcca0a: "Try using arm32 implementation for fibers."

It seems to cause SEGV consistently on Ubuntu armv7l eabihf:

c5fe904f6e Fix for coroutine/win32/Context.obj 
* coroutine/win32/Context.asm: old ml version 9 needs CPU
  directive before `.model` directive.

* win32/Makefile.sub: specify object directories to separate Win32
  and Win64 targets.  Win32 rule was overridden by Win64 rule and
  just ignored.
