Process.detach: avoid singleton class creation

* process.c (Init_process): subclass Thread as Process::Waiter
  (rb_detach_process): use Process::Waiter instead of singleton class

* test/ruby/test_process.rb (test_process_detach): new test

* inits.c (rb_call_inits): call Init_Thread before Init_process to
  ensure Process::Waiter may be a subclass of Thread

Thanks to headius for reporting [Bug #10231]
Thanks to nobu for review of my initial patch.

proc.c (rb_proc_alloc): inline and move to vm.c

* proc.c (rb_proc_alloc): inline and move to vm.c
  (rb_proc_wrap): new wrapper function used by rb_proc_alloc
  (proc_dup): simplify alloc + copy + wrap operation
  [ruby-core:64994]

* vm.c (rb_proc_alloc): new inline function
  (rb_vm_make_proc): call rb_proc_alloc

* vm_core.h: remove rb_proc_alloc, add rb_proc_wrap

* benchmark/bm_vm2_newlambda.rb: short test to show difference

First we allocate and populate an rb_proc_t struct inline to avoid
unnecessary zeroing of the large struct.  Inlining speeds up callers as
this takes many parameters to ensure correctness.  We then call the new
rb_proc_wrap function to create the object.

rb_proc_wrap - wraps a rb_proc_t pointer as a Ruby object, but
we only use it inside rb_proc_alloc.  We must call this before
the compiler may clobber VALUE parameters passed to rb_proc_alloc.

proc/env DATA_PTR is never NULL

* proc.c (proc_free): remove, use RUBY_TYPED_DEFAULT_FREE
  (proc_mark, proc_memsize): remove needless branching

* vm.c (env_free): remove, use RUBY_TYPED_DEFAULT_FREE

This shows a tiny ~0.5% improvement in benchmark/bm_vm2_newlambda.rb
but also removes a lot of code.

vm.c (thread_alloc): remove needless volatile

If we needed a volatile there, every other alloc function would need it.
There is nothing special I can see about thread_alloc which would
justify it.

  [ccan 7ec5b8e06b2fd5fa98b1fcde1158c286d2d429d8] (David Gibson)

It's quite common to have a pointer which could be either a pointer to a
structure member, or NULL.  This needs special casing with container_of(),
or it will convert NULL into something strange.

This patch adds container_of_or_null(), which will return NULL if passed
(an appropriately typed) NULL, or the containining structure as
container_of() otherwise.
