  for TruffleRuby and JRuby.

Fix load catch table write barrier

I tried fixing this in 521b2fcba4e96898bfd237c79f17f19530b7a030, but
re-running wbcheck with the stricter WBCHECK_VERIFY_AFTER_WB, revealed
that this write barrier was fired too early, before the object was
actually written to the parent....

Fix write barriers in rb_hash_add_new_element

The write barriers must be run after the st_update callback returns,
as the objects are not on the object until then and there may be
allocation when there is a new object inserted.

This is hard to reproduce, and I haven't seen an actual crash due to it,...

Disallow forking from non-main ractor

[Bug #17516]

fork(2) only leave the calling thread alive in the child.
Because of this forking from the non-main ractor can easily
leave the VM in a corrupted state.

It may be possible in the future to carefully allow forking from non-main...

Reduce exposure of FL_FREEZE

The FL_FREEZE flag is redundant with SHAPE_ID_FL_FROZEN, so
ideally it should be eliminated in favor of the later.

Doing so would eliminate the risk of desync between the two, but
also solve the problem of the frozen status being global in namespace...

[ruby/json] Deprecate duplicate keys in object

There are few legitimate use cases for duplicate keys, and can
in some case be exploited.

Rather to always silently accept them, we should emit a warning,

Shink RClass when it is known they can't be namespaced

Even when namespaces are enabled, only a few core classes created
during init will eventually be namespaced.

For these it's OK to allocate a 320B slot to hold the extra namespace

But for any class created post init, we know we'll never need the...

Optimize rb_namespace_available

Rather than to lazily check the env using a trinary
value, we can more straightforwardly check for the
env during the VM boot.

This allow rb_namespace_available to just be a pointer

Avoid allocation for positional splat for literal array keyword argument
