TarReader#each previously implemented a partial version of seek.
This code moved to Entry#seek for use from TarReader#each.
Entry#close now returns nil instead of true, like IO#close.
Closing an Entry now seeks to the end of the Entry, seeking past
any remaining zero byte tar file padding and moving the io to the
correcty position to read the next file in the archive.
Uses seek for Entry#rewind and #pos=, fixing the tar->gzip->tar nested
rewind that would break previous to this change.
Add Entry.open that behaves more like File.open.

If you have a method that takes rest arguments and a splat call that
happens to line up perfectly with that rest, you can just dupe the
array rather than move anything around. We still have to dupe, because
people could have a custom to_a method or something like that which
means it is hard to guarantee we have exclusive access to that array.
Example:
```ruby
def foo(a, b, *rest)
end
foo(1, 2, *[3, 4])
```
This commit adds a function rb_data_free used by obj_free and
rb_objspace_call_finalizer to free T_DATA objects. This change also
means that RUBY_TYPED_FREE_IMMEDIATELY objects can be freed immediately
in rb_objspace_call_finalizer rather than being created into a zombie.
If the original `BUNDLE_GEMFILE` is different from the default, then the
suggestion wouldn't work as is.

It's possible (but very rare) to have a race condition between setting
`mutex->fiber = NULL` and `thread_mutex_remove(th, mutex)` which results
in the following bug:
```
[BUG] invalid keeping_mutexes: Attempt to unlock a mutex which is not locked
```
Fixes <https://bugs.ruby-lang.org/issues/19480>.
This feature was introduced in commit 2ccf6e5, but I realized that
using rb_warn is a bad idea because it allocates objects, which causes
a different crash ("object allocation during garbage collection phase").
We should just hard crash here instead.
```
1) Failure:
TestThreadInstrumentation#test_thread_instrumentation [/tmp/ruby/src/trunk-repeat20-asserts/test/-ext-/thread/test_instrumentation_api.rb:33]:
Call counters[4]: [3, 4, 4, 4, 0].
Expected 0 to be > 0.
```
We fire the EXIT hook after the call to `thread_sched_to_dead` which
mean another thread might be running before the `EXIT` hook have been
executed.
