Add additional Fiber scheduler hooks #9275
Description
Ruby 4.0 has expanded the callbacks for the Fiber scheduler, and we are missing some. At the very least, the following tests fail, probably because read and write are not fully hooked up to the scheduler:
6) Failure:
TestFiberScheduler#test_io_read_error [/home/runner/work/jruby/jruby/test/mri/fiber/test_scheduler.rb:339]:
Expected #<SystemCallError: Unknown error (SystemCallError) - /tmp/ruby_test_io_read_error_60db71be21beca0fb478a5f9aca41e06> to be a kind of Errno::EBADF, not SystemCallError.
7) Failure:
TestFiberScheduler#test_io_write_error [/home/runner/work/jruby/jruby/test/mri/fiber/test_scheduler.rb:360]:
Expected #<SystemCallError: Unknown error (SystemCallError) - /tmp/ruby_test_io_write_error_4c68306821923f764cae5d5dbee9cc2a> to be a kind of Errno::EINVAL, not SystemCallError.
8) Failure:
TestFiberScheduler#test_io_write_on_flush [/home/runner/work/jruby/jruby/test/mri/fiber/test_scheduler.rb:312]:
<[[:io_write, 55, "foo"], [:io_write, 55, "bar"]]> expected but was
<[]>.
9) Failure:
TestFiberScheduler#test_io_write_flush_error [/home/runner/work/jruby/jruby/test/mri/fiber/test_scheduler.rb:381]:
Expected nil to be a kind of Errno::EINVAL, not NilClass.
These need to be hooked up and made to pass.
