Log:
Fiber scheduler: invoke `#io_write` hook on IO flush (#15609)
Previously, calling IO#flush or closing an IO with unflushed buffered
writes would just invoke `#blocking_operation_wait` and flush the write
buffer using a `write` syscall. This change adds flushing through the
fiber scheduler by invoking the `#io_write` hook.
* Prefer IO::Buffer#write in IOScheduler
* Use Dir.tmpdir for test file
* Correctly handle errors in io_flush_buffer_fiber_scheduler
Modified files:
io.c
test/fiber/scheduler.rb
test/fiber/test_scheduler.rb
