This moves the thread name setting code into the generic SPDK thread
setup code, so now all spdk_threads can be named, not just ones created
by the event framework.

Patch afe860ae deferred freeing the io_device. However, for nvme, the
io_device context (spdk_nvme_ctrlr) is still being destructed before
io_channels are destroyed, causing segfaults on hotremove.
This patch defers io_device context destruction and fixes nvme
hotremove.
Fixes: afe860aeb161 ("channel: Correctly defer unregisters if channels exist")
Fixes: 5533c3d2087b ("util: defer put_io_channel")

This is faster than spdk_get_thread(), which iterates over all of the
threads under a lock until it finds the current one.

A previous commit added use of 'bool' but did not add
a stdbool.h include. All files including io_channel.h
already were including stdbool.h, but adding it here
so that we do not depend on that for future usages.

This patch adds a basic framework for creating I/O channels
for I/O devices. An spdk_io_channel represents a one-to-one
mapping between a calling thread (represented by spdk_thread)
and an I/O device that the thread will perform I/O operations
on.
