In current implementation, io_channel list will be accessed by
spdk_for_each_channel() and spdk_get_io_channel(). We will try to
accelerate spdk_get_io_channel() in the following change "thread: speed
up io_channel lookup by using rbtree" by changing io_channel from list
into RB tree.
To make it cleaner, we prefer to use ch->dev as the key for the
io_channel RB tree instead of ch->dev->io_device. This patch makes
spdk_for_each_channel() use the i->dev to find the expected io_channel.
And the io_device in structure spdk_io_channel_iter is not needed in
spdk_for_each_channel_continue() but we keep it for the compatibility of
spdk_io_channel_iter_get_io_device().
After this patch, spdk_for_each_channel() has to access both io_device
list and io_channel list, and spdk_for_each_channel_continue() still has
to access only io_channel list.
Both io_device list and io_channel list will become RB tree. Hence
performance degradation will be negligible. spdk_for_each_channel() is
not so performance critical than spdk_get_io_channel().

Check the return code of RB_INSERT() because this is the first use case

When a timed poller is inserted, update the cache for the closest (leftmost)

If spdk_poller_pause() and spdk_poller_resume() are called while poller

poll mode and interrupt mode with dynamic switching.
spdk_interrupt_mode_is_enabled() indicate whether interrupt
mode is enabled and dynamic switching is permitted. So
spdk_interrupt_mode_is_enabled==true leads to set up
interrupt mode related resources;
in_interrupt flag indicates whether one spdk_thread now

It is possible that spdk_interrupt_mode_is_enabled==true

switched to poll mode from interrupt mode due to heavy
workload coming.
To align with spdk_reactor, use "in_interrupt" to
indicate whether one spdk_thread now runs in intr.

Since spdk_thread_poll will set/restore tls_thread,
there is no need to set or restore it again here.

To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.
Increasing major so version after LTS, allows the quarterly releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.
Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 21.04
release.
This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests

Current SPDK thread library has a issue which occurs if there is
a race between exiting thread and unregistering io_device.
For example, there are two threads. Thread 1 registers a device
and thread 2 gets a channel of the device. Then if thread 1 starts
exiting and unregisters the device, and then thread 2 puts the channel,
thread 2 sends a message to thread 1 to complete releasing the device,
thread 1 already moved exited. Hence thread 2 failed to send the
message.
This patch fixes the race issue. The code is verified by adding
a unit test case.
In detail, add a count, unregistering_dev, to struct spdk_thread,
increment it if a callback is specified to spdk_io_device_unregister(),
and then decrement it in _finish_unregister(), and thread_exit()
checks if it is zero.
The contents of struct spdk_thread is changed but it is not public
data structure, and hence suppress it for ABI testing.
