When we introduce red black tree for timed pollers, we will not use
RB_FOREACH_SAFE() but cache the leftmost (smallest) node and iterate
from it via RB_NEXT() instead.
As another preparation, separate TAILQ_FOREACH_SAFE() into TAILQ_FIRST()
and TAILQ_NEXT().
The next patch will cache the first element to thread and refer it
first.

It will be sufficiently reasonable to check if the caller thread is valid
even if spdk_poller_pause() or spdk_poller_resume() does nothing.
Besides, let's write all possibles states explicitly in switch - cases.
This refactoring clarifies the logic and makes the following patches easier.

The following patches will introduce red black tree to manage
timed pollers efficiently but it will be based on macros available only
in lib/thread/thread.c. Hence then it will be difficult to expose the
internal of timed pollers tree outside the file. On the other hand,
we do not want to include JSON into the file.
Hence add a few SPDK internal APIs to iterate pollers list transparently.
For spdk_thread_get_next_active/timed/pause_poller(), we omit the parameter
thread and get it internally from poller->thread even if the names include
the term "thread". This will be slightly cleaner.

(Note: this patch was previously applied as b32cfc46 and then reverted
as 63642bef.)
Today the in-guest nvme device shows physical_block_size=512 even though
the backend iSCSI bdev supports physical_block_size=4K
iSCSI targets exposes physical block size using
logical_block_per_physical_block_exponent in READ_CAPACITY_16
NPWG is one of the way to let Linux nvme driver set
physical_block_size of the nvme block device.
This patch adds spdk_bdev.phys_blocklen which is updated if the iSCSI
backend exposes physical_block_size.
Later phys_blocklen is used in nvmf to set NPWG and NAWUPF to report
back during NS identity.
Linux driver uses min(nawupf, npwg) to set physical_block_size.
Similarly in scsi_bdev fill lbppbe in READ_CAP16 response
based on spdk_bdev.phys_blocklen.

1) use spdk_bdev_get_name() accessor
2) use __SPDK_BDEV_MODULE_ONLY #define
The latter allows nvmf to just get the spdk_bdev_module
definitions and APIs that it needs for claiming bdevs
for purposes of avoiding the same namespace used in
different subsystems.
This also ensures that future changes to structures
like spdk_bdev and spdk_bdev_io will not cause
lib/nvmf so version changes.
Note: we include bdev_module.h explicitly in the
nvmf/subsystem unit tests now, before including
subsystem.c, because the unit tests do depend on
knowing the internal structure of spdk_bdev.

libvfio-user DMA APIs report all regions notified by the client, including those
that don't have a corresponding shared mapping. There are several of these for
a typical VM, so just ignore this case.
