Currently run count of poller has been incremented per execution.
It will be helpful for us to know how poller is busy by adding busy
count which is incremented only when some work is done.
spdk_thread_poll() has used the same timestamp in it, and so this is
the maximum we can do for now.

Extract _spdk_thread_exit() from spdk_thread_exit() and
_spdk_thread_poll() calls _spdk_thread_exit() if the thread is in
the exiting state. spdk_thread_exit() changes to move the state to
the exiting state. The spdk_thread_poll() loop will end after the
thread moves to the exited state because the caller of
spdk_thread_poll() will check if the thread is in the exited state,
and break the loop if true.
If the user does not call spdk_thread_exit() explicitly, the reactor
has to terminate all existing threads at its shutdown. In this case,
multiple threads may have some dependency to release I/O channels or
unregister pollers. So the reactor has the large two loops, the first
loop calls spdk_thread_exit() on all threads, the second loop calls
spdk_thread_destroy() if exited or spdk_thread_poll() otherwise for
each thread until all threads are destroyed.
Besides, change the return value of spdk_thread_exit() to return
always 0. Keep it for ABI compatibility. Change ERRLOG to INFOLOG
for _spdk_thread_exit() because it is called repeatedly now. Remove
the check of I/O reference count from _spdk_thread_exit() because
_free_thread() cannot free I/O channel. Refine the unit test
accordingly.

We have been intermittently hitting the assert where
we check sock->cb_fn != NULL in spdk_sock_group_impl_poll_count.
The only way we could be hitting this specific error is if we
wereremoving a socket from a sock group within after receiving
an event for it.
Specifically, we are seeing this error on the NVMe-oF TCP target
which relies on posix sockets using epoll.
The man page for epoll states the following:
If you use an event cache or store all the file descriptors
returned from epoll_wait(2), then make sure to provide
a way to mark its closure dynamically (i.e., caused by
a previous event's processing). Suppose you receive 100 events
from epoll_wait(2), and in event #47 a condition causes event
#13 to be closed. If you remove the structure and close(2)
the file descriptor for event #13, then your event cache might
still say there are events waiting for that file descriptor
causing confusion.
One solution for this is to call, during the processing
of event 47, epoll_ctl(EPOLL_CTL_DEL) to delete file
descriptor 13 and close(2), then mark its associated data
structure as removed and link it to a cleanup list. If
you find another event for file descriptor 13 in your batch
processing, you will discover the file descriptor had
been previously removed and there will be no confusion.
Since we do store all of the file descriptors returned from
epoll_wait, we need to implement the tracking mentioned above.

Update spdk_thread_poll() to count SPDK thread stats correctly on multiple
SPDK threads per reactor configuration.
spdk_thread_poll() gets start time and reads TSC at end as end time,
and then gets delta between them as run time. Run time is added to idle
time or busy time according to the result of polling.
Reactor overhead is included into the next thread which calls
spdk_thread_poll() now.
spdk_thread_poll() saves the end time to the current thread to use it
as the start time of the next thread.
Unit test framework for this patch and the next patch need to access
thread->tsc_last. In the next patch, reactor will use the end time of
the current thread to the start time of the next thread in reactor_run()
to realize the idea.
Hence add an new API spdk_thread_get_last_tsc(). The corresponding
variable is named as tsc_last and it is good and is aligned with
DPDK (DPDK has used tsc_start and tsc_end as variable name). But
last_tsc will be better as API name because the last TSC value is
easier to understand.
Then add necessary unit test and update the unit test framework.

The revert asynchronous API doesn't run as the *real* asynchronous
way, because the drive can only support synchronous module and only

RPC call has the default timeout value here, while the revert may
take over several minutes, the API itself doesn't short the revert
action, so just remove it and use the synchronous API instead.
The revert action will erase all the users data and bring the drive
back to the factory state, it should run in the synchronous mode,
so just remove the asynchronous API and we can increase the timeout
value when using RPC to call this API.

spdk_nvmf_poll_group_destroy() sets the passed callback to the passed

In the next patch a new transport call will be added to notify
transports of subsystem->listener associations. The operations the
transports may need to perform there are likely asynchronous, so make
this top level call asynchronous here in preparation.

3rd party library can be integrated with spdk code. To simplify that
integration nvme status filed within that patch is exposed as union
with u16. Having that is easier to assign spdk status when rhs is u16
and easier to read when lhs is u16. However, both sides need to be
aligned with nvme spec.
To align with SPDK style it shall be rather status.bits / status.raw
but it requires a lot of changes in nvme/nvmf library.
Note: According to spec phase tag is not within status but Linux
driver does similar, when rsp needs to be set it just shift left 1.

Add an new JSON RPC thread_get_pollers to retrieve pollers of all
the threads. By adding a helper function spdk_poller_state_str(),
output poller state as string to improve readability. Most of the
code of thread_get_stats and thread_get_pollers are common and so
unify these two RPCs as possible as we can.
Sample output of thread_get_stats RPC in doc/jsonrpc.md was wrong
because thread_get_stats doesn't output ticks. Fix this together.

This was recently made asynchronous to support virtualized transports.
However, we're moving to add a new call to associated a listener with a
subsystem to transports and the operation that needed to be asynchronous
will actually be performed there. For simplicity, make this synchronous
again.

New spdk_ftl_conf parameter l2p_path, l2p_path defines
location of existing pmem file or device to use as l2p table.
ftl_dev_l2p_alloc now has two flows:
1. If l2p_path is set perform pmem_map_file (PMDK) of l2p_size on it
2. Else malloc l2p table as usual
l2p_get/set will use atomic_load/store on both of those storage
locations as PMDK pmem_memcpy family of functions is not thread safe.

Add an new API spdk_poller_register_named() to set arbitrary name
to the created poller. If NULL, the name is set to the pointer of
the poller function.
To set the name to the string of the poller function name conveniently,
add an new macro SPDK_POLLER_REGISTER() together in this patch.
All debug or error logs are changed to output poller name from pointer.
The added name will be used in the new RPC thread_get_pollers.
