In spdk_fio_report_zones(), log_err did not prefix messages with
"spdk/nvme", making it hard to determine who dumped the error-message.
In spdk_fio_reset_wp() log_err described the wrong function.
This change fixes the above.

When _reset_wp() received a range to reset, then the loop kept resetting
the first zone in the range.
Also, the processing of command-completion were re-using the same
'completion' state, thus a previous completion would short-circuit
command-completion such that it would never be processed.
This change fixes that.
Also, the reset-loop assumes that the given offset is a valid zone-start
LBA, a check is added to verify that and return -EINVAL if it is not.

When a device has resource-limitations such as the
maximum-open-resources (mor) and this threshold is exceeded, then IO
will fail upon completion. Such behavior is not the most user-friendly
way to tell the user that they should provide a value for the
fio-parameter 'max_open_zones'.
This change provides an arguably more user-friendly approach by checking
whether the device is limited and in case it is:
* Provide a default value for 'max_open_zones', inform the user, and
continue
* Verify 'max_open_zones' and in case of error inform the user and
return error

If the user decided to disable ICD then we have several side effects:
1. SPDK prints several warnings/errors
2. SPDK doesn't create recv pipe and doesn't set SO_RCVBUF socket option.
I think that we should not rely on ICD only when we create recv pipe or
set SO_RCVBUF since data may be transferred in sgls via R2T/H2C and
we still need recv_pipe and SO_RCVBUF for better performance.
Alternative option is to set recv_buf_size as a maximum between
ICD and io_unit_size

According to the SPEC we should support up to 8192 bytes
of ICD for admin and fabric commands. Transport configuration
parameter in_capsule_data_size is applied to all qpair types -
admin and IO. Also we allocate resources when we get a connection
request, so we don't know qpair type at this moment.
Create a list of buffer in TCP poll group to support ICD up
to 8192 bytes when configuration ICD is less than this value.
The number of elements in this pool is hardcoded, it is planned
to add a new configuration parameter later.

In TCP NVME initiator with zero copy enabled requests might be
completed asynchronously - out of qpair_process_completions
context. At the same time we calculate requests completed
asynchronously so that generic NVME layer can resubmit
queued requests after calling qpair_process_requests (or
poll_group_process_requests).
But there is a time gap between async request complete and
qpair_process_completions and the user can submit new IO
thereby decrease the number of free TCP requests. That means
that there might be less free requests than we excpected when
we try to resubmit queued requests.
The solution is change ERRLOG to DEBUG log since it is not a
fatal case.

If interrupt is set, related poller functions will be
registered to thread interrupt instead of poller.
interrupt_tgt can create aio bdev now.

interrupt_tgt is similar with vhost_tgt, but it is constructed by
libaries supporting event interrupt mode with interrupt functions.
Some basic bdev libraries are linked in it.
"interrupt_tgt -E" will run the app in interrupt mode.
At start, it can work with SPDK RPC methods.

Each reactor and each thread is assigned with one fd group.
At the same time, each thread is treated as one interrupt source
registered into its corresponding reactor.
The egrp function for reacotr is the only block point waiting
for events.

Interrupt is aiming to support interrupt
mode in SPDK application framework.
fd_group is implemented by epoll on linux.
fd_group can be inserted into thread and reactor
to do epoll_wait internally in order to avoid polling
