In the following patches, we will add a feature to inject data
corruption to the error bdev module. For read I/O, we will have
to inject data corruption at completion. However, if we use
spdk_bdev_part_submit_request(), it will not be possible because we
cannot add any custom operation into the completion callback.
To fix the issue, modify spdk_+bdev_part_submit_request() and
rename it to spdk_bdev_part_submit_request_ext().
Fortunately, we can use stored_user_cb in struct spdk_bdev_io.

To support SQs allocated to a poll group other than the controller's
main poll group, we need to make sure to poll those SQs when we wake up
and handle the controller interrupt. As they will be running in a
separate SPDK thread, we will arrange for all poll groups to wake up
when we receive an interrupt corresponding to a vfio-user message
arriving.
This can mean needless wakeups: we don't (yet) have a mechanism to only
wake up the poll groups that correspond to a particular SQ write.
Additionally, as we don't have any notion of a poll group per
controller, this ends up polling all SQs in the entire poll group, not
just the ones corresponding to the controller we were handling.
As this has potential performance issues in many cases, it defaults to
disabled.

In a use case, a custom sock module supports zero copy for read.
The custom sock module wants to keep the recv_buf_size to be sufficiently
large, for example 16MB. However, most upper layers overwrite the recv_buf_size
by a smaller value via spdk_sock_set_recvbuf() later. This is not desirable.
To fix the described issue, change the meaning of impl_opts->recv_buf_size
to be the minimum size, and spdk_sock_set_recvbuf() uses the maximum value
among the requested size, g_spdk_sock_impl_opts->recv_buf_size, and
MIN_SO_RCVBUF_SIZE.
We may have to change the code to initially create a socket. However,
for most cases, the upper layer calls spdk_sock_set_recvbuf() anyway.
Hence this fix will be minimal and enough.
For the use case, it is enough to change recv_buf_size of the posix sock
module. However, the custom sock module may support I/O uring in future.
Hence, change I/O uring sock module together.
Additionally, for consistency, change the meaning of impl_opts->send_buf_size
to be the minimum size, and spdk_sock_set_sendbuf() uses the maximum value
among the requested size, g_spdk_sock_impl_opts->send_buf_size, and
MIN_SO_SNDBUF_SIZE.

By doing the registration immediately upon mapping the BAR instead of
when the memory is inserted into the spdk_mem_map, we're able to
register BARs that are not 2MB multiples in size and alignment. The SPDK
API for registering a BAR already returns the physical/io address in the
map call, and it can be used directly without a call to
spdk_mem_register().
If the user does elect to later register the BAR using
spdk_mem_register(), we attempt to insert the 2MB aligned segments we
can into the spdk_mem_map. Users may still need to register memory for a
few reasons, such as making spdk_vtophys() work, or for setting up the
BAR as a target for RDMA. These cases still require 2MB aligned and
sized segments.

Previously we would always allocate the shm file based on
max (128) cores which is unnecessary. So use
spdk_env APIs to only allocate shm file size based
on the cores we might possible use.
With default settings, an shm file was 135MB before this
change, now an app using cores 0-7 will just use
about 9MB.
A lot of the trace-related code depended on there
*always* being a history for every core, even unused
ones, so a few additional changes were needed,
mainly the trace_parser library.
Tested by starting an app using a 0x4 core mask and
enabling a trace mask, generating some events, then
checking both the size of the shm file and that
spdk_trace works properly with the resulting file.

Some use cases want to abort every bdev_io submitted to the bdev by
traversing the bdev channels.
However, struct spdk_bdev_channel is private in lib/bdev/bdev.c.
Hence, add a helper function spdk_bdev_for_each_bdev_io() to execute
the function on the appropriate thread for every bdev_io submitted
to the bdev.
This function should be used only from the bdev module and it should
be ensured that the bdev is not unregistered during execution.
We keep this function as generic as possible because we may have
other use cases in future.

The word engine was both used (interchangeably with module) to refer to
the things that plug into the framework and to the framework itself.
This patch eliminates all use of the word engine that meant the
framework. It leaves uses of the word that meant "module".

Writing to unallocated cluster triggers copy-on-write sequence. If
this cluster is backed by zeroes device we can skip the copy part. For
a simple thin provisioned volume copy this shortcut is already
implemented because `blob->parent_id == SPDK_BLOBID_INVALID`. But this
will not work for thin provisioned volumes created from snapshot. In
this case we need to traverse the whole stack of underlying
`spdk_bs_dev` devices for specific cluster to check if it is zeroes
backed.
This patch adds `is_zeroes` operation to `spdk_bs_dev`. For zeroes
device it always returns 'true', for real bdev (`blob_bs_dev`) always
returns false, for another layer of `blob_bs_dev` does lba conversion
and forwards to backing device.
In blobstore's cluster copy flow we check if cluster is backed by
zeroes device and skip copy part if it is.

2.json content that 'subsystems' not associate with array, it will report error and return failure, e.g.
{"subsystems":"123"}
3.handle other invalid json formats, report and return failure, e.g. duplicate keys.
Added `spdk_json_find` API return errcode: EPROTOTYPE - json not enclosed in {}.
json config with content:
1."not enclosed in {}"
2."'subsystems' not be an array"
3."duplicate key in json"
and some other invaild cases will be regarded as invalid json config, and will fail to start app.
