Moving data from one band to the other doesn't need to be stored on the
non-volatile cache. Not only does it add unnecessary traffic to the
cache (wearing it out and reducing its throughput), but it requires us
to synchronize it with user writes to the same LBAs.
To avoid all that, this patch adds the FTL_IO_BYPASS_CACHE flag to all
writes coming from the reloc module. However, to be sure that the moved
data is stored on disk and can be restored in case of power loss, we
need to make sure that each free band have all of its data moved to a
closed band before it can be erased. It's done by keeping track of the
number of outstanding IOs moving data from particular band
(num_reloc_blocks), as well as the number of open bands that contains
data from this band (num_reloc_bands). Only when both of these are at
zero and the band has zero valid blocks it can be erased.

When using stacked virtual bdev (e.g. split virtual bdev), block
address space will be remapped during I/O processing and so reference
tag will have to be remapped accordingly.
The use case is explained in detail as follows:
- Format a single NVMe SSD with DIF enabled.
- Create a NVMe bdev on the NVMe SSD with DIF enabled.
- Create four split vbdevs on the NVMe bdev.
- Add the split vbdevs to a NVMe-oF target.
- Application is aware of block address space of the split vbdevs.
- Application submits read/write I/O to the NVMe-oF target.
Case 1:
- Configure NVMe-oF target to DIF pass-through.
Case 2:
- Configure NVMe-oF target to DIF insert/strip
For the case 1,
- Application inserts DIF for write I/O and verifies DIF for read I/O.
- The split vbdevs remaps reference tags of DIF both for read and write
I/O because application expects reference tags are based on the
block address space of split vbdevs.
- The NVMe bdev processs read/write I/Os without remapping reference tags
because reference tags are already based on the block address space
of the NVMe bdev.
For the case 2,
- NVMe-oF target inserts DIF for write I/O, and verifies and strips
DIF or read I/O.
- The split vbdevs remaps reference tags of DIF both for read and write
I/O because NVMe-oF target expects reference tags are based on the
block address space of split vbdevs.
- The NVMe bdev processs read/write I/Os without remapping reference tags
because reference tags are already based on the block address space
of the NVMe bdev.
This patch adds two APIs, spdk_dif_ctx_set_remapped_init_ref_tag
and spdk_dif_remap_ref_tag to satisfy the use case.
UT code is added together in this patch.

Length of xattr descriptor is equal to length of xattr struct,
xattr name and the len of stored value.
There is no limit to how much can be stored in memory for xattr.
On disk xattr size is limited to single page and within that to
max descriptors that can fit in it.
This size is known at compile time.
Before this patch it was possible to add xattr exceeding
what was possible to be written to disk. This caused issues
when serializing the metadata during spdk_blob_sync_md()
or spdk_blob_close(). Making those fail without specific info
to the user and not actually writting such descriptor.
Since maximum length of xattr descriptor is known at compile time,
this patch compares against this value when setting the xattr.
It will immediately report back to user with error, and will
not store xattr in memory (thus not serialize it).
This patch should not affect any backward compatibility for blobs.
Too large xattrs weren't written to disk before,
API for blobstore stays the same - only reporting ENOMEM
when it should.

When the NVMf controller's flag dif_insert_or_strip is enabled, DIF is
inserted for write I/O and stripped for read I/O, and the corresponding
NVMe-oF initiator should not be aware of the DIF setting of the
backend bdev.
Hence this patch hides the DIF setting of the backend bdev
when the flag dif_insert_or_strip is enabled.

calling spdk_nvmf_request_get_dif_ctx().
But NVMf controller knows if DIF/insert/strip is enabled now by the

controller enables DIF insert/strip at its head.

We replace spdk_vhost_allocate_reactor() with
spdk_vhost_get_poll_group(). The returned poll_group
has to be passed to spdk_vhost_session_send_event(),
where it will be assigned to the session. After the
session it started, that poll group will be used for
all the internal vhost cross-thread messaging.

Here is the an example to describe existing issue:
There is a Write request with 64KiB data length, and this IO is cross the IO
boundary. We assume that the parent IO will have 2 children requests, one is
33KiB length, the other one is 31KiB. Here is the view of parent iovs, the
first 33KiB length data has 33 iovs:
iov.[0].iov_length = 1024;
.
.
iov.[31].iov_length = 256;
iov.[32].iov_length = 768;
.
.
iov.[64].iov_length = 1024;
In function _spdk_bdev_io_split(), then you can see that for the 33KiB length
child request, exiting code will run out of child child_iov space and return
error due to last one data buffer is not block size aligned.
Here we can rewind the existing offset to last block size aligned buffer to
avoid the error case, for backend which need aligned data buffer such as
AIO backend, the request will go through spdk_bdev_io_get_buf() again to
do the data copy, otherwise for those backend devices such as NVMe with
hardware SGL support, 256 data segment is fine for them.

In case ANM event occurs on open band there
can be situation that reloc will try to read
block on which there is ongoing write.
This is happening because lba valid map is
updated before write submission to allow sent
consistent metadata to disk before all user
writes are completed.
Added write offset to the each chunk and
add check to reloc if particular ppa is written
on that chunk.
