19100ed580 bdev: rename spdk_bdev_module_if -> spdk_bdev_module

No functional change - this is a pure find/replace of

4d36735401 bdev: rework bdev module registration
Currently SPDK_BDEV_MODULE_REGISTER() take many parameters. Extending it
(eg for incoming JSON configuration dump/load) is quite challenging and
error prone. As we are already here in next patches, rework this macro
to take one parameter - the pointer to struct spdk_bdev_module_if.

This patch also remove following macros:
SPDK_GET_BDEV_MODULE - this is not really needed, to find module outside
module translation unit use spdk_bdev_module_list_find()

SPDK_BDEV_MODULE_ASYNC_INIT and SPDK_BDEV_MODULE_ASYNC_FINI - replaced
by bool fields in spdk_bdev_module_if struct.

between NVMe SSDs using Controller Memory Buffers (CMBs) that support
DMA operations. Add documentation for the API, the example application
(cmb_copy) and for P2P setup and operation.

Note that this new API is currently marked experimental.

cb5178ea40 lvol: set default cluster size to 4MiB
Blobstore default cluster size is currently 4MiB,
but default lvol cluster size overrides it to 1GiB.

Additionally add -c flag in lvol tests to set cluster
size for tests.

1GiB was fine without thin provisioning, but we do not
want to allocate and copy 1GiB of data for newly allocated
clusters on thin provisioned logical volumes.

Note that 4MiB is same as default for Linux LVM.

lvol test case 601 had to be modified to create a malloc
LUN less than size of default cluster size.  This test is
supposed to fail - without the change here, creating the
lvolstore would work, but the script still considered it a
PASS.  Defer fixing that to a separate patch - for now just
keep the same test process.

0eff26b3c7 doc/getting_started: mention setup.sh help
The help message was introduced in patch
5f247660d7 [1].

[1] 5f247660d7 ("setup.sh: add help message")

While here, also removed "Make sure you aren't using an NVMe
device as your boot device." note. This is no longer the case,
as we're now checking for active mountpoints before unbinding
NVMe devices.

4609215690 doc/nvmf: clean up and reorder the nvmf_tgt docs
- Remove outdated section about pre-release kernels; the Linux kernel
  support has been in released kernels for a while now.
- Switch to ./configure rather than `make CONFIG_...`.
- Put the target configuration into subsections, and move it earlier in
  the doc.
- Clean up some wording and style issues.

40c911b957 blob: add used blobid bit array for valid blobids
This can be used for two purposes:

1) more quickly iterate the blob list, avoiding
   metadata pages that are valid but not the first
   page in the blob's metadata list
2) close races between delete and open operations -
   now we can clear the bit in the blobid bit array
   when the delete operation is in progress, ensuring
   no one else can try to open the blob
