This fixes the new nvmf_subsystem_add_listener RPC method to use "nqn"
as the parameter name to be consistent with the other NVMe-oF target RPC
methods.

Since this method is brand new, no provision for compatibility with the
old name is provided.

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.

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

d12ba75bd1 blob: add per-blob feature flags
Similar flags will be added at the blobstore level in a future
patch.

This allows backwards compatibility - i.e. allow older blobstore
applications to open blobstores created by newer blobstore
applications with new features.  Any blob's using a new feature
should have an associated flag set in one of three new flag masks:

- invalid: if a bit is set in this mask that the application is not
	   aware of, do not allow the blob to be opened
- data_ro: if a bit is set in this mask that the application is not
	   aware of, allow the blob to be opened, but do not allow
	   write I/O nor any operation that changes metadata
- md_ro:   if a bit is set in this mask that the application is not
	   aware of, allow the blob to be opened for performing any
	   kind of I/O, but do not allow any operation that changes
	   metadata

While here, bump SPDK_BS_VERSION to 3.  We intend this to be the
last change made to SPDK_BS_VERSION - future versioning will be
done via blobstore or per-blob feature flags instead.
