There were several applications that were missing
either SOCK_MODULES_LINKER_ARGS or COPY_MODULES_LINKER_ARGS.
For the ones missing SOCK_MODULES_LINKER_ARGS (fuse and rocksdb),
the nvme inititator with TCP transport would not have worked
at all.
Adding COPY_MODULES_LINKER_ARGS to the bdev fio plugin enables
ioat which isn't critical, but adding it makes it consistent
with other apps and will allow its Makefile to be simplified in

blob and blob_bdev are already included via the lvol bdev module
dependencies in mk/spdk.modules.mk. This patch adds blobfs there
too.
These changes are needed for some upcoming patches which will
apply --whole-archive to all libraries linked into the application.
That patch will require that we never include the same library
twice.
Shared library builds *require* that blobfs be listed before
blob on the link line, hence adding blobfs here even though it's
not technically associated with a bdev module.
We can also simplify spdk.modules.mk while we're here - just
filter out bdev_lvol to disable lvol for applications like
blob_cli that need to disable it.

RPC is core functionality for SPDK applications and should always

So make RPC a first class citizen and integrate it with the

Then we initializing it after all subsystems have completed
initialization, and tear it down before tearing down subsystems.
We can also do some other cleanup while here - for example, reactors
are already started when spdk_rpc_initialize() is called, so remove
the extra event that was added during initialization since this is no
