This prepares for upcoming patches which handle -ENOMEM
from the SPDK bdev io submit function. When we retry
submitting the I/O, we do not want to "re-prepare" the
I/O - i.e. we don't want to calculate a new offset or
memset the buffer again for verify workloads.

Several apps link against $(COPY_MODULES_LINKER_ARGS) without adding
$(COPY_MODULES_FILES) to the dependency list. This means that those
apps would not get rebuilt if the copy modules were modified without a
'make clean'.
The blobfs example apps were also missing other dependencies; add those
while we're here.

This patch changes the default setting of IOAT copy engine from
Enabled to Disabled. Accordingly this patch changes the config file
specification for IOAT copy engine from "Disable Yes/No" to
"Enable No/Yes".
Subsequent patches will add a new JSON RPC to configure IOAT
copy engine dynamically.

While here, don't print out empty performance data if the
test run failed (for example, if no bdevs were found). Also
remove superfluous "done" message at the end of main - it
really serves no purpose and looks silly especially if the
test failed.

There is an existing unmap "workload" but it is not a
real workload - it's just used as a type of verify
function to check if an unmapped region later returns
zeroes. This has typically been true for Intel NVMe SSDs
but is not universal, so this functionality is not really
useful. It's not used anywhere in any of the tests in the
SPDK tree either.
So replace it with a real "unmap" workload that will
do sequential unmap operations on the underlying
bdev. A future enhancement could make these unmap
operations random across the bdev - but that can be
added later.

This commit adds a simple hello world example that writes the string
"Hello World!" to a bdev. The example can be used on a block device
such as Malloc or virtual bdev such as the passthru vbdev. The
sample bdev.conf configuration file includes a configuration for 2
malloc bdevs and one passthru bdev on top of Malloc0.
