If the bdev is a zoned bdev, reset zone 0 (containing offset 0),
before doing the "Hello world!" write to offset 0.
This is done to ensure that the write pointer for the first zone
is at offset 0.
If we don't do a zone reset before doing the write, the write
would fail if there already were data written to the first zone.
(E.g. if the user ran the hello_bdev example twice.)

All of our Makefiles duplicate huge lists of libraries
in SPDK_LIB_LIST. We have a very precise and accurate
accounting of the library dependencies in
mk/spdk.lib_deps.mk which can be used to generate
the full list if the app specifies the modules and
subsystem libraries it wishes to link.
I did a first pass through all of the existing
Makefiles to take advantage of this new functionality.
There may be more optimizations we can make later but
don't want to hold up this patch for all of them.

to allow the message passing to all complete, so this behavior in fio

place that thread onto a global list that's polled by the init thread
which lives for the duration of the program. The init thread will
continue polling the spdk_thread until it has exited.

--filename="$(discover_bdevs /path/to/spdk.json --json)"
The bdev names are usually hardcoded in the json config, but still,
they have to be provided to fio again. Not anymore - just use
--filename=* and FIO will use all available bdevs as I/O targets,
just as if all filenames were provided.
The above command could be now simplified to:
fio_bdev /path/to/job.fio --spdk_json_conf=/path/to/spdk.json --filename=*

This is fix for https://github.com/spdk/spdk/issues/523
Fio hangs on pthread_exit(NULL) from spdk thread.
This happens because, pthread_exit tries to dlopen glibc and hangs on
__lll_lock_wait. This patch prevents unmapping of glibc in fio_plugin
and phtread_exit does not need to dlopen it again.

This name more closely resembles pthread_exit, which is a
closer analogy to how the new threading library works.

own threads.
