One of stop conditions in data WR release function was wrong. This
can cause release of uncompleted data WRs. Release of WRs that are
not yet completed leads to different side-effects, up to data
corruption.
The issue was introduced with send WR batching feature in commit
9d63933b7f4cd3b279b2b481ed452c64c226dcd3.
This patch fixes stop condition and contains some refactoring to
simplify WR release function.

Purpose: Reduce the recv/readv system call.
Method: Use a big recv buffer to conduct the read.
Though it will introduce addtional buffer copy,
we hope that the overhead introduced by buffer copy will
be smaller compared with frequent recv/readv system call overhead.
And the design is to make a trade off between them.

Originally loading json_config using spdk_app_json_config_load_subsystem()
implied issuing start_subsystem_init RPC. This required a workaround
in the callback of RPC spdk_rpc_start_subsystem_init_cpl(), in order
to skip starting the app in json_config load path.
This made it difficult to load json_config without implicitly using
rest of the event framework. It will be usefull for example in
fio_plugin, which does not use the app.c API.
With change in this patch json_config load path directly calls
spdk_subsystem_init() C call.
Meanwhile start_subsystem_init RPC no longer needs a workaround
for json_config load path.

We've recently switched from manually calling eventfd_write()
to rte_vhost_vring_call(), which besides writing to the
eventfd, always calls a full memory barrier in the upstream
rte_vhost lib. With upstream rte_vhost we're actually
calling two memory barriers on I/O completion - one in
spdk code, one inside rte_vhost_vring_call().
The spdk barrier was only required for our internal rte_vhost
lib, whose rte_vhost_vring_call() implementation (that we
wrote) did not have such membarrier inside. So now we'll
add this membarrier there, and remove the same barrier
from spdk code.
This doesn't change any code flow for the internal rte_vhost
lib, but optimizes I/O path for the upstream version.

These directories fit in with the module concept we are forming inside
of SPDK. Essentially modules are derivative or specialized libraries that
rely on a general or core library.

This is more accurate to what they are, and will make defining library
dependencies much simpler. This change in directory does not affect the
final placement of naming of libraries at the end of time.

Expose spdk_app_json_config_load() in internal to SPDK header.
In future patches it will be possible to use this function
without depending on rest of event framework (such as app.c).
Applications that do not use SPDK reactors (have their own threading
model) or no need to initialize using spdk_app_start(), will be
able to utilize subsystems and their json configuration loading.

The previous patch in this series introduced the notion of an
orphan comp bdev which is available only for deletion due to
a missing PMEM file. This RPC allows applications to list
orphaned comp bdevs as they will not show up with get_bdevs
because they are not registered bdevs.

When a vol load fails because of a missing pmem file, instead of
doing nothing we now claim the underlying bdev and make an entry
in our global list for a comp bdev so that the regular delete
RPC can be used to delete the comp bdev.
