5b16c18d17 build: move app rules to spdk.app.mk
This removes a ton of duplicate from a lot of
Makefiles.  Note that spdk.unittest.mk still keeps
its own app rules, and now just includes
spdk.app_vars.mk instead.  Fixing Makefiles that
include this .mk file requires more work that is
deferred for now.  We do need to add the
"install: all" rule explicitly to this .mk files.

Note that Makefiles need to include spdk.app.mk
now at the end of the file, so that things like
APP and SPDK_LIB_LIST are defined before including
it.

5704be8987 build: remove xx_MODULES_LINKER_ARGS and xx_MODULES_FILES
Application Makefiles can now just add xx_MODULES_LIB_LIST
to SPDK_LIB_LIST.  This is possible now since all
SPDK libraries are linked with --whole-archive, so there
is no need to differentiate between "modules" libraries
and other SPDK libraries.

6005fdba84 build: add missing xx_MODULES_LINKER_ARGS
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
some future patches.

3da5847023 build: add ENV_LINKER_ARGS to LINK_C and LINK_CXX
This allows us to remove $(ENV_LINKER_ARGS) from all of the
application Makefiles.

Modify spdk.unittest.mk to explicitly set ENV_LINKER_ARGS
to nothing, to avoid DPDK libraries from getting linked
into unit tests.  This seems better than creating separate
LINK_C rules for unit tests.  Provide a UNIT_TEST_LINK_ENV
flag to allow select unit tests to override this behavior -
it's needed for some of the env unit tests.

0b5fa082db build: remove sock from SOCK_MODULES_LIST
The various *_MODULES_LIST are intended for the modules
that implement the specific interface - not for the
associated core library itself.

For example, BLOCKDEV_MODULES_LIST doesn't contain bdev,
it contains all of the bdev modules.  Similar for
COPY_MODULES_LIST and copy.

So make SOCK_MODULES_LIST consistent.  This is a real
pain because we have to add sock explicitly to a bunch
of individual Makefiles, but I have plans to clean that
up in some future patches.

Fio commit d3b07186b1d4c7c1d9adc1306407458ce41ad048 changed return
type of the ioengine->queue method to a new enumeration type
fio_q_status. Add preprocessor checks to ensure SPDK fio_plugin builds
successfully with both current and earlier fio ioengine API version.

With this change, rebuilding SPDK after no changes
will result in no output - all of the "Nothing to
be done for 'all'" messages have been removed.  Note
that DPDK build output still remains - this can be
suppressed by either using an out-of-tree DPDK, or
using SKIP_DPDK_BUILD=1 when using the in-tree DPDK

6c54c13cd4 event/subsystem/bdev: asynchronous SPDK finish
First this change moves spdk_subsystem_fini() to trigger on
spdk_app_stop(). This ensures that spdk_subsystem_fini() is called
before reactors are stopped in spdk_reactors_stop().

Finish paths for subsystems, bdevs and copy engine is now
asynchronous.
Each of those three mentioned have to make sure they are
asynchronous as well.

Only bdev that currently has requirement for asynchronous finish
are logical volume.
Thus the change in vbdev_lvol.c making it move to next bdev module
only after all lvol stores were unloaded.

Fio_plugin finish of bdev and copy_engine was removed for now.
Next patch in series adds it back with async support.

Always start bdev pollers on the calling core.

This removes the lcore concept from the bdev poller abstraction and
simplifies the job of spdk_bdev_initialize() callers providing their own
poller and event implementations.

All callers except the NVMe bdev hotplug poller already used the current
core as the parameter.  The NVMe HotplugPollCore option was undocumented
and unused in any of the tests or example configuration files, so it
should be safe to remove.
