d132ee3531 build: use DEPDIRS variables to build SPDK_LIB_LIST
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.

This change will make sure that ioat_perf application

9018dd60c6 examples: rename ioat perf tool to ioat_perf
This avoids conflict with the nvme perf tool.  PGO
gets confused during building - we may have data for
nvme/perf which it then tries to use when building
ioat/perf.  Renaming the ioat perf tool fixes that
problem.

5ec6b08eb0 ioat/perf: allow queue depths > 256
Currently the task and buffer pools are hardcoded to
512 each.  This effectively limits the queue depth
per channel to 256 since we need both source and
destination buffers from the buffer pool.  So make
the pool sizes dynamic based on the user's queue depth
input.

6728c1b8cb ioat/perf: use new spdk_ioat_flush interface
Use the new spdk_ioat_flush interface to batch
doorbell writes - this significantly improves
descriptor throughput.  For now, just set the
threshold for writing the descriptor to half of
the queue depth.  We can always modify this later
to allow very specific thresholds, but for now
this simple change is sufficient.

Increases 512B descriptor throughput at QD=256 from
3.7M/s to 14.0M/s on my Skylake Xeon server.

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.

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.

bb24ce82a6 build: add @: to remaining 'all' targets
It is not ideal to have to add this in a bunch of
different Makefiles, but further consolidation of
Makefiles is going to be a more arduous process.

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
submodule.

a30b5532cb memory: Rename to env
The new env library will wrap all third-party library
calls and be easily swappable with alternate implementations
at build time. For now, it's just the memory library
renamed.

6b1e4e732d Drop libpciaccess and switch to DPDK PCI
This patch also drops support for automatically unbinding
devices from the kernel - run scripts/setup.sh first.

Our generic pci interface is now hidden behind include/spdk/pci.h
and implemented in lib/util/pci.c. We no longer wrap the calls
in nvme_impl.h or ioat_impl.h. The implementation now only uses
DPDK and the libpciaccess dependency has been removed. If using
a version of DPDK earlier than 16.07, enumerating devices
by class code isn't available and only Intel SSDs will be
discovered. DPDK 16.07 adds enumeration by class code and all
NVMe devices will be correctly discovered.

39cc59635a build: include -lrt and -lpthread in LDFLAGS
Simplify the build rules so that common libraries are always linked.

Also fix up a couple of -lpciaccess instances that should have been
changed to $(PCIACCESS_LIB).

cd48a01fcb build: wrap $(CURDIR) relative paths in $(abspath)
Resolve relative paths before using them to clean up command lines.

This should also help shorten the overall command line length that gets
embedded in the binary and used when locating the executable from a
coredump.

cf0871a57e ioat: make channel allocation explicit
Add a parameter to each I/OAT library function that requires a channel
instead of implicitly using the thread-local channel registration model.

I/OAT channels are already reported by the spdk_ioat_probe() attach
callback, so no infrastructure for channel allocation is necessary.
