279b7babe4 lib/trace_parser: method for iterating over entries
Added a definition of a parsed trace entry and a function allowing for
iterating over these objects.  The difference between a parsed and a
regular trace entry is that it includes more information gathered while
processing the trace file (e.g. lcore, object statistics) and provides a
contigous buffer for trace arguments.

For now, only lcore and the pointer to the actual trace entry are
filled.  Tracepoint arguments and object statistics will be added in
subsequent patches.

d919a197d6 lib/trace_parser: add trace_parser library stubs
This library will provide functions that parse traces recorded by an
SPDK application.  This includes merging traces from multiple cores,
sorting them by their timestamp and constructing trace entries spanning
across multiple buffers.  All of these tasks are currently implemented
in the spdk_trace app, so most of its code will be moved here (this is
the reason for using C++).

The motivation for extracting this code to a library is to be able to
use it from places other than the spdk_trace app, specifically the
`scripts/bpf/trace.py` script.

The main reason for creating a separate library instead of extending
libtrace is to avoid pulling in all of its dependencies.  ISA-L is the
most problematic, as we only build it as a static library, which makes
it impossible to use with dlopen (making it unusable in scripts).

1bea880598 nvme: asynchronous register operations
This patch introduces asynchronous versions of the ctrlr_(get|set)_reg
functions.  Not all transports need to define them - for those that it
doesn't make sense (e.g. PCIe), the transport layer will call the
synchronous API and queue the callback to be executed during the next
process_completions call.

97385af196 nvmf: Fix double controller destruction when subsys is deleted
When a subsystem is being deleted, we disconnect all qpairs
and when the last qpair for some controller is disconnected,
we start controller desctruction process. This process requires
to send a message to subsystem's thread to remove the controller
from the list in the subsystem and after that send a message to
controller's thread to release resources.
The problem is that the subsystem also destroys all attached
controllers. This order is unpredictable and we may get
heap-use-after-free or double free.

To fix this problem we can rely on the fact that the subsystem
can only be destroyed in incative state, that means that all
qpairs linked to the subsystem are already disconnected and
all controllers are already destroyed or in the process of
destruction.

spdk_nvmf_subsystem_destroy API is now can be asyncrhonous,
it accepts a callback with cb argument.

3cb9bc2593 nvme: add spdk_nvme_ctrlr_prepare_for_reset()
This new API signals that the ctrlr will soon be
reset. This allows the transport to skip unnecessary
steps in following calls to the driver prior to the
reset - for example, skipping PCIe DELETE_SQ/CQ
commands when freeing an IO qpair.

Note that if we are deleting a qpair after
prepare_for_reset was called, and the qpair is
still waiting for a CREATE_IO_CQ or CREATE_IO_SQ,
we cannot poll for those commands to complete,
but we also cannot free the qpair immediately.
So set a flag for this case to defer the
destruction until the outstanding CREATE_IO_CQ or
CREATE_IO_SQ callback is invoked (typically as an
aborted command when the reset happens).

Three schedulers and a governor were moved to scheduler modules

Along with easier addition of other schedulers.

07bfc3cbe9 nvmf: Add anagrpid to ns and count number of ns per ANA group in subsystem
This is the first patch in the patch series to control ANA states not only
as a unit of subsystem listener but also as a unit of ANA group and create
user preferred mapping between namespaces and ANA groups within a single
subsystem.

This patch adds anagrpid to both spdk_nvmf_ns and spdk_nvmf_ns_opts, and adds
ana_group array to spdk_nvmf_subsystem to count number of namespaces per ANA
group within a single subsystem. The size of the ana_group array is equal
with the size of the namespaces.

For each subsystem, allocate ana_group array regardless of the value of
ana_reporting of the subsystem.

For each namespace, at its creation, initialize anagrpid explicitly to be equal
with nsid by default and increments the corresponding entry of the ana_group
array of the subsystem regardless of teh value of the ana_reporting of thee
subsystem.

Hence the contents of the created ANA log page is not changed even if the
algorithm to crete ANA log page is changed.

Additionally this patch adds a unit test case that one ANA group
has multiple namespaces.

Callback for bdev modules is called 'module_fini',
meanwhile after its execution bdev modules were to call
'spdk_bdev_module_finish_done()'.

This function carries incorrect name, so it was deprecated

413d25b036 bdev_module: add async fini_start()
fini_start() is called for each bdev module before
iterating over all unclaimed bdevs to unregister them.
This allows bdev modules to behave differently during
each such unregister. Ex. unloading lvol store when
all lvol bdevs on it are unregistered.

Another use of this callback is to unclaim all bdevs
that can be at that point. Especially ones that will
not receive callback due to no bdev registered.
Ex. offline raid bdev, when some underlying bdevs are missing.

fini_start() being synchronous does not help in cases
where to release claim on the bdev, an asynchronous operation
is required. Ex. lvol store with no bdevs present, requires
async lvs unload to be called.

This patch adds async_fini_start flag for the bdev modules,
to be used when async fini_start is required. When done,
bdev module has to call spdk_bdev_module_finish_start_done().

15b7d3bacc nvme/pcie: defer bad vtophys to completion context
The pcie layer can't always detect bad addresses
in the request at submission time - for example,
the transport may not have any trackers available
and the request gets queued at the generic
nvme level.

So this means that we might detect vtophys failures
during submission time, or in a process_completions
context - the latter happening when we complete
one request which triggers submitting a new request.

Currently if the vtophys failure happens during
submission context, we return -EFAULT to the
caller *and* call the completion callback.  Nowhere
else in the driver do we do both - the intention
has always been that you get one or the other.

So make all of this consistent by tagging the
tracker and the qpair with a flag if we hit a vtophys
error in the submission path.  Return 0 to the caller,
who will then later get a completion callback for the
bad request when the qpair is next processed for
completions.

I considered a separate TAILQ to hold these 'bad'
trackers, but that would have required duplicating
quite a bit of the tracker completion code for this
one case.  The flag on the pqpair is already in the
hot cacheline, so it's cheap to check it.  We will
only interate the outstanding_tr list when that flag
is set, so this should have zero impact to performance.

Fixes issue #2085.

320ab72fb5 util: Add macro SPDK_SIZEOF_MEMBER to get size of a member of a struct
We find a few files to get the size of a member of a struct. How to
do it is a little complex. So add a macro to do it will be helpful
to read the current code and develop new features.

lib/dif had used member_size() internally but Linux use sizeof_member()
as the macro. Besides, SPDK have used upper case letters for similar
macros, SPDK_CONTAINEROF() and SPDK_COUNTOF(). Hence spdk_member_size()
may be good but propose SPDK_SIZEOF_MEMBER() as the macro.
