To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.
Increasing major so version after LTS, allows the future releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.
Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 23.05

Looks like this was left over from prior LTS, to avoid that
make sure it is only skipped when running against v23.01.x as latest
release.
This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests
Short reference to how the versions were changed:

for((i=$MAX;i>0;i-=1)); do find . -name "Makefile" -exec \

1) It doesn't work correctly at all on C++ files.
2) It often fails on functions that return enums, or long type names
Deal with 1) by adjusting the check_format.sh script to only tell astyle

Almost all of these files share the exact same license text,

because the third clause contains company names - most say

When nvmf_tgt application shuts down, it stops all
subsystems, than destroyes poll groups and than
destroyes nvmf_tgt. Part of nvmf_tgt destruction is
destruction of subsystems and this process may require
cross thread communication but since poll groups and
threads are already destroyed, we may get segfaults.
One possible solution is to change the order and destroy
nvmf_tgt before destroying poll groups but it doesn't
work since nvmf_tgt is registered as io_device and
poll groups have its channel, so it can't be destroyed
while poll groups exist.
This patch adds a new state to nvmf_tgt state machine
which destroys all subsystems before destroying poll
groups and nvmf_tgt. It guarantees that all threads
exist when subsystems are destroyed.
Also rename state NVMF_TGT_FINI_FREE_RESOURCES to

This patch moves schedueler and governor related API from
the internal event.h to public scheduler.h.
With this it is possible to create subsystem responsible
for handling the schedulers.
Three schedulers and a governor were moved to scheduler modules
from event framework.
This will allow next patch to add JSON RPC configuration
to the whole subsystem.
Along with easier addition of other schedulers.
Removed debug logs from gscheduler, as they serve little purpose.

Parses and verifies hexadecimal cpu bit mask specified by the user.
Added verification to check for cpu cores range, making sure poll groups cores
assigned within the range of cpu cores allocated for the application.
RPC nvmf_set_config now takes an argument to configure ‘poll groups’,
a new parameter for NVMf subsystem. This parameter sets a CPU mask
to spawn threads which run an event loop for a ‘poll group’.

This patch also adds a script that can generate
a bpftrace script snippet with string maps for
needed enumerations (currently nvmf_tgt_state and
spdk_nvmf_subsystem_state). This allows us to
dynamically generate this from the source code, and
can be extended for other enums we may want to

Passing cpu_mask hints that match only single core were
usefull to prevent any accidents when doing round-robin
in case of 'static' scheduler.
In practice this is not required in case of 'static' scheduler,
the threads will be spread out over all reactors anyway.
This hinders other schedulers which try to respect the cpu_mask
hints, as they would not move the thread to any reactor.
Preventing bunching up less used threads on single reactor.
Drawback of this patch is that poll group names will not match
the cores they are on.

To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.
Increasing major so version after LTS, allows the quarterly releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.
Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 21.04
release.
This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests

This is a step to prepare for deletion of conf.c.
NVMe-oF target application always creates the default 'nvmf_tgt'.
This was done as part of legacy configuration parsing, but does
not belong there at all.
Acceptor poll rate and max subsystems are set via RPC before this
step, or via legacy config. Since this patch creates target before
parsing the config, options defined there no longer change the target.
Parsing of legacy config will be removed further down the series,
so no need to refactor to keep the original functionality.
