thread: remove pool parameter from spdk_iobuf_for_each_entry

We always want to iterate across the entire iobuf_channel, so just
make the iterator do exactly that, rather than requiring the caller
to have to iterate both of the pools itself.

This both simplifies the calling logic, and prepares for upcoming
changes which will support multiple NUMA node caches in one channel.

so_ver: increase all major versions after SPDK 24.01

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.

This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components

Due to patch below being introduced after v24.01 code freeze,
bdev lib version should not be increased:
61623c5ca9 bdev: add spdk_bdev_io padding in place of io_submit_ch

Short reference to how the versions were changed:

"--follow -C95%" to get the most accurate date.

Note that several files in this patch didn't end the license/(c)

Replace most BSD 3-clause license text with SPDX identifier.

Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file. This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.

Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text. There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".

Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.

thread: Change direct accesses to poller outside lib/thread to helper functions

Most accesses to the struct spdk_poller outside lib/thread have been
done via functions but a few direct accesses remain.

Change these to indirect accesses by addinng a few helper functions
as SPDK internal APIs.

Add spdk_poller_get_name() to get the name of the poller.

Remove spdk_poller_state_str() and add spdk_poller_get_state_str().
Exposing enum spdk_poller_state outside lib/thread is not really
necessary.

This removal requires us to update major SO version.

Add spdk_poller_get_period_ticks() to get the period ticks of the
poller.

Add struct spdk_poller_stats and spdk_poller_get_stats() to get
the stats of the poller.

The next patch will move the definition of struct spdk_poller and
enum spdk_poller_state from include/spdk_internal/thread.h to
lib/thread/thread.c.

thread: Add SPDK internal APIs spdk_thread_get_first/next_active/timed/paused_poller()

The following patches will introduce red black tree to manage
timed pollers efficiently but it will be based on macros available only
in lib/thread/thread.c. Hence then it will be difficult to expose the
internal of timed pollers tree outside the file. On the other hand,
we do not want to include JSON into the file.

Hence add a few SPDK internal APIs to iterate pollers list transparently.

For spdk_thread_get_next_active/timed/pause_poller(), we omit the parameter
thread and get it internally from poller->thread even if the names include
the term "thread". This will be slightly cleaner.
