Added a new API spdk_fd_group_add_ext(), which accepts extended

The spdk_event_handler_opts has events and fd_type. This provides
flexibility in handling different types of fds, which may require
specific operations to be performed when an event is generated.

dif: Update spdk_dif_error structure to bump SO_VER forcefully

We will match enum spdk_dif_pi_format with the NVMe specification.

enum spdk_dif_pi_format was added a year ago. we need users to recompile
their application if they use enum spdk_dif_pi_format.

However, enum spdk_dif_pi_format was not used in any data structure and
ABIDIFF tool could not detect the change.

The change breaks ABI. Hence, we should bump SO_VER of lib/util in any
other way to notify the change to users.

The cleanest way to do that without hacking check_so_deps.sh is to add
a reserved field to spdk_dif_error structure.

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:

build: enable Wpointer-arith in selected libraries

There's an organization, called Timerland SIG [1], that uses SPDK's NVMe
driver to implement NVMe Boot Specification under UEFI. The UEFI EDK2
build environment uses both gcc and msvc. While SPDK can be built
without any issues with gcc, msvc complains about a few things, one of
which is void pointer arithmetic. So, to make Timberland's effort
easier, Wpointer-arith is enabled in the libraries they're using.

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.

util: Add spdk_ioviter for iterating iovecs

spdk_ioviter_next will walk through two iovecs and yield pointers
to common length segments. For example, given a source iovec (siov) with
4 1KiB elements and a destination iovec (diov) with 1 4KiB element, the
following will happen:

first spdk_ioviter_next:

src = siov[0].iov_base
dst = diov[0].iov_base
len = 1KiB

second spdk_ioviter_next:

src = siov[1].iov_base
dst = diov[0].iov_base + 1KiB
len = 1KiB

third spdk_ioviter_next:

src = siov[2].iov_base
dst = diov[0].iov_base + 2KiB
len = 1KiB

fourth spdk_ioviter_next:

src = siov[3].iov_base
dst = diov[0].iov_base + 3KiB
len = 1KiB

fifth spdk_ioviter_next:

len = 0

This is a useful utility for performing operations where both the source
and destination are scattered memory. As an example and a test vehicle,
spdk_iovcpy has been updated to use this internally.

util: add zipf random number generator

zipf is a power law probability distribution. When
applied to performance testing of block devices, it
will select blocks over the full range of LBAs, but
will more frequently select lower-numbered LBAs.
The theta parameter governs the distribution - higher
values of theta will concentrate the distribution on
a smaller number of LBAs.

Note that fio supports zipf, so adding it to SPDK
will enable our perf tools (bdevperf, nvme-perf) to
provide similar functionality.
