module/iobuf: introduce iobuf module

This gives us a place to initialize iobuf pools, specify subsystem

We allow users to configure the size of the pools either through the
options in spdk_bdev_opts or through the new RPC, iobuf_set_options.
The second option has higher priority, so it will override the options
set by the bdev layer.

Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license
header updates, formatting changes, etc). Contribution date used
"--follow -C95%" to get the most accurate date.

Note that several files in this patch didn't end the license/(c)
block with a blank comment line so these were added as the vast
majority of files do have this last blank line. Simply there for
consistency.

Previously SPDK use libvfio-user library to provide emulated NVMe
devices to VM, but it's limited to NVMe device type only. Here we
add SPDK vfu_target library abstraction based on libvfio-user which
supports more PCI device types.

We will add virtio-blk and virtio-scsi devices emulation based on
vfu_tgt library in following patches, actually this library can
support NVMe emulation too, due to the fact that the NVMe emulation
is already exist, so we will keep the NVMe emulation which based on
libvfio-user directly as it is.

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.

scheduler: create public API and subsystem for scheduler/governor

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.

module/event: add subsystem interdependencies

The SPDK application framework defines a list of event subsystem
dependencies. When linking against individual shared libraries, it is
useful for this dependency structure to be codified in the shared
libraries themselves.

For example, when linking a bdev based application against
libspdk_bdev.so, one might wish to only specify this shared object at
link time. However, when you actually run the application, it will fail
to start because it is not linked to the copy and vmd subsystems.
However, once thesedependencies are added, one can effectively link
against only the exact subsystems they need and any dependent subsystems
will be linked in automatically.
