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

Previously, it was possible for a library to slip through

Replaced single global write buffer with the per-io_channel write
buffers. This means that the "rwb" module and all of its references
were removed and replaced with the recently added interfaces.

The patch adds support for retrieving asynchronous media management
events sent by the drives. SSDs needs to inform the host of various
incidents concerning the data placed on the media. The events include
wear-leveling, read disturb, and background data refresh.
In order to poll for this asynchronous events, a separate thread is
added that polls for completion of admin commands for each of Open
Channel disk and dispatches the ANM events to the appropriate block
devices.

On regular SSDs the FTL is part of firmware, whereas Open Channel
enables moving it to the host and allows for having full controll
of data placement on the device.

* logical to physical address map
* read / write buffer cache
* wear-leveling
* bad block management
