Start a new release cycle with empty release notes.
The ABI version becomes 23.0.
The map files are updated to the new ABI major number (23).
The ABI exceptions are dropped and CI ABI checks are disabled because
compatibility is not preserved.
Special handling of removed drivers is also dropped in check-abi.sh and
a note has been added in libabigail.abignore as a reminder.

rte_vhost_clear_queue_thread_unsafe() supports to clear
in-flight packets for async enqueue only. But after
supporting async dequeue, this API should support async dequeue too.
This patch also adds the thread-safe version of this API,
the difference between the two API is that thread safety uses lock.
These APIs maybe used to clean up packets in the async channel
to prevent packet loss when the device state changes or
when the device is destroyed.

In async data path, when vring state changes or device is destroyed,
it is necessary to know the number of in-flight packets in DMA engine.
This patch provides a thread unsafe API to return the number of
in-flight packets for a vhost queue without using any lock.

The punctuation after the `global` keyword should be colon, not
semicolon. The default gcc linker accepts both colon and semicolon, but
the gold linker will report syntax error if we use semicolon after the
`global` keyword.

This commit defines rte_vhost_power_monitor_cond which is used to pass
some information to vhost driver. The information is including the
address to monitor, the expected value, the mask to extract value read
from 'addr', the value size of monitor address, the match flag used to
distinguish the value used to match something or not match something.
Vhost driver can use these information to fill rte_power_monitor_cond.

There is no reason for the DPDK libraries to all have 'librte_' prefix on
the directory names. This prefix makes the directory names longer and also
makes it awkward to add features referring to individual libraries in the
build - should the lib names be specified with or without the prefix.
Therefore, we can just remove the library prefix and use the library's
unique name as the directory name, i.e. 'eal' rather than 'librte_eal'
