1094dd940e cleanup compat header inclusions
With symbols going though experimental/stable stages, we accumulated
a lot of discrepancies about inclusion of the rte_compat.h header.

Some headers are including it where unneeded, while others rely on
implicit inclusion.

Fix unneeded inclusions:
$ git grep -l include..rte_compat.h |
  xargs grep -LE '__rte_(internal|experimental)' |
  xargs sed -i -e '/#include..rte_compat.h/d'

Fix missing inclusion, by inserting rte_compat.h before the first
inclusion of a DPDK header:
$ git grep -lE '__rte_(internal|experimental)' |
  xargs grep -L include..rte_compat.h |
  xargs sed -i -e \
    '0,/#include..\(rte_\|.*pmd.h.$\)/{
      s/\(#include..\(rte_\|.*pmd.h.$\)\)/#include <rte_compat.h>\n\1/
    }'

Fix missing inclusion, by inserting rte_compat.h after the last
inclusion of a non DPDK header:
$ for file in $(git grep -lE '__rte_(internal|experimental)' |
  xargs grep -L include..rte_compat.h); do
    tac $file > $file.$$
    sed -i -e \
      '0,/#include../{
        s/\(#include..*$\)/#include <rte_compat.h>\n\n\1/
      }' $file.$$
    tac $file.$$ > $file
    rm $file.$$
  done

Fix missing inclusion, by inserting rte_compat.h after the header guard:
$ git grep -lE '__rte_(internal|experimental)' |
  xargs grep -L include..rte_compat.h |
  xargs sed -i -e \
    '0,/#define/{
      s/\(#define .*$\)/\1\n\n#include <rte_compat.h>/
    }'

And finally, exclude rte_compat.h itself.
$ git checkout lib/eal/include/rte_compat.h

At the end of all this, we have a clean tree:
$ git grep -lE '__rte_(internal|experimental)' |
  xargs grep -L include..rte_compat.h

72206323a5 version: 22.11-rc0
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.

44c730b0e3 sched: add PIE based congestion management
Implement PIE based congestion management based on rfc8033.

The Proportional Integral Controller Enhanced (PIE) algorithm works
by proactively dropping packets randomly.
PIE is implemented as more advanced queue management is required to
address the bufferbloat problem and provide desirable quality of
service to users.

Tests for PIE code added to test application.
Added PIE related information to documentation.

b1094939a5 build/windows: remove separate list of libs
Rather than maintaining a separate list of libraries which are to be
built on windows, use the standard library list and explicitly add to
each library that is not to be built a check for windows and disable
the library at that per-lib level. As well as shortening the main
lib/meson.build file, this also leads to the build summary at the end of
the meson config run correctly listing the libraries which are not to be
built.

99a2dd955f lib: remove librte_ prefix from directory names
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'
