bitbake offers a choice of DEB, RPM or IPK packaging. To a degree the
choice is functionally arbitrary for image generation but control over
the package format becomes important if we want to:
1. Include runtime package management functionality in the firmware image
2. Mess about with the packages on the build system
With respect to 1 the IPK format and opkg (an ipk package manager) are
designed for embedded systems[1] - by contrast to RPMs have heavier
dependencies and a greater impact on the size and complexity of the
firmware image.
Regarding 2, the embedded nature and the need for opkg to work without
much fuss leads to a lower configuration barrier by comparison to RPMs.
With ipk it becomes possible to reuse the packages built during image
preparation for core analysis without needing to generate an SDK:

This approach documented in the Poky Reference Manual:
https://www.yoctoproject.org/docs/1.0/poky-ref-manual/poky-ref-manual.html#platdev-gdb-remotedebug-launch-gdb-inferiorbins
Switch all machines to IPK to align the debugging experience with
upstream's documentation and to facilitate efficient use of packaged
software at runtime.

This is apparently not actually working anymore and is removed in the
next poky update.

The meta-ibm layer supported two different DISTROs depending on the
machine being built. This caused complexity since the user needed to
remember to specify the DISTRO name, in addition to the CI build scripts
needed to check for the machine name being built to override the default
DISTRO.
For simplification, remove the openbmc-witherspoon DISTRO, which is the
openpower DISTRO plus additional features, and move these features to
the machine configuration files. Make the openpower DISTRO the default.
Tested: Built witherspoon and p10bmc using "source setup <machine> build"
followed by "bitbake obmc-phosphor-image" without specifying the
DISTRO. Verified witherspoon built a ubi image and p10bmc built
a emmc image.

Replace rainier with p10bmc as build target. Keep the rainier.conf as a
symlink to p10bmc.conf to allow the transition. Remove the rainier.conf
and the machine override from p10bmc.conf in a later commit to complete
the replacement.
Tested: Built rainier and p10bmc and checked for some files/service
units to exist on both.

This system will no longer be supported or maintained. Drop to minimize
cruft.

The metadata common to all IBM systems is confusingly split between
meta-ibm and meta-witherspoon. Move everything to meta-ibm.
The meta-ibm README is re-written to more accurately reflect the scope
of the layer.
Allow the configuration samples (bblayers.conf.sample,
local.conf.sample) to be sourced from either meta-ibm or
meta-witherspoon until such a time that any workflows and tooling have
had the opportunity to move to meta-ibm.
