[PATCH RFC v2 0/2] bitbake-setup: add source choices

A previous series raised the idea of defining multiple named source sets
in the top level configuration. [1]

Alex suggested selecting sources before BitBake configurations, making
sources and source-choices mutually exclusive, and discussing filters
separately.

This RFC implements the base mechanism:

  * Config files define exactly one of sources or source-choices.
  * Existing sources configurations keep their current behavior.
  * source-choices are selected before BitBake configurations.
  * Positional arguments use a source-first prefix grammar:

    bitbake-setup init <config> [source-choice] [bitbake-config] [fragments...]

  * A single unexpired source choice can be auto-selected.
  * Multiple source choices prompt, or fail in non-interactive mode.
  * The selected source choice is stored and replayed explicitly.
  * Source choices can have an expires field.

The prefix grammar means users cannot specify a BitBake configuration
positionally while leaving source choice interactive. They must either
specify the source choice first, or make selections interactively from
source-choice selection onward.

This patch series replaces the release-specific OE and Poky registry
files with consolidated examples to demonstrate how source choices can
combine the existing master, whinlatter and wrynose configurations.

The consolidated registry examples intentionally do not preserve the
exact setup-dir-name behavior of the existing release-specific files.
Today, setup-dir-name can substitute oe-fragments-one-of selections, but
it has no way to refer to the selected source choice. Possible follow-ups
include a built-in source-choice substitution variable or a different way
to model source/config combination metadata. For a substitution variable,
we have to prevent collision with a fragment choice.

This RFC intentionally leaves documentation out until the feature shape
is agreed.

Changes in v2:
  * Make sources and source-choices mutually exclusive.
  * Select source choices before BitBake configurations.
  * Store the selected source choice for non-interactive replay.
  * Add consolidated OE and Poky registry examples.
