We've had versioned dependency support in LAYERDEPENDS for quite a long
time, but I can say with pretty good certainty that almost nobody has
used it up to now because it was too strict - the specified version had
to exactly match the version in your configuration or you would get an
error; there was no "greater than or equal" option, which is usually
what you will want given that LAYERVERSION does get bumped from time to
time.
However, users mismatching layer branches and then having their builds
fail later on with some incomprehensible error is still a pretty common
problem. We can't simply use the git branch because not everyone is
always on a branch and the branch names don't always match up (and
that's not an issue). To provide a practical means to address branch
mismatching, I have reworked LAYERDEPENDS version specifications to use
the more familiar "dependency (>= version)" syntax as used with package
dependencies, support non-integer versions, and clarified the error
message a little. If we then take care to bump the version on every
breaking change, it is at least possible to have layers depend on these
changes when they update to match; we can now even support a major.minor
scheme to allow retrospectively adding a version limiter to old branches
when a new branch is created and yet still allow the old branch minor
version to be bumped if needed.
Fixes [YOCTO #5991].

This scheme is used for versioning recipes that are pre-release (alpha,
beta, etc.) within OpenEmbedded, so add some tests to ensure the
appropriate comparison results still hold true.

This adds some basic unit testing for the codeparser and data store code. Many of
the actual test cases were taken from work by Chris Larson's OE-Signatures work but with
changes to adapt to the current bitbake APIs we need to test.
I also imported CoW tests written by Holger Freyther from the original bitbake-test
codebase: http://svn.berlios.de/wsvn/bitbake/trunk/bitbake-tests/tests/ and
some tests from the doctests that were removed in commit:
