[PATCH 00/22] Packaging performance improvements, round 2

[Richard Purdie <richard.purdie@linuxfoundation.org>]

The following patch series contains various performance improvements for 
do_package.

It also includes changes to the sanity testing to start giving warnings 
about packaging variables used without packages being specified, eg:

RDEPENDS = "x"

instead of

RDEPENDS_${PN} = "x"

The final patch in the series stops the packaging code using the non-package
versions in many cases. I'm not planning to merge that one right away, its just
included for illustration and benchmarking purposes now. 

There were three cases I found using bad syntax in OE-Core and the series includes 
patches to fix them.

There is also a useful performance improvement to sstate manipulations to use
hardlinks instead of file copies which should be universally helpful to
build performance of tasks.

The following changes are available in the git repository at:
