packagegroups are allarch and shouldn't change depending on the target
or machine selected. In general they should have good stable namespaces
for their dependencies. As such we can exclude them from rebuilding when
dependency checksums change.

There are some left over tab characters in the python functions. This
removes them and resolves python 3 errors.

Fixes "bitbake-diffsigs -t" for changes to the stamp directory layout,
and this time uses the actual value of STAMP to get the location of
sigdata files in the stamp directory rather than trying to do it
manually, which should be a little more robust.

Add a function that can be used from BitBake code which will find
signature data (sigdata/siginfo) files based on specified criteria, and
hook it into BitBake as bb.siggen.find_siginfo.

As discussed on the mailing lists, using a suffix to package names is
hard and has lead to many recipes having to do PKGSUFFIX games. Its
looking extremely hard to scale nativesdk much further without hacking
many recipes.
By comparison, using a prefix like multilib does works much better and
doesn't involve "hacking" as many recipes. This change converts nativesdk
to use a prefix using the existing multilib infrastructure.

gcc exposed this issue where cross gcc recipes were not having
same task checksums as libgcc or gcc-runtime the target recipes
which use same shared workdir and it was triggering the unpack
fetch and patch tasks to reexecute and hence the trouble
Now that we have more than 1 package to consider lets combine
the check
Thanks RP for help and this is on the line of patch

If we don't do this, target and cross recipes end up with different sstate
checksums for shared work directory tasks which is bad in the case of gcc.
It leads to multiple fetch/unpack tasks against the shared directory
which ends up with build failures/races.

its desireable for other layers to be able to append to the list of packages
with 'safe ABI's which are excluded from the sstate signatures.
I can't emphasise enough how careful you need to be with this list, anything
excluded here needs to be things which don't change interface and are consistent
between different machines.

Adding dependencies on machine specific recipes from generic packages
causes a rebuild of the generic package per machine if using signatures
for the stamp files which is unacceptable.
We need to declare that RRECOMMENDS on kernel-module-* are safe
and that we shouldn't care about these machine specific dependencies
from a stamp perspective. This change adds code which does this.
It depends on a change in bitbake to expose the dataCache object
which can be used to make the calculations we need to allow this to
work correctly.

signatures
Where we have machine specific recipes with well defined behaviour, it makes
no sense to rebuild recipes with these as dependencies whenever the machine
changes. This patch lists those well behaved recipes and excludes them from
the task signatures so we can change MACHINE without invalidating existing
PACKAGE_ARCH binaries.

This patch adds SignatureGenerator classes specific to OE. For now,
these emulate the previous behaviour with the exception that
dependencies on quilt-native are now ignored for checksum purposes.
The intent is to allow easier experimentation and customisation of
this code in future as a result of these changes.
Note that these changes require pending bitbake patches.
