The bblayer abstraction makes it where multiple layers can be
configured and used at the same time. Some layers make changes to
support a specific machine, and should not have any affect when other
machines are in use.
For linux-yocto, all bsps are created with a user-config.cfg and
user-config.cfg and user-patches.scc. This means that those files
will be pulled from the first location found, which might correspond
to files customized for a different machine.
Instead of using the names user-config.cfg and user-patches.scc, I
propose a machine specific name be used such as
{{=machine}}user-patches.scc and {{=machine}}user-config.cfg. This
would necessitate that all references changed to these new names,
which would affect the yocto-bsp and yocto-kernel scripts.
With this change, it would be possible to have multiple machine BSPs
searched at the same time and to select which to build against by
using a command like MACHINE=qmeux86 bitbake core-image-sato to
override the default.
Note many of the standard BSPs do not seem to suffer this problem as
they do not use the common files user-config.cfg and user-patches.scc
that the yocto-* scripts depend upon.
Additions by Tom Zanussi:
- renamed user-config.cfg to {{=machine}}-user-config.cfg everywhere
- renamed user-patches.scc to {{=machine}}-user-patches.scc everywhere
- added the user-config/patches SRC_URI items to the qemu -rt kernel recipes

Add a "branches_base" property that can be used to allow only matching
branches to be returned from all_branches().

The current code assumes that builddir == srcdir/build, which it
obviously isn't sometimes. Use BUILDDIR to get the actual builddir
being used.

Previous versions of yocto-bsp mapped every input element to a unique
variable name, which is what the current property value display code
expects. When that was changed to a nested form, the display code
wasn't updated to match - this updated does that.
