newer kernel. This moves the example to the 4.2 stable
kernel and appends -custom to the VERSION string.

* PR = "r0" is the default, no need to set it (and most people won't
  need to set it anyway with the PR service)
* PV = "0.1" is already set by virtue of 0.1 being in the filename

The kernel development manual recommends making a copy of
linux-yocto-custom, while the comments in the recipe talk about
bbappends.

To synchronize the two, we remove the bbappend references from the
recipe and instead indicate that a copy should be updated.

It was pointed out that the kernel development documentation recommends
making a copy of linux-yocto-custom, while the comments in the recipe
itself suggest a bbappend.

To keep things consistent between these two sources, we update the
comment in the recipe itself to also recommend a copy (and rename).

As reported by Andrea, defconfigs created with savedefconfig should specify
their expansion mode as "--alldefconfig' for custom yocto recipes. To ensure
that this is documented, we can add a comment in the skeleton recipe.

The SRCREV_machine line does not work without having name=machine
attribute in SRC_URI.

This error is seen if the custom kernel recipe is used without
the name attribute:

The Yocto kernel tools look for SRCREV_machine in do_validate_branches,
if it's empty, it just returns and silently continues. This likely needs
at least a warning. However, this recipe should be using SRCREV_machine,
and not just SRCREV.

A lot of our recipes had short one-line DESCRIPTION values and no
SUMMARY value set. In this case it's much better to just set SUMMARY
since DESCRIPTION is defaulted from SUMMARY anyway and then the SUMMARY
is at least useful. I also took the opportunity to fix up a lot of the
new SUMMARY values, making them concisely explain the function of the
recipe / package where possible.
