Patchwork base.bbclass: support for or operand in LICENSE and for SPDX license names

From: Andrei Gherzan <andrei.gherzan@windriver.com>

base.bblass modfied in order to correctly exlude packages where OE-Style licence naming
is used. In this way licenses as GPL-3, GPLv3, GPLv3.0 will be exluded from a non-GPLv3
build.
The second modification was to include in a non-GPLv3 build packages where LICENSE is
GPLv3 or "something else". For example, qt4-embedded has LICENSE = "LGPLv2.1 | GPLv3".
This package should be included in a non-GPLv3 build as it is LGPLv2.1 or GPLv3.

[YOCTO #1884]
[YOCTO #1844]

A few notes:

I would use the oe.license here
Have a look at meta/classes/copyleft_compliance.bbclass and
license.bbclass to see how we're doing this.

I would also look at pulling this into license.bbclass as a generic
function as I can see a few anticipated uses for it.

Elizabeth,

Thank you very much for you ideas upon base.bbclass: support for or 
operand in LICENSE and for SPDX license names.
I recoded this after your advices. Actually i didn't know about 
oe.license and the idea of having it as a function in license.bbclass 
sounds good to me.

So i will upload this change soon.
