This is a quick audit of only the most obviously wrong licenses
found within OECore. These fixes fall into four areas:

- LICENSE field had incorrect format so that the parser choked
- LICENSE field has a license with no version
- LICENSE field was actually incorrect
- LICENSE field has an imaginary license that didn't exist

This fixes most of the LICENSE warnings thrown, along with my prior
commit adding additional licenses to common-licenses and additional
SPDXLICENSEMAP entries.

HOWEVER..... there is much to be done on the license front.
For a list of recipes with licenses that need obvious fixing see:

https://wiki.yoctoproject.org/wiki/License_Audit

That said, I would suggest another license audit as I've found
enough inconsistencies. A good suggestion is when in doubt, look at
how openSuse or Gentoo or Debian license the package.

As discussed on the mailing list, this variable isn't useful and if wanted
would be better implemented by distros using pn-X overrides.

This patch executes:

find . -regex ".*\.\(bb\|inc\)$" | xargs sed -i '/^PRIORITY = ".*"$/d'

against the tree removing the referenced. Thanks to Phil Blundell for
the command.

Transfig provides fig2dev, which is used when building
documentation for many packages.
