[OE-core] [PATCH v2 0/1] license: Add support for SPDX 2.0 operators

[Sergei Miroshnichenko]

Composite SPDX license expressions can be constructed using "OR",
"AND" and "WITH" operators: map them to "|" and "&" operators
accordingly.

Recognize long form license identifiers: "[DocumentRef-XXX:][LicenseRef-]YYY".

Tested on the following expressions:
LICENSE = "Artistic-1.0"
LICENSE = "LicenseRef-Artistic-1.0 AND NASA-1.3"
LICENSE = "(LicenseRef-Artistic-1.0 WITH GPL-3.0-with-GCC-exception)
           OR (DocumentRef-spdx-tool-1.2:LicenseRef-NASA-1.3 AND GPL-2.0+)"
