fetch2: Add SRPM knowledge

Enable the fetcher to be able to unpack and SRPM.  By default the system will
unpack the contents of the SRPM into the WORKDIR.

A new syntax "unpack=file" was developed for the SRC_URI, to allow for a
recipe to extract a specific file within an SRPM.  An unpack operation will
then be executed on the extracted file.

In order to apply extracted patches (or unpack files not specified with
unpack), you must specify the path using WORKDIR, i.e.:

file://${WORKDIR}/mypatch.patch
