    classes/buildhistory: properly process escaped chars from pkgdata
    
    All values written out to pkgdata are escaped (see write_if_exists() in
    package.bbclass). In practice there tend not to be characters that need
    escaping except in the scriptlets (pkg_preinst, pkg_postinst, pkg_prerm
    and pkg_postrm) where currently we still see the escape codes in the
    corresponding files within buildhistory (e.g. \n and \t) and thus also
    in the output of buildhistory-diff, hindering proper diffing of changes.
    To fix this, when we read values from pkgdata and write them out to
    buildhistory, we need to interpret the escape codes by doing the exact
    reverse of what we do in package.bbclass.
