scripts/unpack: move $BUILD/.stamps/unpack to $PKG_BUILD/.openelec-unpack. Add support for PKG_SOURCE_DIR: if set this automatically rename extracted sourcefolders to the $PKG_NAME-$PKG_VERSION format. Remove support for the already deprecated and not more used $PKG_DIR/rename scripts. Deprecate post_unpack() function. Cleanup.
