bin_package.bbclass: binary package recipe class

This is used for the binary package recipe, it's been suggested that it
would be a useful feature to be able to easily take an RPM or similar
containing a software binary from a 3rd party software vendor and
integrate it into an image created by the build system.

* Brief introduction
  - The binary pkg can be .rpm, .deb, .ipk and other formats which can
    be unpacked by bitbake fetcher.

  - Let bitbake unpack the bianry package, just like unpack the source
    package.

  - Skip the do_configure and do_compile.

  - Install the files to ${D}

  - Other steps are similar to the source package's recipe.

* Note:
  - The "subdir" parameter in the SRC_URI is useful for the binary
    package recipe, so I added an example in the comment.

  - I have sent a patch to bitbake-devel mailing list to support
    unpack the .rpm, .ipk, and .deb files.

+# Common variable and task for the binary package recipe.
+# Basic principle:
+# * The files have been unpacked to ${S} by base.bbclass
+# * Skip do_configure and do_compile
+# * Use do_install to install the files to ${D}
+#
+# Note:
+# The "subdir" parameter in the SRC_URI is useful when the input package
+# is rpm, ipk, deb and so on, for example:
+#
+# SRC_URI = "http://foo.com/foo-1.0-r1.i586.rpm;subdir=foo-1.0"
+#
+# Then the files would be unpacked to ${WORKDIR}/foo-1.0, otherwise
+# they would be in ${WORKDIR}.
