It's been suggested that it would be a useful feature to be able to
easily take a binary from a 3rd party software vendor and integrate
it into an image created by the build system.

* The user can easily use this by:
  # Specify where is the external binary pkg dir
  #EXTERNAL_PACKAGE_DIR = "<path1> <path2> ..."
  # Specify which pkg will be installed
  #EXTERNAL_INSTALL_PACKAGE = "<pkg1> <pkg2> ..."

  Then the pkg1, pkg2 ... would be installed.

  Add an "EXTERNAL_INSTALL_PACKAGE"here since we can't use the existence
  variable (for example, IMAGE_INSTALL), if we add the pkg to the IMAGE_INSTALL,
  it would check whether the pkg is in the PROVIDES, and this is an external
  pkg, it is not in the PROVIDES.

* Main changes:
  - Add external_package.bbclass:
    Add the external package to the repo, the package would be copied
    to deploy/deb/external/<arch>, the add_external_debipk is used by
    ipk and deb, the add_external_deb is just a wrapper.

    Use an "external" directory since we don't want the "internal" pkgs
    to be mixed, and it would be easy to remove them.

  - package_deb.bbclass:
    Create repo for deploy/deb/external

  - rootfs_deb.bbclass
    Add the package that would be installed to INSTALL_PACKAGES_DEB, so
    that it would be installed.
