ref-manual; mega-manual: Edits to further define packaging process

In response to community input where developers were attempting to
locate information on how to write packages out to a directory
other than ${DEPLOY_DIR}/<package_type>, I updated the "Package
Feeds" section, added several new DEPLOY_DIR_* variables, updated
four classes, and updated four tasks.  Here are some details:

 * Made changes to the "Package Feeds" section to provide more
   accurate information in the package feeds directory structure
   used by the build system in build/tmp.  These changes included
   updating the figure itself and some explanatory text.

 * Updated the DEPLOY_DIR variable description.

 * Added new variable descriptions for DEPLOY_DIR_DEB, DEPLOY_DIR_IPK,
   DEPLOY_DIR_RPM, and DEPLOY_DIR_TAR.

 * Updated the related classes: package_deb, package_ipk, package_rpm,
   and package_tar.

 * Updated the related tasks: do_package_write_deb, do_package_write_ipk,
   do_package_write_rpm, and do_package_write_tar.
