Add "source" command; prepare removal of "autoscr" command

According to the doc/feature-removal-schedule.txt, the "autoscr"
command will be replaced by the "source" command in approximately 6
months from now.

This patch prepares this change and starts a 6 month transition
period as follows:

- The new "source" command has been added, which implements exactly
  the same functionlaity as the old "autoscr" command before
- The old "autoscr" command name is kept as an alias for compatibility
- Command sequences, script files atc. have been adapted to use the
  new "source" command
- Related environment variables ("autoscript", "autoscript_uname")
  have *not* been adapted yet; these will be renamed resp. removed in
  a separate patch when the support for the "autoscr" command get's
  finally dropped.

- * autoscript allows a remote host to download a command file and,
- * optionally, binary data for automatically updating the target. For
- * example, you create a new kernel image and want the user to be
- * able to simply download the image and the machine does the rest.
- * The kernel image is postprocessed with mkimage, which creates an
- * image with a script file prepended. If enabled, autoscript will
- * verify the script and contents of the download and execute the
- * script portion. This would be responsible for erasing flash,
- * copying the new image, and rebooting the machine.
