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.
