lib/runscripts/in_datasrc_dir.run: use new local.run
*{.sh,run}: use new begin_target instead of `echo_func; set_make_vars`
lib/runscripts/in_datasrc_dir.run: datasrc_make(): use `if remaking ...` instead of accessing $_remake manually, for clarity
bugfix: lib/runscripts/in_datasrc_dir.run: datasrc_make(): use set_make_vars and $_remake as required in lib/sh/make.sh `remaking`
moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).
lib/runscripts/in_datasrc_dir.run: added datasrc_make(), which runs make in the datasrc dir
lib/runscripts/datasrc_dir.run: moved commands related to any runscript in the datasrc dir to new in_datasrc_dir.run
