Re-implement the source-check and external-deps targets
The new DL_MODE variable dispatches between the various download implementations of each method (Git, Subversion, Wget) to deal with the normal download (default mode, 'DOWNLOAD'), the source-check ('SOURCE_CHECK') and to show the external dependencies for external-deps ('SHOW_EXTERNAL_DEPS'). For the latter, the legacy script wget-show-external-deps.sh is no longer required as $(WGET) isn't called directly anymore but always through the DOWNLOAD helper.
