No functional changes.

Add ARGV_ERR() macro for reporting argument trouble.

Do selection of method in varnishd.c, using generic choice function.

Split subarguments into argc+argv at commans, and pass those down to
avoid repetitive and bogus string munging.

Catch more error conditions with respect to subarguments.

Add mini_obj magics to stevedores and slingers.

Generally tidy up along the way.
