Rework rvs a lot (no longer needs complex C dependency tracker!)

Rework ./configure, and how it uses `srcdir'.  Probably broke all the
other packages. Oh well, everything only half-works right now.

-* plugin-run.h:
-	the function _plugin_sh_mktemp() is an ugly hack, it exists
-	because
-	  a) it is secure
-	  b) it is easier to write a hack using methods I understand,
-	     than learn those I don't
-	  c) point `b' especially when I just want to get it working.
-	  d) point `b' especially since I think I coded it in
-	     studyhall one day, which means I didn't have internet
-	     access (no glibc documenation).
-* everything:
-	with plugin commands, have arg1 be a file to write output to
