d477eee312 Rework the test/releasetest.tcl script so that it uses the autoconf makefile 
instead of the test/releasetest.mk makefile.  Also add options like --dryrun
and --buildonly.  Omit the --makefile option and replace it with --srcdir
with the default computed relative to the releasetest.tcl script itself.

later add the keyinfo cache back but only enable it when shared-cache mode
is off.
