The buildDepot function now takes a "depotInputs" argument that
propagates "portInputs" and "depotInputs" across packages.
Drop the stdcxx package that includes a dev output and just use
the simple depot package for now.
Retrieve ROMs in the common case by full store path. This reduces
the need for route policies for driving relative requests into
absolute package paths.
Making library requests by absolute path required libraries to be
stored in the core image as such, and it follows that program
binaries should be handled in the same way. This makes requests
to core and to a file-system store more consistent, and makes
dependency detection more robust.
