profiles: Represent propagated inputs as manifest entries.
* guix/profiles.scm (package->manifest-entry): Turn DEPS into a list of manifest entries. (manifest->gexp)[entry->gexp]: Call 'entry->gexp' on DEPS. Bump version to 3. (sexp->manifest)[infer-dependency]: New procedure. Use it for versions 1 and 2. Parse version 3. (manifest-inputs)[entry->gexp]: New procedure. Adjust to 'dependencies' being a list of <manifest-entry>. * tests/profiles.scm ("packages->manifest, propagated inputs") ("read-manifest"): New fields.
