Move devDeps (tape and related) to root package.

[andreypopp]

Why:

• The idea is to use root package for development.
• We reduce time of npm install in a few times.
• We use consistent versions of tape across all packages.

What else:

• Rewrite symlinking local deps so we symlink only needed deps.
• Add missing deps from server to replica.
• Each package now includes ../Makefile.package.in with install, clean and test targets.
• npm test now delegates running tests to make test.
