Subject: Implement dump directive

It can be used to print (to stderr) a human-readable representation of the
current scope or a list of targets. For example:

dump                           # Dump current scope.
dump lib{foo} details/exe{bar} # Dump two targets.

This is primarily useful for debugging as well as to write build system
tests.
