Expand description

Builder for non-genesis Actions

SourceChain::put takes one of these rather than a raw Action, so that it can inject the proper values via ActionBuilderCommon, rather than requiring surrounding code to construct a proper Action outside of the context of the SourceChain.

Genesis actions cannot be built with this method, because the way SourceChain is written, the agent key is not known until after genesis is performed, and the agent key is one of the values injected rather than provided by this builder. (There is also the problem that the Dna action is a special case as it has no prev_action, and generalizing ActionBuilderCommon just to make that optional is a bit inconvenient.) SourceChain::genesis already handles genesis in one fell swoop.
