DL multiple batch updates.

[fchirica]

Allows to split a batch updates into multiple commands, by setting publish_on_chain=False inside the batch_update. If using the option, a new batch update will be continued on top of the previous one, which is saved only locally. It's possible to discard the unpublished batch by doing clear_pending_roots, or to publish it by doing publish_pending_root. Internally, this implements the new root status PENDING_BATCH, which works similarly to the previous PENDING root, except it allows batch_update to build on top of it and it's never published on chain - when it gets published, it'll change to the PENDING status.

I misunderstood and thought the pending batch -> committed status was a permanent thing rather than an intermediate change that would get reverted. My above review has several comments that I think end up related to this so I will go back through and review them now.
