The Header MMR (One MMR To Rule Them All) (#1716) (#1747)

Browse Source 
* header MMR in use within txhashset itself
works with fast sync
not yet in place for initial header sync

* add the (currently unused) sync_head mmr

* use sync MMR during fast sync
rebuild header MMR after we validate full txhashset after download

* support missing header MMR (rebuild as necessary) for legacy nodes

* rename to HashOnly

* cleanup backend.append()

* simplify vec_backend to match simpler append api
