fix misbehaving simulnet fastsync test (#1227)
* fix misbehaving simulnet fastsync test
cleanup redundant cutoff vs bitmap params is rewind and check_compact

* make sure we do not verify full kernel history on a writeable txhashset extension
rework simulnet simulate_fast_sync test to be more robust

* fixup store tests

* sleep for a bit longer to give nodes time to update
their sync_state correctly

* tweak timing of simulate_block_propagation

Fix kernel history verification (#1218)
Only rewind kernels to avoid requiring proper bitmap extraction. Also avoids maintaining bitmap data for kernels by introducing a "prunable" flag on PMMR backend.

Replace rm_log with leaf_set (compact bitmap) (#1147)
* only store leaves in rm_log

* cleanup

* commit

* add failing test to cover case where we compact
an already compacted data file

* fix the logic for pruning the data file

* rm_log only contains leaves
prunelist only contains non-leaf subtree roots

* cleanup

* commit

* bitmap impl running in parallel

* rustfmt

* this is better - rewind unremoves outpu pos spent by rewound inputs

* commit

* commit

* pass bitmap around when rewinding

* store and retrieve input bitmap per block from the db

* Replace the RemoveLog with the UTXO set.

* utxo set starting to pass tests

* stuff works...

* split store types out
added some tests to compare the performance of the rm_log and the proposed utxo_set

* pull prune_list out into standalone file

* cleanup, get rid of unused height param

* cleanup and add doc comments

* add support for migrating rm_log to utxo_set

* take snapshot of utxo file during fast sync
implement migration of rm_log -> utxo_set

* rename rewound_copy to snapshot

* fixup pmmr tests to reflect cutoff_pos

* cleanup unused import

* check_compact needs to rewind the utxo_set as appropriate

* fix pool tests

* fixup core tests

* cache block_input_bitmaps via LruCache in store

* cache block header on initial write to db

* rename utxo_set -> leaf_set
and remove references to "spent" in grin_store

* better document the rewind behavior
