* Reduce DEFAULT_FALLBACK_FEE to 1,000,000 Koinu. Note this by itself has no effect as the required fee is higher.
* Reduce wallet minimum fees to 0.01 DOGE
* Update DEFAULT_DUST_LIMIT
* Revise derived values after updating recommended fees
* Remove fee rounding from RPC tests
* Revert tests back to Bitcoin originals where possible
* Enable full block tests
* Fix invalidblocktest
* Move watch only address funding to immediately before it's used, so node 0 doesn't spend the output before it checks it later.
* Fix `fundrawtransaction` tests and sanitize fee calculation at the same time
* Correct resolution of chain parameters when validating tx inputs, especially from previous coinbase transactions
* Set block versions on full block tests so that the generated blocks are AuxPoW compatible
Previously various user-facing strings have used inconsistent currency units "BTC",
"btc" and "bitcoins". This adds a single constant and uses it for each reference to
the currency unit.
Also adds a description of the unit for --maxtxfee, and adds the missing "amount"
field description to the (deprecated) move RPC command.
