2019-10-30refactor: Replace all uses of boost::optional with our own Optional typeWladimir J. van der Laan
After this: - `boost::optional` is no longer used directly (only through `Optional` which is an alias for it) - `boost/optional.hpp` is only included in one place
2019-10-29[validation] Add CValidationState subclassesJohn Newbery
Split CValidationState into TxValidationState and BlockValidationState to store validation results for transactions and blocks respectively.

2019-04-09[build] Move policy settings to new src/policy/settings unitJohn Newbery
This moves the following policy settings functions and globals to a new src/policy/settings unit in lib_server: - `incrementalRelayFee` - `dustRelayFee` - `nBytesPerSigOp` - `fIsBareMultisigStd` These settings are only required by the node and should not be accessed by other libraries.
2019-03-22Move g_is_mempool_loaded into CTxMemPool::m_is_loadedBen Woosley
So the loaded state is explicitly mempool-specific.

Update: this PR now corrects usage of max ancestors / max descendants, including calculating the correct max descendant value, as advertised for the two limits. ~~This change also makes `nMaxAncestors` signed, as the replacement method will return `-1` for "not in the mempool", which is different from "0", which means "no ancestors/descendants in mempool".~~ ~~This is a subset of #12257.~~ Tree-SHA512: aa59c849360542362b3126c0e29d44d3d58f11898e277d38c034dc4b86a5b4500f77ac61767599ce878c876b5c446fec9c02699797eb2fa41e530ec863a00cf9

2018-06-11mempool: Fix max descendants checkKarl-Johan Alm
The chain limits check for max descendants would check the descendants of the transaction itself even though the description for -limitdescendantcount says 'any ancestor'. This commit corrects the descendant count check by finding the top parent transaction in the mempool and comparing against that.
2018-06-11mempool: Add explicit max_descendantsKarl-Johan Alm
TransactionWithinChainLimits would take a 'limit' and check it against ascendants and descendants. This is changed to take an explicit max ancestors and max descendants value, and to test the corresponding value against its corresponding max.

b55555d rpc: Add testmempoolaccept (MarcoFalke) Pull request description: To check if a single raw transaction makes it into the current transaction pool, one had to call `sendrawtransaction`.
