07704c1 Add some tests for getchaintxstats (Akio Nakamura)
3336676 Fix getchaintxstats() (Akio Nakamura)
Pull request description:
1. calculate nblocks more adaptive.
-> set default nblocks to min (blocks for 1 month, target block's height - 1)
-> before PR: if not specify nblocks-parameter, illegal parameter error will happen when target block height is below nblocks.
2. correct error message.
-> nblocks accepts [1 .. block's height -1] . so add a word "-1".
3. add check 0-divide.
-> if nTimeDiff = 0 then use UniValue(UniValue::VNULL) and returns {... "txrate": null} .
-> before PR: if nTimeDiff = 0 then returns {... "txrate":} and bitcoin-cli cannot handle the response.

Almost all test scripts currently need to override the __init__()
method. When they do that they need to call into super().__init__() as
the base class does some generic initialization.
This commit makes the base class __init__() call into set_test_params()
method. Individual test cases can override set_test_params() to setup
their test parameters.
Separates the act of creating a TestNode object from starting the node.
The test_framework now keeps track of its list of TestNodes, and test
writers can call start_node() and stop_node() without having to update
the self.nodes list.
TestNode is a class responsible for all state related to a bitcoind node
under test. It stores local state, is responsible for tracking the
bitcoind process and delegates unrecognised messages to the RPC
connection.
This commit changes start_nodes and stop_nodes to start and stop the
bitcoind nodes in parallel, making test setup and teardown much faster.
This commit moves functions start_node, start_nodes, stop_node and
stop_nodes functions into the BitcoinTestFramework class. It also moves
the bitcoind_processes dict and coverage variables into BitcoinTestFramework.
This makes the following changes:
* In undo data and the chainstate database, the transaction nVersion
field is removed from the data structures, always written as 0, and
ignored when reading.
* The definition of hash_serialized in gettxoutsetinfo is changed to no
longer incude the nVersion field. It is renamed to hash_serialized_2
to avoid confusion. The new definition also includes transaction
height and coinbase information, as this information was missing
before.
This depends on having a CHashVerifier-based undo data checksum
verifier.
Apart from changing the definition of serialized_hash, downgrading
after using this patch is supported, as no release ever used the value
of nVersion field in UTXO entries.
