Adds two RPC tests for the generatetoaddress RPC, one in the wallet, and one when the wallet is disabled.
The wallet RPC Test mines Bitcoin to another node's address and checks that that node has received the Bitcoin.
The RPC test without the wallet mines Bitcoin to an arbitrary address and checks that it works. It then mines to an arbitrary invalid address and checks that that fails.
This RPC test will test both the activation mechanism of the first versionbits soft fork as well as testing many code branches of the consensus logic for BIP's 68, 112, and 113.
If ZMQ is enabled, check whether it's installed before running ZMQ tests.
If it isn't, disable ZMQ and print a warning.
Also add dependency info to test docs, so users know ZMQ is required
before running tests, and so they know how to install it.
When following the build instructions before this change then trying
to run the RPC tests, a unix user would get an error when python
tried to import zmq.
There may be other dependencies that should be added to the docs,
particularly ones for non-unix systems. This is the only unlisted
dependency I encountered using linux.
Add "bip125-replaceable" output field to listtransactions and gettransaction
which indicates if an unconfirmed transaction, or any unconfirmed parent, is
signaling opt-in RBF according to BIP 125.
In rpc-tests.py, don't override BITCOIND and BITCOINCLI if they're
already set. Makes it possible to run the tests with either another tree
or the GUI.
