This improves error reporting if `JSONRPCException` is not specifically caught
and ends up in Python's default backtrace handler.
Before:
```
Traceback (most recent call last):
File "/.../projects/bitcoin/bitcoin/qa/rpc-tests/test_framework/authproxy.py", line 153, in __call__
raise JSONRPCException(response['error'])
test_framework.authproxy.JSONRPCException
```
After:
```
Traceback (most recent call last):
File "/.../projects/bitcoin/bitcoin/qa/rpc-tests/test_framework/authproxy.py", line 152, in __call__
raise JSONRPCException(response['error'])
test_framework.authproxy.JSONRPCException: Unknown named parameter random (-8)
```
waitfornewblock waits until a new block is received, or the timeout expires, then
returns the current block height/hash.
waitforblock waits for a specific blockhash, or until the timeout expires, then
returns the current block height/hash. If the target blockhash is the current
tip, it will return immediately.
waitforblockheight waits until the tip has reached a certain height or higher,
then returns the current height and hash.
waitforblockheight is used to avoid polling in the rpc tests.

has a helper for adding witness commitments to blocks, and script
has a function to calculate hashes for signature under sigversion

Add a setting ensure_ascii to AuthServiceProxy. This setting,
defaulting to True (backwards compatible),
is passed through to json.dumps. If set to False, non-ASCII characters
>0x80 are not escaped. This is useful for testing server
input processing, as well as slightly more bandwidth friendly in case of
heavy unicode usage.
Previously these functions would infinitely loop if sync failed;
now they have a default timeout of 60 seconds, after which an
AssertionError is raised.
sync_blocks() has also been improved and now compares the tip
hash of each node, rather than just using block count.
