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.
Also introduce UniValueType
UniValueType is a wrapper for UniValue::VType which allows setting
a typeAny flag. This flag indicates the type does not matter.

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.
In my ever-growing list of test failures, I was seeing this one intermittently.

```
After digging into the test, I found that the code is waiting 10 seconds for blk00000.dat to be deleted, and then throwing this failure if it still exists after 10 seconds.
I increased this amount, had the script print the actual time taken, and ran the test a few more times. The time taken ranged between 8 to 12 seconds. So, I feel that this timeout is too short.
After changing the timeout to 30 seconds, the test passes consistently.
