This change improves clock management for zcashd by ensuring
that all clock methods (obtaining seconds, milliseconds, and
microseconds since the epoch) agree under testing conditions
using `-mocktime`, and also adds a feature that allows tests
to specify an offset to the system clock; this is useful to
allow comprehensive testing of the "timejacking attack mitigation"
consensus rules.
Previously we only required synchronization points where blocks were
sent between nodes; now we need them between action and query operations
on the same node, because wallet notification of mined blocks no longer
occurs in real-time.
Strictly speaking this is not a true deduplication; the test output will be
slightly different (due to inconsistent print statements) but I think this is
close enough.
- Add height parameter to z_importkey to reduce rescan range
- Change semantics of rescan parameter, so users can explicitly force a rescan
for existing keys.
