The solve tests are all tunable so that we can balance execution time
with test coverage. A longer solve will test more random programs and it
will test more of the nonce increment function, minor benefits at the
cost of much more CPU.
The starting nonce in solve_effort1k_aa_41_01 was set so that we would
exercise a rollover in bit 7 of the nonce increment before the full
width rollover, but this wasn't a particularly helpful place to test
and certainly not worth the 13+ seconds it takes on my machine.
This patch bumps the starting nonce to a value much closer to the
target, and still including the full-width rollover.
Brings solve_effort1k_aa_41_01 down from 13.2 seconds to 0.5 sec for me.

This test had one large function for all the verifies and one for all
the solves. The solve test was slow enough to be a bottleneck,
documented in ticket #991.
This patch splits the existing tests up in to one labeled function per
solve or verify configuration.

This adds a new tor-hspow crate with the first layers of support in
place for onion service client puzzles as described in Proposal 327.
The API here is experimental, and it's currently only implementing
the self-contained parts of the client puzzle. So, it can verify and
solve puzzles, but it has no event loop integration or nonce replay
tracking or prioritization code yet. These things seem like they would
eventually live in the same crate.
