fdda3c5085 Use Equihash for Proof-of-Work 
The main and test networks are configured to use parameters that are currently
low-memory but usable with the basic solver; they will be increased once the
solver is optimised. The regtest network is configured to have extremely low
memory usage for speed.

Note that Bitcoin's double-hasher is used for the difficulty check. This does
not match the paper, but is simpler than changing the block header
serialization. Single hashing is kept for the EquiHash solver because there is
no requirement on execution time there, only on memory usage.

AcceptBlock will no longer process an unrequested block, unless it has not
been previously processed and has more work than chainActive.Tip()

27ce808fb5 tests: Error when setgenerate is used on regtest 
Ever since #5957 there has been the problem that older RPC test cases
(as can be found plenty in open pulls) use setgenerate() on regtest,
assuming a different interpretation of the arguments. Directly
generating a number of blocks has been split off into a new method
`generate` - however using `setgenerate` with the previous arguments will
result in spawning an unreasonable number of threads, and well, simply
not work as expected without clear indication of the error.

Add an error to point the user at the right method.

Rebased by @laanwj:

- update for RPC methods added since 84d13ee: setmocktime,
  invalidateblock, reconsiderblock. Only the first, setmocktime, required a change,
  the other two are thread safe.

18379875bf Optimize -regtest setgenerate block generation 
Speed up generating blocks in regression test mode, by moving
block-creating and nonce-finding directly into the setgenerate
RPC call (instead of starting up a mining thread and waiting for
it to find a block).

This makes the forknotify RPC test three times quicker, for
example (10 seconds runtime instead of 30 seconds, assuming
the initial blockchain cache is already built).
