verifier: fix logic bug. after reorg, some verifs were not undone
...
after a reorg, in a many fork/orphan chains scenario,
we would sometimes not undo SPV for enough blocks
functions in blockchain.py somewhat based on kyuupichan/bitcoinX@5126bd15ef

blockchain: fix difficulty retarget
...
"target" is a 256 bit int, but the "bits" field in the block headers
that is used to represent target is only 32 bits.
We were checking PoW against the untruncated target value, which is a
slightly larger value than the one that can actually be represented,
and hence we would have accepted a slightly lower difficulty chain
than what the consensus requires.

network: auto-switch servers to preferred fork (or longest chain)
...
If auto_connect is enabled, allow jumping between forks too.
(Previously auto_connect was only switching servers on a given fork,
not across forks)
If there is a preferred fork set, jump to that (and stay);
if there isn't, always jump to the longest fork.
