bitcoin/signature: BIP143 signature support.
We hand in the witness_script: if non-NULL, we use BIP143-style
signature hash creation.

bitcoin/tx: sha256_tx_for_sig() takes sighash flag.
That way it can assert (as we only support SIGHASH_ALL).

bitcoin/tx: (optional) input amount.
We need this for signing segwitness txs. Unfortunately, we don't have it
for transactions we received as hex, only ones we created; to make this safe
we use a pointer which is NULL if we don't know, and those will crash if
we try to sign or check their sigs.

Remove Alpha support.
I had already disabled it, and this clears the decks for Segregated Witness

locktime: nice abstractions for absolute and relative locktimes.
I got confused navigating these, especially since Alpha and Bitcoin
have diverged (BIP68 was proposed after Elements Alpha).

BIP68 support (nSequence enforcement)
The latest version of the BIP doesn't use inversion, but does use
bitshifts.
It also uncovered a bug in the test scripts: the block timestamps
creep forward when we generate large numbers of blocks (UpdateTime
insists it be > GetMedianTimePast() so it's valid). We need to take
this into account when waiting for the median to move (reduced it from
60 to 30 seconds, since that adds about 14 seconds).
