catbref 94d18538d8 More work on cross-chain trading, including API calls.
Added API calls to aid Qortal-side of cross-chain trading.
POST /crosschain/build - for building Qortal AT
POST /crosschain/tradeoffer/recipient - for sending trade partner/recipient to AT
POST /crosschain/tradeoffer/secret - for sending secret to AT
DELETE /crosschain/tradeoffer - for cancelling AT

More fixes regarding Blocks processing/orphaning ATs.
More fixes regarding sending/receiving blocks containing AT data.
AT-related fix to genesis block.

Improved cross-chain trading AT code, removing offer-mode timeout
and replacing that with allowing AT creator to cancel offer/end AT
by sending AT the creator's own address as trade partner/recipient.
After all, they're not going to trade with themselves.

Added assertion to check BTCACCT.CODE_BYTES_HASH matches compiled code hash.

Added cross-chain AT's 'mode' for easier diagnosis, either OFFER or TRADE.

We can't use AT's signature to generate AT address because address is needed
before DEPLOY_AT transaction is signed. So we use a hash of signature-less
transaction bytes.

Corresponding changes to tests.
