Including BIP143 P2WSH examples by jl2012.

Contains refactorings by Eric Lombrozo.
Contains fixup by Nicolas Dorier.
Contains cleanup of CInv::GetCommand by Alex Morcos

- Replace NOP3 with CHECKSEQUENCEVERIFY (BIP112)
<nSequence> CHECKSEQUENCEVERIFY -> <nSequence>
- Fails if txin.nSequence < nSequence, allowing funds of a txout to be locked for a number of blocks or a duration of time after its inclusion in a block.
- Pull most of CheckLockTime() out into VerifyLockTime(), a local function that will be reused for CheckSequence()
- Add bitwise AND operator to CScriptNum
- Enable CHECKSEQUENCEVERIFY as a standard script verify flag
- Transactions that fail CSV verification will be rejected from the mempool, making it easy to test the feature. However blocks containing "invalid" CSV-using transactions will still be accepted; this is *not* the soft-fork required to actually enable CSV for production use.

Update the unittest that is meant to catch a transaction that is invalid
because it has a null input. The old test failed not because of that
but because it was considered a coinbase with too large script. This is
already checked with a different test, though.
The new test is *not* a coinbase since it has two inputs, but one of
them is null. This really checks the corresponding code path in
CheckTransaction.

Add test cases for DERSIG flag enforcement against transactions.

c5c1edf Fix spelling mistake in -> if. (Mark Friedenbach)
e846b2a Correct a possibly intentional pun that is nevertheless hard to read: "two times of nLockTime." What is meant is that there are two kinds, or categories of nLockTime. (Mark Friedenbach)

Four cases included:
* The CLTV operand type mismatches the tx locktime. In the script it is
1 (interpreted as block height), but in the tx is 500000000
(interpreted as date)
* The stack is empty when executing OP_CLTV
* The tx is final by having only one input with MAX_INT sequence number
* The operand for CLTV is negative (after OP_0 OP_1 OP_SUB)

<nLockTime> CHECKLOCKTIMEVERIFY -> <nLockTime>
Fails if tx.nLockTime < nLockTime, allowing the funds in a txout to be
locked until some block height or block time in the future is reached.
Only the logic and unittests are implemented; this commit does not have
any actual soft-fork logic in it.
Thanks to Pieter Wuille for rebase.
Credit goes to Gregory Maxwell for the suggestion of comparing the
argument against the transaction nLockTime rather than the current
time/blockheight directly.

This commit adds some tests to the script_valid.json and tx_invalid.json
data which exercise more edge conditions that are not currently being
tested.

OP_CODESEPARATOR is an actual executed instruction, not a declarative
thing, so if it's wrapped in an OP_IF it can be turned off.
Using this to implement Rivest's Paywords is left as an exercise for the
reader.

This is a source of transaction mutability as the dummy value was
previously not checked and could be modified to something other than the
usual OP_0 value.

Previously only P2SH could be set.

the mempool instance.
Removed AreInputsStandard from CTransaction, made it a regular function in main.
Moved CTransaction::GetOutputFor to CCoinsViewCache.
Moved GetLegacySigOpCount and GetP2SHSigOpCount out of CTransaction into regular functions in main.
Moved GetValueIn and HaveInputs from CTransaction into CCoinsViewCache.
Moved AllowFree, ClientCheckInputs, CheckInputs, UpdateCoins, and CheckTransaction out of CTransaction and into main.
Moved IsStandard and IsFinal out of CTransaction and put them in main as IsStandardTx and IsFinalTx. Moved GetValueOut out of CTransaction into main. Moved CTxIn, CTxOut, and CTransaction into core.
Added minimum fee parameter to CTxOut::IsDust() temporarily until CTransaction is moved to core.h so that CTxOut needn't know about CTransaction.
