de670bd5b2 check for 0 length strings in pubkey parser.
We check length later, but we assumed it was always 1 bytes long. Not
always the case. I'm a little depressed that this bug was there.

dab2a7cb0f Don't possibly dereference bad signatures in OP_CHECKMULTISIG.
We do all the preprocessing in one loop. Fixes a bug introduced a while ago to
handle invalid signatures. Found by more tests from bitcoind.

c8332cc9a7 Correct num expected inputs calc for multisig.
This commit corrects the number of expected inputs for a multi-sig script
to include the additional item that is popped from the stack due to the
OP_CHECKMULTISIG consensus bug (which is required and properly performed).

Note this issue did NOT affect the consensus critical code and hence would
not cause a chain fork.  It did however, cause standard p2sh multisig txns
to be rejected from the mempool as nonstandard.

The tx rejected as non-standard which prompted this was spotted by
@mbelshe on IRC.

93140802ba Improve non-standard tx error message.
This commit removes the word "only" from the non-standard transaction
error message when the number of items on the stack does not match the
number of expected items.

This was suggested by @mbelshe.

c1a6e47f38 Conditionals must not straddle two scripts.
Found by tests dhill is working on. We checked that ifs were closed at the end

b661dd3693 Convert block manager block handler to pure FIFO.
Rather than having a separate query channel for the block manager, use the
same channel so the block handler acts as a pure FIFO queue.  This
prevents possible starvation of query related messages.

1676ecd7a6 Export CheckConnectBlock function.
This commit makes a slight variant of the existing checkConnectBlock
function available to external callers.  The new exported version checks
if the passed block will connect to the end of the current main chain.

In order to support this, a few other small modifications have been made
to the initial index generation and the existing checkConnectBlock since
it previously made some assumptions about the state of genesis block which
can no longer be assumed due accepting blocks from callers directly.

Also, add a quick test to ensure the new function fails when checking if
the genesis block will connect again when it's already inserted.

a7d5b365b1 Retain order when processing client notifications.
This change modifies the RPC server's notifiation manager from a
struct with requests, protected by a mutux, to two goroutines.  The
first maintains a queue of all notifications and control requests
(registering/unregistering notifications), while the second reads from
the queue and processes notifications and requests one at a time.

Previously, to prevent slowing down block and mempool processing, each
notification would be handled by spawning a new goroutine.  This lead
to cases where notifications would end up being sent to clients in a
different order than they were created.  Adding a queue keeps the
order of notifications originating from the same goroutine, while also
not slowing down processing while waiting for notifications to be
processed and sent.

2a42cc134f Lower min transaction relay fee to 1000 satoshi.
This mirrors a recent change in the reference implementation.  Since the
vast majority of the network still uses it and transactions which aren't
considered standard won't be relayed, the rules for standard transactions
need to be kept consistent.

Ideally this should be handled via floating fees, but we're rather limited
until we have miner support and a larger network share so the probability
of a transaction being relayed and confirmed is high.

Closes #100.

b041971ca8 Export CalcNextRequiredDifficutly function.
This commit exports a new variant of the existing internal
calcNextRequiredDifficulty function which calculates and returns the next
required difficulty for a block after the end of the current best chain
based on the difficulty retarget rules.

In order to support the exported function the internal one was slightly
modified to accept the block timestamp instead of an entire block since
the timestamp is all that is needed and the caller of the exported
function might next have a full block yet.

ec641751a8 Change BuildMerkleTreeStore to accept transactions.
This commit modifies the BuildMerkleTreeStore function to accept a slice
of btcutil.Tx transactions as opposed to a full block.  This allows more
flexibility when calculating merkle roots since a full block may not be
created yet (particularly when generating blocks that need to be solved in
mining).

Previously, the BuildMerkleTreeStore function accepted a btcutil.Block
because originally the block itself cached the transaction hashes and it
was necessary to have access to the block to make use of the cached
transactions.  However, the code has since been improved such that it
caches transaction hashes directly in each btcutil.Tx.  This means the
code can remain as efficient as before while allowing the individual
transacitons to be passed.
