19880b177e Optimize InsertBlock with cached tx hashes.
This commit optimizes InsertBlock slightly by using the cached transaction
hashes instead of recomputing them.  Also, while here, use the
ShaHash.IsEqual function to do comparisons for consistency.

This is ongoing work towards conformal/btcd#25.

ok @drahn.

7d8bb5ab4c Add --cpuprofile option.
This commit provides a new --cpuprofile flag that can be used to specify a
file path to write CPU profile data into.  The resulting profile can then be
consumed by the 'go tool pprof' command.

1aa65e6863 Correct and improve SIGINT (Ctrl+C) handling.
Since the main SIGINT handler is running as a goroutine, the main
goroutine must be kept active long enough for it to finish or it will be
nuked when the main goroutine exits.  This commit makes that happen by
slightly modifying how it waits for shutdown.

Rather than having the main goroutine only wait for the server to
shutdown, there is now a shutdown channel that is used to signal the main
goroutine to shutdown for all cases such as a graceful shutdown, a
scheduled shutdown, an RPC stop, or a SIGINT.

While here, also add a few prints to indicate a SIGINT was received and
the shutdown progress.

b6e4ae4441 Optimize duplicate transaction input check.
Profiling showed the duplicate transaction input check was taking around
6% of the total CheckTransactionSanity processing time.  This was largely
due to using fmt.Sprintf to generate the map key.

This commit modifies the check instead to use the actual output as a map
key.

The following benchmark results show the difference:

Before: BenchmarkOldDuplicatInputCheck    100000     21787 ns/op
After:  BenchmarkNewDuplicatInputCheck   2000000       937 ns/op

Closes #2

261e61f8ee Vastly optimize the MRU inventory handling.
Profiling showed the MRU inventory handling was taking 5% of the total
block handling time.  Upon inspection this is because the original
implementation was extremely inefficient using iteration to find the
oldest node for eviction.

This commit reworks it to use a map and list in order to achieve close to
O(1) performance for lookups, insertion, and eviction.

The following benchmark results show the difference:

Before: BenchmarkMruInventoryList          100     1069168 ns/op
After:  BenchmarkMruInventoryList     10000000         152 ns/op

Closes #21

24a5645fce Update for recent btcchain tx script val change.
The ValidateTransactionScripts was recently changed to accept script flags
which pass through to the script engine in order to control its validation
behavior.  This commit modifies the transaction memory pool script
validation code for this change and additionally adds the new flag to
perform canonical signtaure checking.

8eead5217d Add flag bitmask to NewScript for canonical sig checks.
This removes the bip16 bool from NewScript and adds it to flags (with
the constant ScriptBip16), and also adds a new flag,
ScriptCanonicalSignatures, which will call btcec.ParseDERSignature
parsing a signature during an Execute.  This is needed to emulate
bitcoind behavior, as bitcoind performs canonical signature validation
(DER format) in some places (like mempool acceptance) but not others
(like block validation).

Updated tests and test coverage file to reflect changes.

98ac46b37d Add ParseDERSignature.
This change adds an additional signature parsing function which
performs additional checks to verify the signature is serialized in a
valid DER (and thus, unique) format, instead of allowing the less
strict BER signatures that ParseSignature will happily accept.

Added additional tests and updated test coverage to reflect changes.

Code isn't fully tested yet so may well still be buggy in the type conversions.

This commit modifies the ValidateTransactionScripts API to accept the
recently added ScriptFlags from btcscript.  This provides flexibility to
the caller to choose validation behavior based on those new flags.

5cc32bbfc7 Add bounds checking to all variable length allocs.
Several of the bitcoin data structures contain variable length entries,
many of which have well-defined maximum limits.  However, there are still
a few cases, such as variable length strings and number of transactions
which don't have clearly defined maximum limits.  Instead they are only
limited by the maximum size of a message.

In order to efficiently decode messages, space is pre-allocated for the
slices which hold these variable length pieces as to avoid needing to
dynamically grow the backing arrays.  Due to this however, it was
previously possible to claim extremely high slice lengths which exceed
available memory (or maximum allowed slice lengths).

This commit imposes limits to all of these cases based on calculating
the maximum possible number of elements that could fit into a message
and using those as sane upper limits.

The variable length string case was found (and tests added to hit it) by
drahn@ which prompted an audit to find all cases.

618b885e9e Notify wallets of mined transactions.
This change allows btcwallet to keep a pool of transactions that have
not yet been mined into a block, notifying wallet when transactions
are mined, as well as introducing a new way to send the
btcd:blockconnected notification with wallet-specific information as
part of the same notification.  When a transaction is sent using the
RPC call 'sendrawtransaction', a notification request will be
automatically registered with the connected wallet (if using
websockets) to notify the wallet when the transaction first appears in
a block.

To perform this notification, and to avoid requiring wallets from
waiting for seperate mined tx notifications (and resend after a
timeout) or from sending an additional tx mined request for every tx
in the pool after each new block, the blockconnected notification is
now created seperately for each wallet.  If the notified wallet has
sent a transaction, an additional JSON field "minedtxs" will include
an array of transaction IDs that the wallet has created and which are
included in the new block.

This new unique blockconnected notification can also be used for
additional notifications that may happen each new block in the future,
and to cut down on existing notification handlers in btcwallet, such
as for transactions to a watched address.

2bb8c5d5cc Bring back default redirect for profiling.

5a4772bdc6 Change the RPC server to use it's own Muxer.
Rather than relying on the http package's DefaultServeMux for the RPC
server, create a unique mux specifically for the RPC server.  This ensures
things, such as the http profiling handlers, do not commingle.
