protocol: add checks for top block hard fork version
We won't even talk to a peer which claims a wrong version
for its top block. This will avoid syncing to known bad
peers in the first place.
Also add IP fails when failing to verify a block.

blockchain: skip checking tx semantics in embedded block hash range
If the txes are bad, this'll be picked up by the block hash mismatch
since the tx merkle root is part of the block hash.

blockchain: ensure all blocks get their longhash precalculated
If the number of blocks to check was not a multiple of the
number of preparation threads, the last few blocks would
not be included in the threaded long hash calculation.
Those would still get calculated when the block gets added
to the chain, however, so this was only a tiny performance
hit, rather than a security bug.

Move txpool to the database
Integration could go further (ie, return_tx_to_pool calls should
not be needed anymore, possibly other things).

poolstate.bin is now obsolete.

Add intervening v5 fork for increased min block size
Minimum mixin 4 and enforced ringct is moved from v5 to v6.
v5 is now used for an increased minimum block size (from 60000
to 300000) to cater for larger typical/minimum transaction size.

The fee algorithm is also changed to decrease the base per kB
fee, and add a cheap tier for those transactions which we do
not care if they get delayed (or even included in a block).

core: dynamic fee algorithm from ArticMine
The fee will vary based on the base reward and the current
block size limit:

fee = (R/R0) * (M0/M) * F0

R: base reward
R0: reference base reward (10 monero)
M: block size limit
M0: minimum block size limit (60000)
F0: 0.002 monero

Starts applying at v4

wallet: select part of the fake outs from recent outputs
25% of the outputs are selected from the last 5 days (if possible),
in order to avoid the common case of sending recently received
outputs again. 25% and 5 days are subject to review later, since
it's just a wallet level change.

rct: rework the verification preparation process
The whole rct data apart from the MLSAGs is now included in
the signed message, to avoid malleability issues.

Instead of passing the data that's not serialized as extra
parameters to the verification API, the transaction is modified
to fill all that information. This means the transaction can
not be const anymore, but it cleaner in other ways.

Fake outs set is now decided by the wallet
This plugs a privacy leak from the wallet to the daemon,
as the daemon could previously see what input is included
as a transaction input, which the daemon hadn't previously
supplied. Now, the wallet requests a particular set of
outputs, including the real one.

This can result in transactions that can't be accepted if
the wallet happens to select too many outputs with non standard
unlock times. The daemon could know this and select another
output, but the wallet is blind to it. It's currently very
unlikely since I don't think anything uses non default
unlock times. The wallet requests more outputs than necessary
so it can use spares if any of the returns outputs are still
locked. If there are not enough spares to reach the desired
mixin, the transaction will fail.

new unlocked parameter to output_histogram
This constrains the number of instances of any amount
to the unlocked ones (as defined by the default unlock time
setting: outputs with non default unlock time are not
considered, so may be counted as unlocked even if they are
not actually unlocked).

Convey tx verification failure reasons to the RPC client
This allows appropriate action to be taken, like displaying
the reason to the user.

Do just that in simplewallet, which should help a lot in
determining why users fail to send.

Also make it so a tx which is accepted but not relayed is
seen as a success rather than a failure.

New RPC and daemon command to get output histogram
This is a list of existing output amounts along with the number
of outputs of that amount in the blockchain.

The daemon command takes:
- no parameters: all outputs with at least 3 instances
- one parameter: all outputs with at least that many instances
- two parameters: all outputs within that many instances

The default starts at 3 to avoid massive spamming of all dust
outputs in the blockchain, and is the current minimum mixin
requirement.

An optional vector of amounts may be passed, to request
histogram only for those outputs.

blockchain: for v3, require miner tx to have well behaved outs

the cracks as it doesn't go through the main tx verification
since it doesn't get added to the pool.

improvement in clarity and design have been noted, as well as cruft to
be removed.  These changes are not reflected in this commit both to

1642be242d minor bugfixes and refactoring
- Blockchain should store if it's running on testnet or not

- moved loading compiled-in block hashes to its own function for clarity

- on handle_get_objects, should now correctly return false if a block's
transactions are missing

- replace instances of BOOST_FOREACH with C++11 for loops in Blockchain.
