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).

add a --max-concurrency flag
It sets the max number of threads to use for a parallel job.
This is different that the number of total threads, since monero
binaries typically start a lot of them.

blockchain: add missing overflow check for already generated coins
When reaching the tail emission phase, the amount of coins will
eventually go over MONEY_SUPPLY, overflowing 64 bits. There was
a check added to blockchain_storage, but this was not ported to
the blockchain DB version.

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
This was meant to go in v2, but the miner tx slipped through
the cracks as it doesn't go through the main tx verification
since it doesn't get added to the pool.

Move checkpoint functions into checkpoints class
The functions in src/cryptonote_core/checkpoints_create.{h,cpp} should
be member functions of the checkpoints class, if nothing else for the
sake of keeping their documentation together.

This commit covers moving those functions to be member functions of the
checkpoints class as well as documenting those functions.

Updated documentation for blockchain.*
All functions are now documented in doxygen format.  Comments have been
updated to reflect the current state of the code.  Many areas for
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
allow time for comment and to keep commits organized by purpose.

Blockchain: Omit verbose time stats messages by default
This is already the default for the daemon, but by checking a command
line argument and calling a Blockchain member function setter.

Initialize the variable to false so it's not dependent on an external
command-line argument check. This allows utilities like
blockchain_import to have a reasonable default without code changes.

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.
