blockchain_db: remove unused get_output_key variant

db: store cumulative rct output distribution in the db for speed
This gets rid of the temporary precalc cache.

Also make the RPC able to send data back in binary or JSON,
since there can be a lot of data

This bumps the LMDB database format to v3, with migration.

34cb6b4b70 add --regtest and --fixed-difficulty for regression testing
on_generateblocks RPC call combines functionality from the on_getblocktemplate and on_submitblock RPC calls to allow rapid block creation. Difficulty is set permanently to 1 for regtest.
Makes use of FAKECHAIN network type, but takes hard fork heights from mainchain
Default reserve_size in generate_blocks RPC call is now 1. If it is 0, the following error occurs 'Failed to calculate offset for'.
Queries hard fork heights info of other network types

10013e94 Protect node privacy by proper filtering in restricted-mode RPC answers (binaryFate)

10013e9434 Protect node privacy by proper filtering in restricted-mode RPC answers
This patch allows to filter out sensitive information for queries that rely on the pool state, when running in restricted mode.
This filtering is only applied to data sent back to RPC queries. Results of inline commands typed locally in the daemon are not affected.
In practice, when running with `--restricted-rpc`:
* get_transaction_pool will list relayed transactions with the fields "last relayed time" and "received time" set to zero.
* get_transaction_pool will not list transaction that have do_not_relay set to true, and will not list key images that are used only for such transactions
* get_transaction_pool_hashes.bin will not list such transaction
* get_transaction_pool_stats will not count such transactions in any of the aggregated values that are computed

The implementation does not make filtering the default, so developers should be mindful of this if they add new RPC functionality.
Fixes #2590.

track double spending in the txpool
Transactions in the txpool are marked when another transaction
is seen double spending one or more of its inputs.
This is then exposed wherever appropriate.

Note that being marked with this "double spend seen" flag does
NOT mean this transaction IS a double spend and will never be
mined: it just means that the network has seen at least another
transaction spending at least one of the same inputs, so care
should be taken to wait for a few confirmations before acting
upon that transaction (ie, mostly of use for merchants wanting
to accept unconfirmed transactions).

Toggle SAFE syncmode on and off automatically
If monerod is started with default sync mode, set it to SAFE after
synchronization completes. Set it back to FAST if synchronization
restarts (e.g. because another peer has a longer blockchain).

If monerod is started with an explicit sync mode, none of this
automation takes effect.

blockchain_db: do not throw on expected partial results getting keys
When scanning for outputs used in a set of incoming blocks,
we expect that some of the inputs in their transactions will
not be found in the blockchain, as they could be in previous
blocks in that set. Those outputs will be scanned there at
a later point. In this case, we add a flag to control wehther
an output not being found is expected or not.

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.

core: faster find_blockchain_supplement
Since this queries block heights for blocks that may or may not
exist, queries for non existing blocks would throw an exception,
and that would slow down the loop a lot. 7 seconds to go through
a 30 hash list.

Fix this by adding an optional return block height to block_exists
and using this instead. Actual errors will still throw an
exception.

This also cuts down on log exception spam.

move the rct commitments to the output_amounts database
Since these are needed at the same time as the output pubkeys,
this is a whole lot faster, and takes less space. Only outputs
of 0 amount store the commitment. When reading other outputs,
a fake commitment is regenerated on the fly. This avoids having
to rewrite the database to add space for fake commitments for
existing outputs.

This code relies on two things:

- LMDB must support fixed size records per key, rather than
per database (ie, all records on key 0 are the same size, all
records for non 0 keys are same size, but records from key 0
and non 0 keys do have different sizes).

- the commitment must be directly after the rest of the data
in outkey and output_data_t.

132c666f67 Update schema for "tx_outputs" to use array containing amount output indices
This speeds up wallet refresh by directly retrieving a tx's amount output indices.

It removes the indirection and walking the amount output duplicate list
for every amount in each requested tx.

"tx_outputs" is used by:
Amount output indices are needed for wallet refresh.
Global output indices are needed for removing a tx.

Both amount output indices and global output indices are now stored in
an array of 64-bit unsigned ints:

tx_outputs[<tx_hash>] -> [ <a1_oi, a1_gi, a2_oi, a2_gi, ...> ]

Previously it was:
tx_outputs[<tx_hash>] -> duplicate list of <a1_gi, a2_gi, a3_gi, ...>

The amount output list had to be walked for every amount in order to
find each amount's output index, by comparing the amount's global output
index with each one in the duplicate list until a match was found.
