d3b09f6 Do not allow blockfile pruning during reindex. (Alex Morcos)

The lock-time code currently uses CBlock::nTime as the cutoff point for time based locked transactions. This has the unfortunate outcome of creating a perverse incentive for miners to lie about the time of a block in order to collect more fees by including transactions that by wall clock determination have not yet matured. By using CBlockIndex::GetMedianTimePast from the prior block instead, the self-interested miner no longer gains from generating blocks with fraudulent timestamps. Users can compensate for this change by simply adding an hour (3600 seconds) to their time-based lock times.

If enforced, this would be a soft-fork change. This commit only adds the functionality on an unexecuted code path, without changing the behaviour of Bitcoin Core.

Transactions are not allowed in the memory pool or selected for inclusion in a block until their lock times exceed chainActive.Tip()->GetMedianTimePast(). However blocks including transactions which are only mature under the old rules are still accepted; this is *not* the soft-fork required to actually rely on the new constraint in production.

Until now there were quite a few leftovers, and only the coverage
related files in `src/` were cleaned, while the ones in the other dirs
remained. `qa/tmp/` is related to the BitcoinJ tests, and `cache/` is
related to RPC tests.

Because Python is (going to be) used to run the RPC tests, when
gathering coverage data with lcov, it is explicitly checked, whether
Python is really available.

When using lcov to gather code coverage data, the configuration option
`--enable-extended-rpc-tests` may be used to enable extended RPC tests.

The configuration option `--enable-comparison-tool-reorg-tests` may be
used to enable extended tests via BitcoinJ also for coverage testing.

The RPC tests (via `qa/pull-tester/rpc-tests.py`) are now executed,
when gathering code coverage data, for example with `make cov`.

Generating coverage data requires `lcov`, which can installed with:

    sudo apt-get install lcov

To also use the BitcoinJ tests, get the test tool:

    TOOL_URL=https://github.com/theuni/bitcoind-comparisontool/raw/master/pull-tests-8c6666f.jar
    TOOL_HASH=a865332b3827abcde684ab79f5f43c083b0b6a4c97ff5508c79f29fee24f11cd
    wget $TOOL_URL -O ./share/BitcoindComparisonTool.jar
    echo "$TOOL_HASH  ./share/BitcoindComparisonTool.jar" | shasum --algorithm 256 --check

The coverage data can be generated with:

    ./autogen.sh
    ./configure --enable-lcov --with-comparison-tool=./share/BitcoindComparisonTool.jar
    make
    make cov

Optionally the options `--enable-extended-rpc-tests` and
`--enable-comparison-tool-reorg-tests` may be used to enable more time
consuming tests.

It then runs the tests and generates two HTML reports:

 - test_bitcoin.coverage/index.html
 - total.coverage/index.html

- ensure all missing catch cases are constant where possible

- ensure header namespaces and end comments are correct
- add missing header end comments
- ensure minimal formatting (add newlines etc.)

Update the unittest that is meant to catch a transaction that is invalid
because it has a null input.  The old test failed not because of that
but because it was considered a coinbase with too large script.  This is
already checked with a different test, though.

The new test is *not* a coinbase since it has two inputs, but one of
them is null.  This really checks the corresponding code path in
CheckTransaction.

create_coinbase() was being called with the wrong arguments

This reverts commit dea8d21fc63e9f442299c97010e4740558f4f037.

This reverts commit 9d55050773d57c0e12005e524f2e54d9e622c6e2.

As noted by Luke-Jr, under some conditions this will accept transactions which are invalid by the network
 rules.  This happens when the current block time is head of the median time past and a transaction's
 locktime is in the middle.

This could be addressed by changing the rule to MAX(this_block_time, MTP+offset) but this solution and
 the particular offset used deserve some consideration.

This file is dynamically generated by configure based on the platform,
it doesn't belong in the distribution archive.

Fixes #6929.

8537ecd Revert "Enable policy enforcing GetMedianTimePast as the end point of lock-time constraints" (Gregory Maxwell)

When processing a new transaction, in addition to spending the Coins of its txin's it creates a new Coins for its outputs.  The existing ModifyCoins function will first make sure this Coins does not already exist.  It can not exist due to BIP 30, but because of that the lookup can't be cached and always has to go to the database.  Since we are creating the coins to match the new tx anyway, there is no point in checking if they exist first anyway.  However this should not be used for coinbase tx's in order to preserve the historical behavior of overwriting the two existing duplicate tx pairs.

Previously, the undo weren't being flushed during a reindex because
fKnown was set to true in FindBlockPos. That is the correct behaviour
for block files as they aren't being touched, but undo files are
touched.

This changes the behaviour to always flush when switching to a new file
(even for block files, though that isn't really necessary).

7ca73dc Improving labels for Sent / Received "Bytes" (Jonathan Cross)

Starting with Tor version 0.2.7.1 it is possible, through Tor's control socket
API, to create and destroy 'ephemeral' hidden services programmatically.
https://stem.torproject.org/api/control.html#stem.control.Controller.create_ephemeral_hidden_service

This means that if Tor is running (and proper authorization is available),
bitcoin automatically creates a hidden service to listen on, without user
manual configuration. This will positively affect the number of available
.onion nodes.

- When the node is started, connect to Tor through control socket
- Send `ADD_ONION` command
- First time:
    - Make it create a hidden service key
    - Save the key in the data directory for later usage
- Make it redirect port 8333 to the local port 8333 (or whatever port we're listening on).
- Keep control socket connection open for as long node is running. The hidden service will
  (by default) automatically go away when the connection is closed.

01afa80 doc: Remove mention of pulltester from README.md (Wladimir J. van der Laan)

This continues/fixes #6719.

`event_base_loopbreak` was not doing what I expected it to, at least in
libevent 2.0.21.
What I expected was that it sets a timeout, given that no other pending
events it would exit in N seconds. However, what it does was delay the
event loop exit with 10 seconds, even if nothing is pending.

Solve it in a different way: give the event loop thread time to exit
out of itself, and if it doesn't, send loopbreak.

This speeds up the RPC tests a lot, each exit incurred a 10 second
overhead, with this change there should be no shutdown overhead in the
common case and up to two seconds if the event loop is blocking.

As a bonus this breaks dependency on boost::thread_group, as the HTTP
server minds its own offspring.
