d76412b068 Add script manipulation tools for use in mininode testing framework
script.py is modified from the code in python-bitcoinlib, and provides tools
for manipulating and creating CScript objects.

bignum.py is a dependency for script.py

script_test.py is an example test that uses the script tools for running a test
that compares the behavior of two nodes, in a comptool- style test, for each of
the test cases in the bitcoin unit test script files, script_valid.json and
script_invalid.json.  (This test is very slow to run, but is a proof of concept
for how we can write tests to compare consensus-critical behavior between
different versions of bitcoind.)

bipdersig-p2p.py is another example test in the comptool framework, which tests
deployment of BIP DERSIG for a single node.  It uses the script.py tools for
manipulating signatures to be non-DER compliant.

b93974c3f3 Add comparison tool test runner, built on mininode
comptool.py creates a tool for running a test suite on top of the mininode p2p
framework.  It supports two types of tests: those for which we expect certain
behavior (acceptance or rejection of a block or transaction) and those for
which we are just comparing that the behavior of 2 or more nodes is the same.

blockstore.py defines BlockStore and TxStore, which provide db-backed maps
between block/tx hashes and the corresponding block or tx.

blocktools.py defines utility functions for creating and manipulating blocks
and transactions.

invalidblockrequest.py is an example test in the comptool framework, which
tests the behavior of a single node when sent two different types of invalid
blocks (a block with a duplicated transaction and a block with a bad coinbase
value).

6c1d1ba6fc Python p2p testing framework
mininode.py provides a framework for connecting to a bitcoin node over the p2p
network. NodeConn is the main object that manages connectivity to a node and
provides callbacks; the interface for those callbacks is defined by NodeConnCB.
Defined also are all data structures from bitcoin core that pass on the network
(CBlock, CTransaction, etc), along with de-/serialization functions.

maxblocksinflight.py is an example test using this framework that tests whether
a node is limiting the maximum number of in-flight block requests.

This also adds support to util.py for specifying the binary to use when
starting nodes (for tests that compare the behavior of different bitcoind
versions), and adds maxblocksinflight.py to the pull tester.

QA: add --noshutdown option to prevent stopping nodes
With `--noshutdown`, the nodes are not stopped explicitly. `--noshutdown` implies `--nocleanup`, to prevent removing datadirs, which are still in use.

f9ec3f0fad Add block pruning functionality
This adds a -prune=N option to bitcoind, which if set to N>0 will enable block
file pruning. When pruning is enabled, block and undo files will be deleted to
try to keep total space used by those files to below the prune target (N, in
MB) specified by the user, subject to some constraints:

- The last 288 blocks on the main chain are always kept (MIN_BLOCKS_TO_KEEP),
- N must be at least 550MB (chosen as a value for the target that could
  reasonably be met, with some assumptions about block sizes, orphan rates,
  etc; see comment in main.h),
- No blocks are pruned until chainActive is at least 100,000 blocks long (on
  mainnet; defined separately for mainnet, testnet, and regtest in chainparams
  as nPruneAfterHeight).

This unsets NODE_NETWORK if pruning is enabled.

Also included is an RPC test for pruning (pruning.py).

Thanks to @rdponticelli for earlier work on this feature; this is based in
part off that work.

QA: stop nodes after RPC tests, even with --nocleanup
`--nocleanup` should provide a way to preserve test data, but should not have an impact on whether nodes are to be stopped after the test execution.

In particular, when currently running RPC tests with `--nocleanup`, then it may result in several active `bitcoind` processes, which are not terminated properly.

0421c18f3a Fix CheckBlockIndex for reindex.
Some tests in CheckBlockIndex require chainActive.Tip(), but when reindexing, chainActive has not been set on the first call to CheckBlockIndex.

reindex.py starts a node, mines 3 blocks, stops, and reindexes with CheckBlockIndex enabled.

Regression test for ResendWalletTransactions
Adds a regression test for the wallet's ResendWalletTransactions function, which uses a new, hidden RPC command "resendwallettransactions."

I refactored main's Broadcast signal so it is passed the best-block time, which let me remove a global variable shared between main.cpp and the wallet (nTimeBestReceived).

I also manually tested the "rebroadcast unconfirmed every half hour or so" functionality by:

1. Running bitcoind -connect=0.0.0.0:8333
2. Creating a couple of send-to-self transactions
3. Connect to a peer using -addnode
4. Waited a while, monitoring debug.log, until I see:
```2015-03-23 18:48:10 ResendWalletTransactions: rebroadcast 2 unconfirmed transactions```

One last change: don't bother putting ResendWalletTransactions messages in debug.log unless unconfirmed transactions were actually rebroadcast.

005b5af6e2 rpc-tests: don't spew non-errors to stdout
There's a brief race here, the process might've already exited and cleaned up
after itself. If that's the case, reading from the pidfile will harmlessly
fail. Keep those quiet.

Trigger -alertnotify if network is upgrading without you
This adds a -regetest-only undocumented (for regression testing only)
command-line option -blockversion=N to set block.nVersion.

Adds to the "has the rest of the network upgraded to a
block.nVersion we don't understand" code so it calls
-alertnotify when 51 of the last 100 blocks are up-version.
But it only alerts once, not with every subsequent new, upversion
block.

And adds a forknotify.py regression test to make sure it works.

Tested using forknotify.py:

Before adding CAlert::Notify, get:
Assertion failed: -alertnotify did not warn of up-version blocks

Before adding code to only alert once:
Assertion failed: -alertnotify excessive warning of up-version blocks

After final code in this pull:
Tests successful

5ad450a65a travis: If the comparison-tool fails, dump the tail of the debug log
The entire debug log would be huge, and could cause issues for automated tools
like travis. Printing 200 lines is an initial guess at a reasonable number,
more may be required.

b33bd7a3be Implement "getchaintips" RPC command to monitor blockchain forks.
Port over https://github.com/chronokings/huntercoin/pull/19 from
Huntercoin:  This implements a new RPC command "getchaintips" that can be
used to find all currently active chain heads.  This is similar to the
-printblocktree startup option, but it can be used without restarting
just via the RPC interface on a running daemon.
