Previously the minRelayTxFee was only enforced on user specified values.
It was possible for smartfee to produce a fee below minRelayTxFee which
would just result in the transaction getting stuck because it can't be
relayed.
This also introduces a maxtxfee option which sets an absolute maximum
for any fee created by the wallet, with an intention of increasing
user confidence that the automatic fees won't burn them. This was
frequently a concern even before smartfees.
If the configured fee policy won't even allow the wallet to meet the relay
fee the transaction creation may be aborted.

50db7d9 [Qt] change some strings to reflect name change to Bitcoin Core (Philip Kaufmann)
2747f7c [Qt] fix missing plural form for a string in sendcoinsdialog (Philip Kaufmann)
'Sane' was already defined by this code as:
fee.GetFeePerK() > minRelayFee.GetFeePerK() * 10000
But sanity was only enforced for data loaded from disk.
Note that this is a pretty expansive definition of 'sane': A 10 BTC
fee is still passes the test if its on a 100kb transaction.
This prevents a single insane fee on the network from making us reject
our stored fee data at start. We still may reject valid saved fee
state if minRelayFee is changed between executions.
This also reduces the risk and limits the damage from a cascading
failure where one party pays a bunch of insane fees which cases
others to pay insane fees.
This is a check that is mentioned in BIP 37, but never implemented in the
reference code. As Bitcoin Core so far never decodes partial merkle trees,
this is not a problem. But perhaps others use the code as a reference.

This still leaves transactions in mempool that are potentially
invalid if the maturity period has been reorged out of, but at
least they're not missing inputs entirely.
- current code only does this for payment request files, which are
used on Mac
- also rename readPaymentRequest to readPaymentRequestFromFile, so it's
obvious that function only handles payment request files and not URIs
- small logging changes in readPaymentRequestFromFile
TLS is subject to downgrade attacks when SSLv3 is available, and
SSLv3 has vulnerabilities.
The popular solution is to disable SSLv3. On the web this breaks
some tiny number of very old clients. While Bitcoin RPC shouldn't
be exposed to the open Internet, it also shouldn't be exposed to
really old SSL implementations, so it shouldn't be a major issue
for us to disable SSLv3.
There is more information on the downgrade attacks and disabling
SSLv3 at https://disablessl3.com/ .

OP_CODESEPARATOR is an actual executed instruction, not a declarative
thing, so if it's wrapped in an OP_IF it can be turned off.
Using this to implement Rivest's Paywords is left as an exercise for the
reader.
Although script_valid.json and script_invalid.json are loaded correctly by the
JSON interpreter used by bitcoin core, these same files are often used by other
libraries and do not necessarily load correctly due to the fact that newlines
contained inside strings are not valid and must instead use the escape
character \n. The files tx_valid.json and tx_invalid.json handle this
correctly, so I've changed the formatting in script_valid.json and
script_invalid.json to mirror those files.
362001c Move CHECKMULTISIG order tests out of automatically generated block (Pieter Wuille)
f67a9ce Use deterministically generated script tests (Pieter Wuille)
This avoids connecting to them again too soon in ThreadOpenConnections.
Make an exception for connection failures to the proxy as these
shouldn't affect the status of specific nodes.
Now that signing is deterministic, we can require exact correspondence between the
automatically generated tests and the ones read from JSON. Do this, and update
the tests to those deterministic versions. Note that some flag changes weren't
correctly applied before.
1. Remove the default format (binary) because `rest/block/<hash>/Hex` would end up delivering binary data.

Based on an earlier patch by Peter Todd, though the rules here are different
(P2SH scripts should not have a CLEANSTACK check before the P2SH evaluation).
There are 3 pieces of data that are maintained on disk. The actual block
and undo data, the block index (which can refer to positions on disk),
and the chainstate (which refers to the best block hash).
Earlier, there was no guarantee that blocks were written to disk before
block index entries referring to them were written. This commit introduces
dirty flags for block index data, and delays writing entries until the actual
block data is flushed.
With this stricter ordering in writes, it is now safe to not always flush
after every block, so there is no need for the IsInitialBlockDownload()
check there - instead we just write whenever enough time has passed or
the cache size grows too large. Also updating the wallet's best known block
is delayed until this is done, otherwise the wallet may end up referring to an
unknown block.
In addition, only do a write inside the block processing loop if necessary
(because of cache size exceeded). Otherwise, move the writing to a point
after processing is done, after relaying.
