1630219d90 openssl: abstract out OPENSSL_cleanse
This makes it easier for us to replace it if desired, since it's now only in
one spot. Also, it avoids the openssl include from allocators.h, which
essentially forced openssl to be included from every compilation unit.

78c6bedb9c Add test for DER-encoding edge case
The fix to NegateSignatureS caused a test which had been failing
in IsValidSignatureEncoding to then fail in IsLowDERSignature.
Add new test so the original check remains exercised.

6f50dbd2fd Fix NegateSignatureS to not duplicate last byte of S
NegateSignatureS is called with a signature without a hashtype, so
do not save the last byte and append it after S negation.

Updates the two tests which were affected by this bug.

28d4cff0ed Sanitize command strings before logging them.
Normally bitcoin core does not display any network originated strings without
 sanitizing or hex encoding.  This wasn't done for strcommand in many places.

This could be used to play havoc with a terminal displaying the logs,
 especially with printtoconsole in use.

Thanks to Evil-Knievel for reporting this issue.

dca799e1db Ignore getaddr messages on Outbound connections.
The only time when a client sends a "getaddr" message is when he
esatblishes an Outbound connection (see ProcessMessage() in
src/main.cpp).  Another bitcoin client is expected to receive a
"getaddr" message only on Inbound connection. Ignoring "gettaddr"
requests on Outbound connections can resolve potential privacy issues
(and as was said such request normally do not happen anyway).

25cf6f3d41 minor rework of SendMoney in rpcwallet

a6516686dc [Qt] prevent amount overflow problem with payment requests
Bitcoin amounts are stored as uint64 in the protobuf messages (see
paymentrequest.proto), but CAmount is defined as int64_t. Because
of that we need to verify that single and accumulated amounts are
in a valid range and no variable overflow has happened.

- fixes #5624 (#5622)

Thanks @SergioDemianLerner for reporting that issue and also supplying us
with a possible solution.

- add static verifyAmount() function to PaymentServer and move the logging
  on error into the function
- also add a unit test to paymentservertests.cpp

3447cf87e2 c++11: MOVEONLY: break circular dependency in wallet
c++11 (libc++'s stdlib implementation anyway) doesn't allow for map types to be
forward-declared. for example:

class foo;
std::map<int, foo> bar; // error, foo has not been defined.
class foo{};

Since CWallet and CWalletTx are inter-dependent, but only std::map<*,CWalletTx>
is used, forward-declare CWallet instead and define CWalletTx first.

Despite the mangled git diff, this change only amounts to moving ~320 lines in
a single chunk.

"A fee higher than %1 is considered an absurdly high fee."

52954e6efd qt: fix broken unicode chars on osx 10.10
The default font changed again.

The real fix is to compile qt against a >= 10.8 sdk, but this is simple enough
to backport to 0.10 to avoid having to do that there.

Note: NSAppKitVersionNumber is a double and there's no official value for
NSAppKitVersionNumber10_10. Since == isn't reliable for doubles, use Apple's
guidelines for testing versions here:
https://developer.apple.com/library/mac/releasenotes/AppKit/RN-AppKit/

Chinese and Japanese fonts have been hard-coded as well, otherwise they fail to
show up at all.

7d2cb48511 Restore RPC HTTP keepalives to default.
This avoids a regression for issues like #334 where high speed
 repeated connections eventually run the HTTP client out of
 sockets because all of theirs end up in time_wait.

Maybe the trade-off here is suboptimal, but if both choices will
 fail then we prefer fewer changes until the root cause is solved.

6715efb9ca [Qt] Payment request expiration bug fix (re-done)
- this is based on #4122 (which can be closed)

Currently a payment request is only checked for expiration upon receipt.
It should be checked again immediately before sending coins to prevent
the user from paying to an expired invoice which would then require a
customer service interaction.

- add static verifyExpired() function to PaymentServer to be able to use
  the same validation code in GUI and unit-testing code
- extend unit tests to use that function and also add an unit test which
  overflows, because payment requests allow expires as uint64, whereas we
  use int64_t for verification of expired payment requests

16a5c18cea Add a -rpckeepalive and disable RPC use of HTTP persistent connections.
It turns out that some miners have been staying with old versions of
 Bitcoin Core because their software  behaves poorly with persistent
 connections and the Bitcoin Core thread and connection limits.

What happens is that underlying  HTTP libraries leave connections open
 invisibly to their users and then the user runs into the default four
 thread limit.  This looks like Bitcoin Core is unresponsive to RPC.

There are many things that should be improved in Bitcoin Core's behavior
 here, e.g. supporting more concurrent connections, not tying up threads
 for idle connections, disconnecting kept-alive  connections when limits
 are reached, etc. All are fairly big, risky changes.

Disabling keep-alive is a simple workaround. It's often not easy to turn
 off the keep-alive support in the client where it may be buried in some
 platform library.

If you are one of the few who really needs persistent connections you
 probably know that you want them and can find a switch; while if you
 don't and the misbehavior is hitting you it is hard to discover the
 source of your problems is keepalive related.  Given that it is best
 to default to off until they're handled better.
