Previously if bitcoind is linked with an OpenSSL which is compiled
without EC support, this is seen as an assertion failure "pKey !=
NULL" at key.cpp:134, which occurs after several seconds. It is an
esoteric piece of knowledge to interpret this as "oops, I linked
with the wrong OpenSSL", and because of the delay it may not even
be noticed.

The new output is

: OpenSSL appears to lack support for elliptic curve cryptography. For
more information, visit
https://en.bitcoin.it/wiki/OpenSSL_and_EC_Libraries
: Initialization sanity check failed. Bitcoin Core is shutting down.

which occurs immediately after attempted startup.

This also blocks in an InitSanityCheck() function which currently only
checks for EC support but should eventually do more. See #4081.

```
$ ./bitcoin-qt 'bitcoin:?r=http://www.example.com/'
.. fixed the original problem - this launches mainnet.

Generally useless information. Only updates on connect time, not after
that. Peers can easily lie and the median filter is not effective in
preventing that.

In the past it was used for progress display in the GUI but
`CheckPoints::guessVerificationProgress` provides a better way that is now used.
It was too easy to mislead it. Peers do lie about it in practice, see issue #4065.

From the RPC, `getpeerinfo` gives the peer raw values, which are more
useful.

Cancelling the RPC acceptors can sometimes result in an error about
a bad file descriptor.

As this is the shutdown sequence we need to continue nevertheless,
ignore these errors, log a warning and proceed.

Fixes #4352.

The "Monospace" hint was added in Qt 4.8, and it works as intended as opposed
to "TypeWriter" which fails to load a font.

Just in case - there is no vulnerability that affects ecdsa signing or
verification.

The MITM attack vulnerability (CVE-2014-0224) may have some effect on
our usage of SSL/TLS.

As long as payment requests are signed (which is the common case), usage
of the payment protocol should also not be affected.

The TLS usage in RPC may be at risk for MITM attacks. If you have
`-rpcssl` enabled, be sure to update OpenSSL as soon as possible.

NodeSyncScore() should find the node which we recv data most recently, so put a negative sign to pnode->nLastRecv is indeed wrong.

Also change the return value type to int64_t.

Qt5 Removed the qt_mac_set_dock_menu function and left no replacement. It was

Qt5.2 adds the non-deprecated QMenu::setAsDockMenu(). Use that when possible.
