Add updated bitcoin.conf from wiki + regtest #4306

a81cd968 introduced a malleability breaker for signatures
(using an even value for S). In e0e14e43 this was changed to
the lower of two potential values, rather than the even one.
Only the signing code was changed though, the (for now unused)
verification code wasn't adapted.

Conflict between low-s (6fd7ef2) and test updates in d3a33fc.

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.

None of the current integer parsing functions in util
check whether the result is valid and fits in the range
of the type. This is required for less sloppy error reporting.

Use the new function parseint32 in SplitHostPort instead of calling
strtol directly.

`-rpcallowip` currently has a wacky wildcard-based format. After this
commit it will accept the more standard format, for example:

- Ranges with netmask 127.0.0.0/255.255.255.0, ::/0
- Ranges with cidr 12.3.4.5/24, 12:34:56:78:9a:bc:de:00/112
- Loose IPs ::1, 127.0.0.1

Trying to use the old *?-based format will result in an error message at
launch.

No longer necessary after implementing netmask-based matching.
Also remove a longer-unused function `skipspaces`.

Use line buffering (instead of block buffering) so that messages arrive
immediately in systemd-journald, tail -f debug.log, and the like.

Size specifiers are no longer needed now that we use typesafe tinyformat
for string formatting, instead of the system's sprintf.

No functional changes.

This continues the work in #3735.

According to the [boost::asio documentation](http://www.boost.org/doc/libs/1_55_0/doc/html/boost_asio/reference/basic_socket_acceptor/async_accept/overload2.html),
the function signature of the handler must be:

    void handler(
      const boost::system::error_code& error // Result of operation.
    );

We were binding *all* the arguments, instead of all but the error,
resulting in nullary function that never got the error. Fix this
by adding an input argument substitution.

Make sure conn object always gets cleaned up by using a
`boost::shared_ptr`.

This makes valgrind happy - before this commit, one connection object
always leaked at shutdown, as well as can avoid other leaks, when
for example an exception happens.

Also add an explicit Close() to the !ClientAllowed path to make it similar
to the normal path (I'm not sure whether it is needed, but it
can't hurt).

That option hasn't existed for a long time.

Fixes #4156.

The problem is that the boost::asio::io_service destructor
waits for the acceptors to finish (on windows, and boost 1.55).

Fix this by keeping track of the acceptors and cancelling them before
stopping the event loops.

Pull updated translations from Transifex.

Add mn (Mongolian) language.

Do not update English translation for now as we want to keep
compatibility with 0.9.

Add -rpcbind command option to specify binding RPC service on one
or multiple specific interfaces.

Functionality if -rpcbind is not specified remains the same as before:

- If no -rpcallowip specified, bind on localhost
- If no -rpcbind specified, bind on any interface

Implements part of #3111.

First query in the current way (intelligently determining which network
has a non-localhost interface). If this does not succeed, try plain
lookup.

Needed for testing.

Fixes #1827 by always allowing IPv6 to be used.

Add a new test, `rpcbind_test.py`, that extensively tests the new
`-rpcbind` functionality.

i think should delete （#include "bitcoin-config.h"）。

Log the name of the error as well as the error code if a network problem
happens. This makes network troubleshooting more convenient.

Use thread-safe strerror_r and the WIN32 equivalent FormatMessage.

Make DateTimeStrFormat use boost::posix_time.

Also re-enable the util_DateTimeStrFormat tests, as they are no
longer platform specific.

Last-minute language update before release 0.9.2.

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

- as this is a shared Core/GUI setting, this makes it easier to keep them
  in sync (also no new includes are needed)

This fixes the display on Retina Macbooks. It also moves us away from depending
on the ancient XCode3 sdk.

Qt5 Removed the qt_mac_set_dock_menu function and left no replacement. It was
later re-added and deprecated for backwards-compatibility.

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

Weaken and clarify the wording a bit, it currently implies that we get
more pull requests than we can ever handle which discourages
contribution.

Pull updated translations from Transifex before 0.9.2

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.

Replaced label with text browser on About Bitcoin Core Screen

So that the links on the About screen can be clickable

Replaced html property with text property

I have now removed unnecessary html so this should make life easier for

- replaces checks in SendCoinsDialog::handlePaymentRequest() that belong
  to PaymentServer (normal URIs are special cased, as only an isValid
  check is done on BTC addresses)
- prevents the client to handle payment requests that do not match the
  clients network and shows an error instead (mainly a problem with
  drag&drop payment requests onto the client window)
- includes some small comment changes also

deleted the empty no throw test in rpc_wallet_tests line 65

fixed some comments

starting verify tests

finished verify message tests

changed some comments

- fix spaces, indentation and coding style glitches

I added a link to my guide about using docker containers + LXC (I am planning to maintain this at work
for future bitcoin versions), then I mentioned other virtualization options (KVM, LXC).
This commit includes a fix issue for documentation issue #4269 that consists in telling users to
checkout correct bitcoin version before using the gitian descriptors (otherwise all hell can break loose).
Also, I replaced URL for Debian 7.4 ISO with a correct one and added link to official Debian ISO sources.

Since they are not real opcodes, being reported as OP_UNKNOWN is less confusing for human-readable decoding.

- better code readability and it belongs to net
- this is a prerequisite for a pull to add -listen to the GUI

Don't repeat yourself etc.

A qt installation date snuck into the host utils (lrelease etc)
This doesn't affect the end product, so no dependency version bump.

It also doesn't explain why gavin's and mine build is different

This was forgotten in 25d4911.

A side-effect was introduced into an assertion in 7a0e84d. This commit
fixes that.

- to match info function between debug.log and RPCConsole

fe6bff2 and 65f78a1 broke it. Minor build changes.

As it says on the tin. There is no need to have this variable be
global, it's only used in AppInit2.

Build logic moves from individual Makefile.am's to include files, which
the main src/Makefile.am includes. This avoids having to manage a gigantic
single Makefile.

TODO: Move the rules from the old Makefile.include to where they actually
belong and nuke the old file.

Rules and targets no longer need to be shared between subdirectories, so
this is no longer needed.

- Some file generation was still noisy, silence it.
- AM_V_GEN is used rather than @ so that 'make V=1' works as intended
- Cut down on file copies and moves when using sed, use pipes instead
- Avoid the use of top_ and abs_ dirs where possible

Using them has the side effect of confusing the dependency-tracking logic.

Now that the build is non-recursive, adding to AM_CPPFLAGS means adding to
_all_ cppflags.

Logical groups of includes have been added instead, and are used individually
by various targets.

Use CFeeRate instead of an int64_t for quantities that are
fee-per-size.

Helps prevent unit-conversion mismatches between the wallet,
relaying, and mining code.

Choose ports at startup based on PID, so multiple regression tests
can run on the same system at the same time.

New RPC methods: return an estimate of the fee (or priority) a
transaction needs to be likely to confirm in a given number of
blocks.

Mike Hearn created the first version of this method for estimating fees.
It works as follows:

For transactions that took 1 to N (I picked N=25) blocks to confirm,
keep N buckets with at most 100 entries in each recording the
fees-per-kilobyte paid by those transactions.

(separate buckets are kept for transactions that confirmed because
they are high-priority)

The buckets are filled as blocks are found, and are saved/restored
in a new fee_estiamtes.dat file in the data directory.

A few variations on Mike's initial scheme:

To estimate the fee needed for a transaction to confirm in X buckets,
all of the samples in all of the buckets are used and a median of
all of the data is used to make the estimate. For example, imagine
25 buckets each containing the full 100 entries. Those 2,500 samples
are sorted, and the estimate of the fee needed to confirm in the very
next block is the 50'th-highest-fee-entry in that sorted list; the
estimate of the fee needed to confirm in the next two blocks is the
150'th-highest-fee-entry, etc.

That algorithm has the nice property that estimates of how much fee
you need to pay to get confirmed in block N will always be greater
than or equal to the estimate for block N+1. It would clearly be wrong
to say "pay 11 uBTC and you'll get confirmed in 3 blocks, but pay
12 uBTC and it will take LONGER".

A single block will not contribute more than 10 entries to any one
bucket, so a single miner and a large block cannot overwhelm
the estimates.

Upgrade for https://www.openssl.org/news/secadv_20140605.txt

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.
