a2eb6f5405 [rpc] Add getnodeaddresses RPC command (chris-belcher)
Pull request description:
Implements issue https://github.com/bitcoin/bitcoin/issues/9463
New getnodeaddresses call gives access via RPC to the peers known by the node. It may be useful for bitcoin wallets to broadcast their transactions over tor for improved privacy without using the centralized DNS seeds. getnodeaddresses is very similar to the getaddr p2p method.
Please advise me on the best approach for writing an automated test. By my reading the getaddr p2p method also isn't really tested.

This patch improves the built-in RNG using hash strengthening.
At startup, and once every minute, 32 bytes of entropy are produced from the RNG, repeatedly hashed using SHA512 for 10ms, and then fed back into the RNG, together with high-precision timestamps obtained every 1000 iterations.

8734c856f85cb506fa97596383dd7e7b9edd7e03 Replace the LogPrint function with a macro (Jeffrey Czyz)
Pull request description:
Calling `LogPrint` with a category that is not enabled results in
evaluating the remaining function arguments, which may be arbitrarily
complex (and possibly expensive) expressions. Defining `LogPrint` as a
macro prevents this unnecessary expression evaluation.
This is a partial revert of #14209. The decision to revert is discussed
in #16688, which adds verbose logging for validation event notification.

cc3b5289ef648dca30469ee4afa615a1ed5b4e04 gui: remove OpenSSL PRNG seeding (Windows, Qt only) (fanquake)
Pull request description:
This removes the code introduced in [#4399](https://github.com/bitcoin/bitcoin/pull/4399) that attempts to add additional entroy to the OpenSSL PRNG using `RAND_event()`. This is specific to bitcoin-qt running on Windows.
```
RAND_event() collects the entropy from Windows events such as mouse movements and other user interaction.
It should be called with the iMsg, wParam and lParam arguments of all messages sent to the window procedure.
It will estimate the entropy contained in the event message (if any), and add it to the PRNG.
The program can then process the messages as usual.
```
Besides BIP70, this is the last place we are directly using OpenSSL in the GUI code. All other OpenSSL usage is in [random.cpp](https://github.com/bitcoin/bitcoin/blob/master/src/random.cpp).
Note that we are still also still doing other Windows specific gathering using [RandAddSeedPerfmon](https://github.com/bitcoin/bitcoin/blob/master/src/random.cpp#L268) and [RAND_screen()](https://github.com/bitcoin/bitcoin/blob/master/src/random.cpp#L600) on top of the other generation we do.
Also note that if RAND_event returns `0` here (PRNG has **NOT** been seeded with enough data), we're just logging a single message and continuing, which also seems less than ideal.

3284e6c09a84e9557ec72723ad636053d3ef7122 scripts: search for next position of magic bytes rather than fail (Tim Akinbo)
Pull request description:
When using the `linearize-data.py` contrib script to export block data, there are edge cases where the script fails with an `Invalid magic: 00000000` error. This error occurs due to the presence of padding bytes that occasionally appears between consecutive blocks in the block data file.
There's an ongoing conversation about this in #14986. sipa also admitted that it is a bug in #5028. Fortunately, this is not an issue in bitcoin core as it handles this type of situation gracefully and so no fix in bitcoin core is required.
This PR is an improvement on how the script handles these "invalid magic bytes". Rather than failing, this patch allows the script to search for the next occurrence of the magic bytes and then starts reading the block from there.

Pull request description:
Switch one of the Travis jobs to an unsigned char environment (`-funsigned-char`).
This will help us catch errors due to code written under the assumption that `char` has the same value range as `signed char`.
The signedness of `char` is implementation-defined.
Example:
```
$ uname -a
Linux […] x86_64 x86_64 x86_64 GNU/Linux
$ cat foo.cpp
#include <iostream>
int main() {
char c;
std::cin >> c;
int i = (unsigned char)c;
std::cout << i << "\n";
}
$ clang++ -o foo foo.cpp
$ echo -e "\xff" | ./foo
255
$ clang++ -fsigned-char -o foo foo.cpp
$ echo -e "\xff" | ./foo
255
$ clang++ -funsigned-char -o foo foo.cpp
$ echo -e "\xff" | ./foo
255
$ cat bar.cpp
#include <iostream>
int main() {
char c;
std::cin >> c;
int i = c;
std::cout << i << "\n";
}
$ clang++ -o bar bar.cpp
$ echo -e "\xff" | ./bar
-1
$ clang++ -fsigned-char -o bar bar.cpp
$ echo -e "\xff" | ./bar
-1
$ clang++ -funsigned-char -o bar bar.cpp
$ echo -e "\xff" | ./bar
255
```
`gcc` chars:
* signed: alpha, hppa, ia64, m68k, mips, sh, sparc, x86
* unsigned: arm, powerpc, s390
About `-funsigned-char`:
> Let the type "char" be unsigned, like "unsigned char".
>
> Each kind of machine has a default for what "char" should be. It is either like "unsigned char" by default or like "signed char" by default.
>
> Ideally, a portable program should always use "signed char" or "unsigned char" when it depends on the signedness of an object. But many programs have been written to use plain "char" and expect it to be signed, or expect it to be unsigned, depending on the machines they were written for.
>
> This option, and its inverse, let you make such a program work with the opposite default. The type "char" is always a distinct type from each of "signed char" or "unsigned char", even though its behavior is always just like one of those two.
