The "A fatal internal error occurred, see debug.log for details" is
redundant because init.cpp will already show an InitError with a better
error message as well as the hint to check the debug.log

0000ea32656833efa3d2ffd9bab66c88c83334f0 test: Add test for GetRandMillis and GetRandMicros (MarcoFalke)
fa0e5b89cf742df56c6c8f49fe9b3c54d2970a66 Add templated GetRandomDuration<> (MarcoFalke)
Pull request description:
A naive implementation of this template is dangerous, because the call site might accidentally omit the template parameter:
```cpp
template <typename D>
D GetRandDur(const D& duration_max)
{
return D{GetRand(duration_max.count())};
}
BOOST_AUTO_TEST_CASE(util_time_GetRandTime)
{
std::chrono::seconds rand_hour = GetRandDur(std::chrono::hours{1});
// Want seconds to be in range [0..1hour), but always get zero :((((
BOOST_CHECK_EQUAL(rand_hour.count(), 0);
}
```
Luckily `std::common_type` is already specialised in the standard lib for `std::chrono::duration` (https://en.cppreference.com/w/cpp/chrono/duration/common_type). And its effect seem to be that the call site must always specify the template argument explicitly.
So instead of implementing the function for each duration type by hand, replace it with a templated version that is safe to use.

746736639e6d05acdb85c866d4c605c947d4c500 [net processing] Only send a getheaders for one block in an INV (John Newbery)
Pull request description:
Headers-first is the primary method of announcement on the network. If a node fell back sending blocks by inv, it's probably for a re-org. The final block hash provided should be the highest, so send a getheaders and then fetch the blocks we need to catch up.
Sending many GETHEADERS messages to the peer would cause them to send a large number of potentially large HEADERS messages with redundant data, which is a waste of bandwidth.

Pull request description:
When a validationinterface has itself unregistered in one thread, but is about to get executed in another thread [1], there is a race:
* The validationinterface destructing itself
* The validationinterface getting dereferenced for execution
[1] https://github.com/bitcoin/bitcoin/blob/64139803f1225dab26197a20314109d37fa87d5f/src/validationinterface.cpp#L82-L83
This happens in the miner. More generally it happens everywhere where at least one thread is generating notifications and another one is unregistering a validationinterface.
This issue has been fixed in commit ab31b9d6fe7b39713682e3f52d11238dbe042c16, but the fix has not been applied to the miner.

This is achieved by switching to a shared_ptr.
Also, switch the validationinterfaces in the tests to use shared_ptrs
for the same reason.

df6bde031b24112abf3a94337a2c096698acde6e test: remove glibc fdelt sanity check (fanquake)
8bf1540cc235fb8fb5330a7ae8ab638247ceb177 build: remove fdelt_chk backwards compatibility code (fanquake)
Pull request description:
https://github.com/bitcoin/bitcoin/commit/ae30d40e50e9d63d875d29d54d22147b09fc420c
The return type of [`fdelt_chk`](https://sourceware.org/git/?p=glibc.git;a=blob;f=debug/fdelt_chk.c;h=f62ce7349707cb68f55831c1c591fd7387a90258;hb=HEAD) changed from `unsigned long int` to `long int` in glibc 2.16. See [this commit](https://sourceware.org/git/?p=glibc.git;a=commit;h=ceb9e56b3d1f8c1922e0526c2e841373843460e2). Now that we require [glibc >=2.17](https://github.com/bitcoin/bitcoin/pull/17538) we can remove our back-compat code.
https://github.com/bitcoin/bitcoin/commit/ab7bce584ae02bf25e2e91aa54f9b0249427127d
While looking at the above changes, I noticed that our glibc fdelt sanity check doesn't seem to be checking anything. `fdelt_warn()` also isn't something we'd want to actually "trigger" at runtime, as doing so would cause `bitcoind` to abort.
The comments:
> // trigger: Call FD_SET to trigger __fdelt_chk. FORTIFY_SOURCE must be defined
> // as >0 and optimizations must be set to at least -O2.
suggest calling FD_SET to check the invocation of `fdelt_chk` (this is [aliased with fdelt_warn in glibc](https://sourceware.org/git/?p=glibc.git;a=blob;f=debug/fdelt_chk.c;h=f62ce7349707cb68f55831c1c591fd7387a90258;hb=HEAD)). However just calling `FD_SET()` will not necessarily cause the compiler to insert a call to `fd_warn()`.
Whether or not GCC (recent Clang should work, but may use different heuristics) inserts a call to `fdelt_warn()` depends on if the compiler can determine if the value passed in is a compile time constant (using [`__builtin_constant_p`](https://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html)) and whether the value is < 0 or >= `FD_SETSIZE`. The glibc implementation is [here](https://sourceware.org/git/?p=glibc.git;a=blob;f=misc/bits/select2.h;h=7e17430ed94dd1679af10afa3d74795f9c97c0e8;hb=HEAD). This means our check should never cause a call to be inserted.
Compiling master without `--glibc-back-compat` (if you do pass `--glibc-back-compat` the outcome is still the same; however the abort will only happen with >=`FD_SETSIZE` as that is what our [fdelt_warn()](https://github.com/bitcoin/bitcoin/blob/master/src/compat/glibc_compat.cpp#L24) checks for), there are no calls to `fdelt_warn()` inserted by the compiler:
```bash

```
If you modify the sanity test to pass `-1` or `FD_SETSIZE` to `FD_SET`, you'll see calls to `fdelt_warn` inserted, and the runtime behaviour is an abort as expected.

I think the test should should be removed and replaced (if possible) with additional checks in security-check.py. I was thinking about adding a version of [this script](https://github.com/fanquake/core-review/blob/master/fortify.py) as part of the output, but that needs more thought. I'll address this in a follow up.

a8b5f1b133d4f23975a3fbfb7a415b17261466ee gui: Fix manual coin control with multiple wallets loaded (João Barbosa)
Pull request description:
This PR ensures each loaded wallet has a dedicated coin control in the send view which is manipulated by the coin control dialog.
This is an alternative to #17457. Two main differences are:
- scope reduced - no unnecessary changes unrelated to the fix;
- approach taken - coin control instance now belongs to the send view.
All problems raised in #17457 reviews no longer apply due to the approach taken - https://github.com/bitcoin/bitcoin/pull/17457#pullrequestreview-319297589 and https://github.com/bitcoin/bitcoin/pull/17457#issuecomment-555920829)
No change in behavior if only one wallet is loaded.
Closes #15725.

Code review ACK a8b5f1b133d4f23975a3fbfb7a415b17261466ee. Code changes are very straightforward, just replacing global CCoinControl object with SendCoinsDialog member. Not sure if this means coin control settings are reset between payments. It would be good to note in the PR description or release notes if single wallet behavior is affected

Headers-first is the primary method of announcement on the network. If a
node fell back sending blocks by inv, it's probably for a re-org. The
final block hash provided should be the highest, so send a getheaders
and then fetch the blocks we need to catch up.

`static constexpr CMessageHeader::HEADER_SIZE` is already used in this file, `src/net.cpp`, in 2 instances. This commit replaces the remaining 2 integer values in the file with it and adds the explicit include header.

Pull request description:
Currently we'll stall peers that send us an unknown INV type in a GETDATA message. Be a bit more friendly and just drop the invalid request.
Ditto for blocks-relay-only peers that send us a GETDATA for a transaction.
There's a test for the first part. The second is difficult to test in the functional test framework since we aren't able to make blocks-relay-only connections.

1551cea2d52cac403ff506a7cc955d8de8fd6f3e refactor: Use override for non-final overriders (Hennadii Stepanov)
Pull request description:
Two commits are split out from #16710 to make reviewing [easier](https://github.com/bitcoin/bitcoin/pull/16710#issuecomment-625760894).
From [C++ FAQ](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines.html#c128-virtual-functions-should-specify-exactly-one-of-virtual-override-or-final):
> C.128: Virtual functions should specify exactly one of virtual, override, or final
> **Reason** Readability. Detection of mistakes. Writing explicit `virtual`, `override`, or `final` is self-documenting and enables the compiler to catch mismatch of types and/or names between base and derived classes. However, writing more than one of these three is both redundant and a potential source of errors.

pwallet is never null everywhere where it is dereferenced, so simply
replace it with a reference, which can not be null by definition.

Optional::emplace() was only added in boost 1.56, see

replace it with assignment of T{}

Pull request description:
Disallowing sign-comparison mismatches can help to prevent the introduction of overflow and interpretation bugs.
In this case, ~all~ most existing violations are in the tests, and most simply required annotating the literal as unsigned for comparison.
This was previously prevented by violations in leveldb which were fixed upstream and merged in #17398. You can test that by building this branch against: 22d11187ee3c7abfe9d43c9eb68f102498cc2b9a vs 75fb37ce68289eb7e00e2ccdd2ef7f9271332545

If -peerblockfilters is configured, handle requests for cfcheckpt.
|
|
When a node is configured with --blockfilterindex=basic and
-peerblockfilters it can serve compact block filters to its peers.
This commit adds the configuration option handling. Future commits
add compact block serving and service bits signaling.

Pull request description:
This is an alternative to #15340 (it works with the `Chain` interface; see: https://github.com/bitcoin/bitcoin/pull/15340#issuecomment-502674004).
Refs:
- #16218 (partial fix)
- https://github.com/bitcoin/bitcoin/pull/15894#issuecomment-487947077
This PR:
- makes GUI error messages bilingual: user's native language + untranslated (i.e. English)
- insures that only untranslated messages are written to the debug log file and to `stderr` (that is not the case on master).
If a translated string is unavailable only an English string appears to a user.
Here are some **examples** (updated):
* `qt5ct: using qt5ct plugin` message is my local environment specific; please ignore it.
