It includes the following policy changes:
* All GetRand* functions seed the stack pointer and rdrand result
(in addition to the performance counter)
* The periodic entropy added by the idle scheduler now seeds stack pointer,
rdrand and perfmon data (once every 10 minutes) in addition to
just a sleep timing.
* The entropy added when calling GetStrongRandBytes no longer includes
the once-per-10-minutes perfmon data on windows (it is moved to the
idle scheduler instead, where latency matters less).
Other changes:
* OpenSSL is no longer seeded directly anywhere. Instead, any generated
randomness through our own RNG is fed back to OpenSSL (after an
additional hashing step to prevent leaking our RNG state).
* Seeding that was previously done directly in RandAddSeedSleep is now
moved to SeedSleep(), which is indirectly invoked through ProcRand
from RandAddSeedSleep.
* Seeding that was previously done directly in GetStrongRandBytes()
is now moved to SeedSlow(), which is indirectly invoked through
ProcRand from GetStrongRandBytes().
This guarantees that OpenSSL is initialized properly whenever randomness
is used, even when that randomness is invoked from global constructors.
Note that this patch uses Mutex directly, rather than CCriticalSection.
This is because the lock-detection code is not necessarily initialized
during global constructors.
There was only one place in the codebase where we're directly reading >32 bytes from
the RNG. One possibility would be to make the built-in RNG support large reads, but
using FastRandomContext lets us reuse code better.
There is no change in behavior here, because the FastRandomContext constructor
uses GetRandBytes internally.

c8d9d9093b Fix broken notificator on GNOME (Hennadii Stepanov)
Pull request description:
Fix#14994; that bug was introduced in #14228 (that was my fault).
~Also this commit explicit separates~ There are two functions of the tray icon:
- a system tray widget (`QSystemTrayIcon::isSystemTrayAvailable() == true`)
- a high-level notificator via balloon messages (`QSystemTrayIcon::supportsMessages() == true`)
~These properties are mutually independent,~ e.g., on Fedora 29 + GNOME:
```
QSystemTrayIcon::isSystemTrayAvailable() == false;
QSystemTrayIcon::supportsMessages() == true;
```
UPDATE:
`supportsMessages()` makes no sense without `isSystemTrayAvailable()`: `QSystemTrayIcon::showMessage()` just not working on Fedora 29 + GNOME.

59e387705c test: add invalid tx templates for use in functional tests (James O'Beirne)
Pull request description:
This change adds a list of `CTransaction`-generating templates which each correspond to a specific type of invalid transaction. We then use this list to test for a wider variety of invalid tx types in `p2p_invalid_tx.py` and `feature_block.py`.
Consolidating all invalid tx types will allow us to more easily cover all tx reject cases from a variety of tests without repeating ourselves. Validation logic doesn't differ much between mempool and block acceptance, but there *is* a difference and we should be sure we're testing both comprehensively.
Right now, I've only added templates covering the tx reject types listed below but if this approach seems worthwhile I will expand the list to be fully comprehensive.

de23739b22 test: Fix rpc_net.py "pong" race condition (Ben Woosley)
Pull request description:
Prior to this change, the test fails with KeyError if pong has
a zero value at the time this is called, as getpeerinfo's
bytesrecv_per_msg result excludes zero-values.
Combined these to a single wait_until as well, which will be a bit more
forgiving re the timeout while still enforcing the same 2 seconds
overall.

Pull request description:
Salvaged (but slightly modified) from #12138, the comment there was really helpful to wrap my head around that part of the code.
In addition, a naive reader like yours truly will first think `IsValid(BLOCK_VALID_SCRIPTS)` means the previous block was invalid. But IIUC that's not what it means. Instead, it means the block hasn't been checked for validity at the `BLOCK_VALID_SCRIPTS` level yet. So in that case the existing text "previous block index isn't valid" is wrong.
