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.
89282379ba threads: fix unitialized members in sched_param (Cory Fields)
Pull request description:
Rebased theuni's #14342.
Building with gcc 8.2 against musl libc, which apparently has more attributes available in its sched_param. The following warnings were produced:
warning: missing initializer for member 'sched_param::sched_ss_low_priority' [-Wmissing-field-initializers]
warning: missing initializer for member 'sched_param::sched_ss_repl_period' [-Wmissing-field-initializers]
warning: missing initializer for member 'sched_param::sched_ss_init_budget' [-Wmissing-field-initializers]
warning: missing initializer for member 'sched_param::sched_ss_max_repl' [-Wmissing-field-initializers]
Since the current thread may have interesting non-zero values for these fields, we want to be sure to only change the intended one. Query and modify the current sched_param rather than starting from a zeroed one.

These are separate events which need to be carried out by separate subsystems.
This also cleans up some whitespace and tabs in qt to avoid getting flagged by
the linter.
Current behavior is preserved.

c3f1821ac7 Make blockdir always net specific (Hennadii Stepanov)
Pull request description:
The blocks directory is net specific by definition.
Also this prevents the side effect of calling `GetBlocksDir(false)` in the non-mainnet environment.
Currently a new node creates an unused `blocks\` directory in the root of the data directory when `-testnet` or `-regtest` is specified.

Fixes the error https://github.com/bitcoin/bitcoin/pull/14670#issuecomment-447255352 reported by @ken2812221.
There is a race between RPC stop and another concurrent call in the test framework. The connection must be established and the command `waitfornewblock` running before calling `stop`.

059a3cffdf contrib: Detailed reporting for http errors in github-merge (Wladimir J. van der Laan)
Pull request description:
Three commits I had locally for `github-merge.py`:
- *Detailed reporting for http errors in github-merge*: Print detailed error, this makes it easier to diagnose github API issues.
- *Add support for http[s] URLs in github-merge*: Sometimes it can be useful to use github-merge with read-only access (say, for reviewing and testing from untrusted VMs).
- *Allow use of github API authentication in github-merge*: The API request limit for unauthenticated requests is quite low. I started running into rate limiting errors. The limit for authenticated requests is much higher. This patch adds an optional configuration setting `user.ghtoken` that, when set, is used to authenticate requests to the API.

By adding excluded shellcheck suggestions to an array, you can avoid the current duplication
between command and comments. This ensures that they never go out of sync, makes it easier to
add new ones, and improves the readability of related diffs.

Both the chain state and the transaction pool are validation specific, but access to them is protected by two locks. The two locks have the following semantics:
* Writing to the chain state or adding transactions to the transaction pool -> Take both `cs_main` and `mempool::cs`
* Reading either or removing transactions from the the transaction pool -> Take only the appropriate lock
