Pull request description:
Avoid logging `IsBerkeleyBtree: No such file or directory ...`. The result of `IsBerkeleyBtree` is the same since `fs::file_size()` returns 0 for non existent files.

4ddeb2f860eee98fbe94725ea8885368068a03f2 GUI: Options: Set the range of pruning size before loading its value (Luke Dashjr)
Pull request description:
This fixes two bugs:
1. The prune setting range was set *after* loading the current value. If users had a prune of (eg) 200, it would get limited to 99 before the range was raised. This is fixed by setting the range first.
2. The prune setting was limited to <= the chainparams' "assumed blockchain size". There's no reason for this limit (the UX is the same either way), and there are use cases it breaks (eg, setting a prune size such that it begins pruning at some future point). Therefore, I raised it to the max value.
This is a daggy fix, so should cleanly merge to both master and 0.18 branches.

Pull request description:
This does not remove OpenSSL, but makes our own PRNG the 'main' one; for GetStrongRandBytes, the OpenSSL RNG is still used (indirectly, by feeding its output into our PRNG state).
It includes a few policy changes (regarding what entropy is seeded when).
Before this PR:
* GetRand*:
* OpenSSL
* GetStrongRand*:
* CPU cycle counter
* Perfmon data (on Windows, once 10 min)
* /dev/urandom (or equivalent)
* rdrand (if available)
* From scheduler when idle:
* CPU cycle counter before and after 1ms sleep
* At startup:
* CPU cycle counter before and after 1ms sleep
After this PR:
* GetRand*:
* Stack pointer (which indirectly identifies thread and some call stack information)
* rdrand (if available)
* CPU cycle counter
* GetStrongRand*:
* Stack pointer (which indirectly identifies thread and some call stack information)
* rdrand (if available)
* CPU cycle counter
* /dev/urandom (or equivalent)
* OpenSSL
* CPU cycle counter again
* From scheduler when idle:
* Stack pointer (which indirectly identifies thread and some call stack information)
* rdrand (if available)
* CPU cycle counter before and after 1ms sleep
* Perfmon data (on Windows, once every 10 min)
* At startup:
* Stack pointer (which indirectly identifies thread and some call stack information)
* rdrand (if available)
* CPU cycle counter
* /dev/urandom (or equivalent)
* OpenSSL
* CPU cycle counter again
* Perfmon data (on Windows, once every 10 min)
The interface of random.h is also simplified, and documentation is added.
This implements most of #14623.

fa6ab8ada1 rpc: Return more specific reject reason for submitblock (MarcoFalke)
Pull request description:
The second commit in #13439 made the `TODO` in the first commit impossible to solve.
The meaning of `fNewBlock` changed from "This is the first time we process this block" to "We are about to write the new *valid* block".
So whenever `fNewBlock` is true, the block was valid. And whenever the `fNewBlock` is false, the block is either valid or invalid. If it was valid and not new, we know it is a `"duplicate"`. In all other cases, the `BIP22ValidationResult()` will return the reason why it is invalid.

8f5d9431a Add regtests for HTTP status codes. (Daniel Kraft)
Pull request description:
This adds explicit tests for the returned HTTP status codes to `interface_rpc.py` (for error cases) and the HTTP JSON-RPC client in general for success.
#15381 brought up discussion about the HTTP status codes in general, and the general opinion was that the current choice may not be ideal but should not be changed to preserve compatibility with existing JSON-RPC clients. Thus it makes sense to actually test the current status to ensure this desired compatibility is not broken accidentally.

8b8d8eeae9 Remove travis_wait from lint script (Graham Krizek)
Pull request description:
Using the `travis_wait` command in conjunction with `set -o errexit` causes problems. The `travis_wait` command will correctly log the command's output if successful, but if the command fails the process exits before the `travis_wait` command can dump the logs. This will hide important debugging information like error messages and stack traces. We ran into this in #15196 and it was very hard to debug because output was being suppressed.
`travis_wait` was being used because the `contrib/verify-commits/verify-commits.py` script can sometimes run for a long time without producing any output. If a script runs for 10 minutes without logging anything, the CI run times out. The `travis_wait` command will extend this timeout by logging a message for you, while sending stderr and stdout to a file.
This PR removes the `travis_wait` command from our CI system and adds additional logging to the `verify-commits.py` script so it doesn't make Travis timeout.

3fb09b9889665a24b34f25e9d1385a05058a28b7 Warn unrecognized sections in the config file (Akio Nakamura)
Pull request description:
This PR intends to resolve#14702.
In the config file, sections are specified by square bracket pair "[]"$,
or included in the option name itself which separated by a period"(.)".
Typicaly, [testnet] is not a correct section name and specified options
in that section are ignored but user cannot recognize what is happen.
So, add some log-warning messages if unrecognized section names are
present in the config file after checking section only args.
note: Currentry, followings are out of scope of this PR.
1) Empty section name or option name can describe.
e.g. [] , .a=b, =c
2) Multiple period characters can exist in the section name and option name.
e.g. [c.d.e], [..], f.g.h.i=j, ..=k

Pull request description:
This might increase coverage, but more importantly this checks that the node doesn't crash when generating the help. (Right now the help is a static string, but in the future it might be generated at runtime)

Pull request description:
* Use `ToLower(...)` instead of `std::tolower`. `std::tolower` is locale dependent.
* Use `IsDigit(...)` instead of `std::isdigit`. Some implementations (e.g. Microsoft in 1252 codepage) may classify single-byte characters other than `[0-9]` as digits.
* Update `KNOWN_VIOLATIONS`: Remove fixed violations.
* ~~Replace use of locale dependent Boost trim (`boost::trim`) with locale independent `TrimString`.~~
* Use` IsSpace(...)` instead of `boost::is_space`
