Pull request description:
This PR adds binaries for 0.17, 0.18 and 0.19 to Travis and runs a basic block propagation test.
Includes test for upgrading v0.17.1 wallets and opening master wallets with older versions.
Usage:
```sh
contrib/devtools/previous_release.sh -f -b v0.19.0.1 v0.18.1 v0.17.1
test/functional/backwards_compatibility.py
```
Travis caches these earlier releases, so it should be able to run these tests with little performance impact.
Additional scenarios where it might be useful to run tests against earlier releases:
* creating a wallet with #11403's segwit implementation, copying it to an older node and making sure the user didn't lose any funds (although this PR doesn't support `v0.15.1`)
* future consensus changes
* P2P changes (e.g. to make sure we don't accidentally ban old nodes)

cb9e88e73a build: don't embed a build-id when building libdmg-hfsplus (fanquake)
Pull request description:
There was a [reproducibility issue (IRC logs)](http://www.erisian.com.au/bitcoin-core-dev/log-2020-01-25.html) with the osx `0.19.1rc1` gitian builds. The `build-id` embedded into the `dmg` tool was mismatching. It's possible that differing versions of binutils/ld were the cause.
While it was resolved after rebuilding the base gitian image, whether an upstream package issue or fluke, we can remove the possibility of it happening in future by just not embedding a build-id into the `dmg` tool at all. Can close if it's not deemed worth it.
You can test this change using the following:
```bash
# build libdmg
make native_libdmg-hfsplus_built -C depends/ HOST=x86_64-apple-darwin16 -j6 V=1
# master
readelf --string-dump .note.gnu.build-id /bitcoin/depends/work/build/x86_64-apple-darwin16/native_libdmg-hfsplus/7ac55ec64c96f7800d9818ce64c79670e7f02b67-3830944ef98/build/dmg/dmg

fa55a2554c depends: Remove reference to win32 (MarcoFalke)
Pull request description:
Closes#17504
Now that we no longer provide downloads for i686 on our website (https://bitcoincore.org/en/download/), there is no need to build them by default.
i686 can still be built in depends (tested by ci/travis) and in guix/gitian by setting the appropriate `HOSTS`.

ac57859e53 qt: Fix deprecated QCharRef usage (Hennadii Stepanov)
Pull request description:
From Qt docs:
- [`QKeyEvent::text()`](https://doc.qt.io/qt-5/qkeyevent.html#text):
> Return values when modifier keys such as Shift, Control, Alt, and Meta are pressed differ among platforms and could return an empty string.
- [`QString::operator[]()`](https://doc.qt.io/qt-5/qstring.html#operator-5b-5d):
> **Note:** Before Qt 5.14 it was possible to use this operator to access a character at an out-of-bounds position in the string, and then assign to such a position, causing the string to be automatically resized. Furthermore, assigning a value to the returned `QCharRef` would cause a detach of the string, even if the string has been copied in the meanwhile (and the `QCharRef` kept alive while the copy was taken). These behaviors are deprecated, and will be changed in a future version of Qt.
Since Qt 5.14 this causes a `QCharRef` warning if any modifier key is pressed while the splashscreen is still displayed.
Fix#18080.
Note: Ctrl+Q will also close the spashscreen now.

Pull request description:
This updates leveldb to currently newest upstream commit 0c40829872:
- CRC32C hardware acceleration is now an external library [crc32c](https://github.com/google/crc32c). This adds acceleration on ARM, and should be faster on x86 because of using prefetch. It also makes it easy to support similar instruction sets on other platforms in the future.
- Thread handling uses C++11, instead of platform specific code.
- Native windows environment was added. No need to maintain our own hacky one, anymore.
- Upstream now builds using CMake. This doesn't mean we need to use that (phew), but internal configuration changed to a a series of checks, instead of OS profiles. This means the blanket error "Cannot build leveldb for $host. Please file a bug report' is removed.
All changes: a53934a3ae...0c40829872
Pretty much all our changes have been subsumed by upstream, so we figured it was cleaner to start over with a new branch from upstream with the still-relevant patches applied: https://github.com/bitcoin-core/leveldb/tree/bitcoin-fork-new
There's quite some testing to be done (see below). See https://github.com/bitcoin-core/leveldb/issues/25 and https://github.com/bitcoin-core/leveldb/pull/26 for more history and context.

acd644b83d build: remove --large-address-aware linker flag (fanquake)
Pull request description:
This flag was used when building 32-bit Windows executables, which we no-longer
do, and is not accepted by the linker for any of the hosts we currently build
for. i.e:
```bash
checking whether the linker accepts -Wl,--large-address-aware... no
```
--large-address-aware
If given, the appropriate bit in the "Characteristics" field of the COFF
header is set to indicate that this executable supports virtual addresses
greater than 2 gigabytes. This should be used in conjunction with the /3GB
or /USERVA=value megabytes switch in the "[operating systems]" section of
the BOOT .INI. Otherwise, this bit has no effect. [This option is specific
to PE targeted ports of the linker]
You can check that the appropriate bit in the COFF header of our 64-bit
Windows binaries is still be set using dumpbin. i.e:
```powershell
dumpbin /headers .\bitcoind.exe
FILE HEADER VALUES

c0bc453135 build: remove deprecated key from macOS Info.plist (fanquake)
Pull request description:
Note that the current release binaries show correct version numbers everywhere in the GUI and macOS info dialogs (except for when you "space" click the app, shown in screenshots), and we haven't reintroduced the issue that #14701 fixed. This is just swapping a deprecated field for a newer one, as well as using the entire version string in two fields that we hadn't been previously.
Follows up discussion in #14701.
0.19.0.1

Pull request description:
Here are a few things to improve in the asmap implementation. The first two commits are just code improvements. The last one is a bugfix (the exsting code wouldn't correctly apply ASN lookups to mapped/embedded IPv4 addresses).

Pull request description:
<!--
*** Please remove the following help text before submitting: ***
Pull requests without a rationale and clear improvement may be closed
immediately.
-->
<!--
Please provide clear motivation for your patch and explain how it improves
Bitcoin Core user experience or Bitcoin Core developer experience
significantly:
* Any test improvements or new tests that improve coverage are always welcome.
* All other changes should have accompanying unit tests (see `src/test/`) or
functional tests (see `test/`). Contributors should note which tests cover
modified code. If no tests exist for a region of modified code, new tests
should accompany the change.
* Bug fixes are most welcome when they come with steps to reproduce or an
explanation of the potential issue as well as reasoning for the way the bug
was fixed.
* Features are welcome, but might be rejected due to design or scope issues.
If a feature is based on a lot of dependencies, contributors should first
consider building the system outside of Bitcoin Core, if possible.
* Refactoring changes are only accepted if they are required for a feature or
bug fix or otherwise improve developer experience significantly. For example,
most "code style" refactoring changes require a thorough explanation why they
are useful, what downsides they have and why they *significantly* improve
developer experience or avoid serious programming bugs. Note that code style
is often a subjective matter. Unless they are explicitly mentioned to be
preferred in the [developer notes](/doc/developer-notes.md), stylistic code
changes are usually rejected.

When bitcoind is running in pruned mode, producing a hashlist with `./linearize-hashes.py linearize.cfg > hashlist.txt` and then executing `linearize-data.py linearize.cfg` will produce:
```
Read 313001 hashes
Input file /home/dan/.bitcoin/blocks/blk00000.dat
Premature end of block data
```
This happens because `linearize-data` starts by attempting to process `blk00000.dat` regardless of whether or not `blk00000.dat` actually exists - this may not be the case if working with a pruned node.
This PR adds a function which finds the first block file that does exist, and calls that function when the `BlockDataCopier` is initialized.
This is a refactor of #16431.
<!--
Bitcoin Core has a thorough review process and even the most trivial change
needs to pass a lot of eyes and requires non-zero or even substantial time
effort to review. There is a huge lack of active reviewers on the project, so
patches often sit for a long time.

1abcecc40c Tests: Use self.chain instead of 'regtest' in almost all current tests (Jorge Timón)
Pull request description:
Simply avoiding the hardcoded string in more places for consistency.
It can also allow for more easily reusing tests for other chains other than regtest.
Separated from #8994 .
Continues #16509 .
It is still not complete (ie to be complete, we need the -chain parameter in #16680 and make whether acceptnonstdtxs is allowed for that chain or not customizable for regtest [or for custom chains like in #8994 ] ). But while being incomplete like #16509 , it's quite simple to review and another step forward IMO.

Sjors:
re-ACK 1abcecc. I think it's an improvement even if incomplete and if some PR's might accidentally bring "regtest" back. Subsequent improvements hopefully don't have to touch 16 files.
