3e0df92bf2 Update with new Windows code signing certificate (Andrew Chow)
Pull request description:
The current Windows code signing certificate is about expire (on March 26th 2020). As I have volunteered to take over the Windows code signing duties, I've purchased a new Windows code signing certificate with the same CA and under the same organization (Bitcoin Core Code Signing Association).
A signature by the old certificate over the new certificate has been provided to me. This signature can be verified using
```
openssl cms -verify -inform pem -purpose any -content path/to/new/win-codesign.cert -CAfile path/to/old/win-codesign.cert -certfile path/to/old/win-codesign.cert
```
The verification should succeed and the new certificate will be printed out. This can be compared to the contents of `win-codesign.cert`.
```

The idea is clear described by some developers:

> This whole concept of explicitly listing each and every file manually (or with a fragile wildcard) is an obvious sisyphean task. I'd say all we need to do is run git archive and be done with it forever, see #16734, #6753, #11530 ...
- [laanwj](https://github.com/bitcoin/bitcoin/pull/17097#issuecomment-540706025):
> I agree, I've never been a fan of it. I don't think we have any files in the git repository we don't want to ship in the source tarball.

The suggested changes have a downside which is pointed by [**luke-jr**](https://github.com/bitcoin/bitcoin/pull/17104#issuecomment-540828045):
> ... but the distfile needs to include autogen-generated files.
This means that a user is not able to run `./configure && make` right away. One must run `./autogen.sh` at first.
Here are opinions about mandatory use of `./autogen.sh`:
- [ryanofsky](https://github.com/bitcoin/bitcoin/issues/16734#issuecomment-534139356):
> It's probably ok to require autogen. I think historically configure scripts were supposed to work on obscure unix systems that would just have a generic shell + make tool + c compiler, and not necessarily need gnu packages like m4 which are needed for autogen.
- [laanwj](https://github.com/bitcoin/bitcoin/issues/16734#issuecomment-540729483):
> I also think it's fine to require autogen. What is one dependency more, if you're building from source.

Previously, Guix would produce a gcc which did not know to use the SSP
function from glibc, and required a gcc make flag for it to do so, in my
attempt to fix it upstream I realized that this is no longer the case.
This can be verified by performing a Guix build and doing
readelf -s ... | grep __stack_chk
to check that symbols are coming from glibc, and doing
readelf -d ... | grep NEEDED | grep ssp
to see that libssp.so is not being depended on

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`.

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.

- [x] Subtree `crc32c`

*** Please remove the following help text before submitting: ***
Pull requests without a rationale and clear improvement may be closed

<!--
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.

b3c4d9bac6 test: rename test suite name "tx_validationcache_tests" to match filename (Sebastian Falbesoner)
Pull request description:
Quoting `src/test/README.md`, '`Adding test cases`':
> "The file naming convention is `<source_filename>_tests.cpp`

> called `<source_filename>_tests`."
Currently the unit test source file `txvalidationcache_tests.cpp` contains a unit test suite with the name `tx_validationcache_tests`, which is fixed by this PR. The following shell script shows that this is the only mismatch and for all other unit test source files the test suite names are correct:
```
#!/bin/bash
shopt -s globstar
for test_full_filename in **/*_tests.cpp; do
test_name_file=`basename $test_full_filename .cpp`
test_name_suite=`sed -n "s/^.*TEST_SUITE(\(.*_tests\).*$/\1/p" $test_full_filename`
if [ $test_name_file != $test_name_suite ]; then

88c83636d5 guix: Update documentation for time-machine (Carl Dong)
e6050884fd guix: Pin Guix using `guix time-machine` (Carl Dong)
Pull request description:
An alternative to #16519, pinning our version of Guix and eliminating a `guix pull` and changing the default Guix profile of builders.
I think this method might be superior, as it:
- Eliminates the possibility of future changes to the `guix environment` command line interface breaking our builds
- Eliminates the need to set up a separate channel repo
It is a more general pinning solution than #16519.
-----
The reason why I didn't originally propose this is because `guix time-machine` is a recent addition to Guix, only available since `f675f8dec73d02e319e607559ed2316c299ae8c7`

This adds dynamic library checks for MACHO executables to symbol-check.py. The script has been modified to function more like `security-check.py`. The error output is now also slightly different. i.e:
```bash

fae75306ba scripted-diff: Set gitian arch back to amd64 (MarcoFalke)
Pull request description:
This was required to allow gitian builds on non-amd64 architecture, however, it seems to break the current builds (with lxc), see https://github.com/bitcoin/bitcoin/pull/17409#issuecomment-554099626
Also, the gititan builds wouldn't be deterministic across arches anyway, see #17468
So instead of wasting more time on this, revert the change and hope that guix allows to compile on non-amd64 architectures.

Pull request description:
Updated the example-linearize.cfg file to include support for the regtest chain network config which is used by the ./linearize-data.py
Problem:
Without the regtest magic, genesis hash and path config, the `linearize-data.py` script cannot generate a bootstrap.dat file.
Example:
./linearize-data.py ./linearize.cfg
Read 102 hashes
Genesis block not found in hashlist
Solution:
Added netmagic, genesis and input example parameters to file.
Resolution
1. Starting bitcoind in regtest mode
2. bitcoin-cli generatetoaddress 101 $(bitcoin-cli getnewaddress)
3. ./linearize-hashes.py ./linearize.cfg > ./hashlist.txt
4. ./linearize-data.py ./linearize.cfg
```
$ ./linearize-data.py ./linearize.cfg
Read 102 hashes
Input file /Users/gr0kchain/.bitcoin/regtest/blocks/blk00000.dat

c966ff14c7 gitian: fixed SC2001 regex (willyk)
Pull request description:
Currently the gitian-win-signer.yml produces OUTFILE names without `-unsigned` stripped out
This is due to regex having an`%` in front of it
```
$ INFILE="bitcoin-0.19.0-win64-setup-unsigned.exe"
$ echo "${INFILE/%-unsigned}"
bitcoin-0.19.0-win64-setup-unsigned.exe
$ echo "${INFILE/-unsigned}"
bitcoin-0.19.0-win64-setup.exe
```
