* build: Fix `--enable-glibc-back-compat`
Compiling on Ubuntu 20.04 results in binaries that can't be run on older systems we still support (e.g. Ubuntu 16.04) and `contrib/devtools/symbol-check.py` complains about it.
Available versions for `log` for example:
$ objdump -T /lib/x86_64-linux-gnu/libm.so.6 | egrep -w 'log'
00000000000431b0 g DF .text 0000000000000039 GLIBC_2.29 log
0000000000012360 g DF .text 0000000000000066 (GLIBC_2.2.5) log
(i.e. the default one is 2.29)
This commit fixes the issue by picking the version we support instead of the default one.
Before:
$ objdump -T dashd | egrep -w 'log'
0000000000000000 DF *UND* 0000000000000000 GLIBC_2.29 log
After:
$ objdump -T dashd | egrep -w 'log'
0000000000000000 DF *UND* 0000000000000000 GLIBC_2.2.5 log
* ci: Add `make check-symbols` to the `build` step
* ci: Do not specify `--enable-glibc-back-compat` for non-release builds
* ci: Set correct LDFLAGS for the release build
* doc: Update docs to mention the need for `LDFLAGS=-static-libstdc++` when compiling for same host but different distro
* ci: Add `--with-sanitizers=undefined` back to `linux64` build
c4606b84329d760d7cee144bebe05807857edaae Add Travis check for single parameter constructors not marked "explicit" (practicalswift)
Pull request description:
Make single parameter constructors `explicit` (C++11).
Rationale from the developer notes:
> - By default, declare single-argument constructors `explicit`.
> - *Rationale*: This is a precaution to avoid unintended conversions that might
> arise when single-argument constructors are used as implicit conversion
> functions.

Pull request description:
This PR is extracted from https://github.com/bitcoin/bitcoin/pull/13816 to make that one easier to review. It follows on https://github.com/bitcoin/bitcoin/pull/13849 and https://github.com/bitcoin/bitcoin/pull/13851
In here the shell script parts from `travis.yml` are extracted into `.travis/before_install.sh`, `.travis/install.sh`, `.travis/before_script.sh`, `.travis/script.sh`, and `.travis/lint.sh`.
This has the benefit that `test/lint/lint-shell.sh` will also shellcheck these parts. Also it makes the individual script parts more readable.

fa3c910bfeab00703c947c5200a64c21225b50ef test: Move linters to test/lint, add readme (MarcoFalke)
Pull request description:
This moves the checks and linters from `devtools` to a subfolder in `test`. (Motivated by my opinion that the dev tools are mostly for generating code and updating the repo whereas the linters are read-only checks.)
Also, adds a readme to clarify that checks and linters are only meant to prevent bugs and user facing issues, not merely stylistic preference or inconsistencies. (This is motivated by the diversity in developers and work flows as well as existing code styles. It would be too disruptive to change all existing code to a single style or too burdensome to force all developers to adhere to a single style. Also note that our style guide is changing, so locking in at the wrong style "too early" would only waste resources.)

* GCC-7 and glibc-2.27 compat code
* Statically link libstdc++ for GCC based builds
Makes sure binaries which are built on a newer build host still work
on older distros.
* Use python3 when installing MacOS native tools
* Move actual build logic out of Travis and upgrade to gcc-7
Travis will now simply call a few scripts which do the actual work.
These scripts will first create a "builder image" which contains the
necessary environment for the actual build. Then scripts are called
inside this builder image to do the build.
This should make us more independant from Travis and also allows us
to do local CI testing.
The build matrix is also moved out of .travis.yml and instead moved
into ci/matrix.sh. This script is sourced with only "BUILD_TARGET" being
set so that it internally can figure out which other environment
variables need to be set.
This commit also upgrades the used GCC version to 7. This is due to the
use of ubuntu:bionic as base image for the builder image.
* Add Jenkinsfiles for regular CI and nightly gitian builds
* Automatically download OSX SDK in gitian-build.sh
* Remove bogus "export MAKEJOBS=-j5"
* Forward cache/src dirs into builder container
Fixes caching issues on Travis.
* fix
* Fail build immediately when building depends took too long
