0c78e49be3 tests: Switch one of the Travis jobs to an unsigned char environment (-funsigned-char) (practicalswift)
Pull request description:
Switch one of the Travis jobs to an unsigned char environment (`-funsigned-char`).
This will help us catch errors due to code written under the assumption that `char` has the same value range as `signed char`.
The signedness of `char` is implementation-defined.
Example:
```
$ uname -a
Linux […] x86_64 x86_64 x86_64 GNU/Linux
$ cat foo.cpp
#include <iostream>
int main() {
char c;
std::cin >> c;
int i = (unsigned char)c;
std::cout << i << "\n";
}
$ clang++ -o foo foo.cpp
$ echo -e "\xff" | ./foo
255
$ clang++ -fsigned-char -o foo foo.cpp
$ echo -e "\xff" | ./foo
255
$ clang++ -funsigned-char -o foo foo.cpp
$ echo -e "\xff" | ./foo
255
$ cat bar.cpp
#include <iostream>
int main() {
char c;
std::cin >> c;
int i = c;
std::cout << i << "\n";
}
$ clang++ -o bar bar.cpp
$ echo -e "\xff" | ./bar
-1
$ clang++ -fsigned-char -o bar bar.cpp
$ echo -e "\xff" | ./bar
-1
$ clang++ -funsigned-char -o bar bar.cpp
$ echo -e "\xff" | ./bar
255
```
`gcc` chars:
* signed: alpha, hppa, ia64, m68k, mips, sh, sparc, x86
* unsigned: arm, powerpc, s390
About `-funsigned-char`:
> Let the type "char" be unsigned, like "unsigned char".
>
> Each kind of machine has a default for what "char" should be. It is either like "unsigned char" by default or like "signed char" by default.
>
> Ideally, a portable program should always use "signed char" or "unsigned char" when it depends on the signedness of an object. But many programs have been written to use plain "char" and expect it to be signed, or expect it to be unsigned, depending on the machines they were written for.
>
> This option, and its inverse, let you make such a program work with the opposite default. The type "char" is always a distinct type from each of "signed char" or "unsigned char", even though its behavior is always just like one of those two.

fa83999d92 travis: Compile once on trusty (MarcoFalke)
Pull request description:
To avoid accidentally regressing again on #15172, we should compile at least once with gcc4.8 (the minimum required version)
Note that this uses the trusty image, which will be removed in a few months from the docker hub, so in the future it had to be switched to the centos7 (or similar) image, which should come with gcc4.8 as well.

Make lint/check-doc.py Python 3.4 compatible.
Also add .python-version for pyenv which will cause tests with too
modern syntax to fail on developer machine rather than on Travis.
d3ecc3d695 travis: Save cache on build error (Chun Kuan Lee)
Pull request description:
In current travis setup, the job will terminate immediately if an error occur. There is no chance to save the cache. This was accidentally introduced by #13863. This PR is to fix the issue and travis would save cache on error.

Pull request description:
Dry run `bench_bitcoin` (`-evals=1 -scaling=0`: <1 second running time) as part `make check` to allow for quick identification of assertion/sanitizer failures or crashes in benchmarking code.
This is already tested in Travis but it is nice to have it locally too. The cost is near zero.
