6ce2f35ba8 Fix outputting extreme integer values in edge cases 
For some gcc version (Ubuntu 5.5.0-12ubuntu1~16.04) the existing code
crashes when the minimum value of int64_t is outputted.

Resurrect the code from before 546e2cbf (🚨 fixed some warnings,
2019-03-13) but delegate the sign removal so that the compilers don't
complain about taking the negative value of an unsigned value.

In addition we also rewrite the expression so that we first increment
and then negate.

The definition of remove_sign(number_unsigned_t) is never called as
unsigned values are never negative.

The important thing to note here is that a std::valarray is *not* a STL
container, so the usual containter and iterator semantics don't apply.

Therefore we have to check if the container is non-empty before.

61fe5f1eee input_buffer_adapter: Fix handling of nullptr input 
Clang UBSAN currently complains that the char * to input_buffer_adapter
is a nullptr.

Turns out it is actually required to accept nullptr, see for example
line 415 in input_adapters.hpp

  ...
  // the address of first cannot be used: use nullptr
  ia = std::make_shared<input_buffer_adapter>(nullptr, len);
  ....

Therefore we have to handle it gracefully here. We now also ignore the
length parameter l if b is a nullptr.

f4fca2d59a Fix #1642 
While in our case, only the string case was affected, to be safe and allow the library to work with other unforeseen cases, all of the cases have been wrapped with parentheses.

Thank you @DyXel and @edo9300

5ccdaf643f Remove C++17 extension warning from clang; #1535 
- Switch off `nodiscard` for clang unless C++17 is detected.
- Detect C++ standard before the switch.
