* Fix a precision bug of valueToString, prevent to give an error result on input of wanted precision 0 and a double value which end of zero before decimal point ,such as 1230.01,12300.1;
Add test cases for double valueToString with precision 0;

* Delete a test case with platform differences in the previous commit

* Fix clang-format.

* Fix clang-format!

* ENH: Prevent cmake in source builds

Building directly inside the root of the source tree
can cause problems where the build intermediate files
overwrite or conflict with the intended source code
files.

This modification identifies this problem and
issues failure messages and suggestions to over
come the problem with more robust build suggestion.

Try meson/ninja from pypi

This lets us simplify linux a little.

However, we still want to test cmake, so there is only so much we
can simplify.

For OSX, we still need `clang-format` from homebrew.

* Add PYTHONUSERBASE/bin to PATH for linux

Fixes: #1224

Not all distributions provide Python as python3 and as Meson already depends on 3.5+ just use what Meson uses.

Fix #1197 

* BUILD_TYPE corresponds to Release/Debug
   but LIB_TYPE corresponds to shared/static.

* Add support to build shared, static and object lib at the same time.

This patch adds an explicit ctor with a std::nullptr_t argument, that is `delete`-d. This keeps Json::Value from exposing a coding error when automatically promoted to a const char* type.

* avoid isprint

`std::isprint` is locale-specific and the JSON-spec is not.
In particular, isprint('\t') is true in Windows CP1252.

Has bitten others, e.g. https://github.com/laurikari/tre/issues/64



Fixes #1187

* semicolon (rookie mistake!)

* Windows tab escape testing with custom locale (#1190)

* semicolon (rookie mistake!)

This patch fixes a fuzzing bug by resolving a bad fallthrough in the
setComment logic.

The result is that we get a proper error instead of an assert, making
the library friendlier to use and less likely to cause issue for
consumers.

Improve CMake correctness and handling

This is already covered by the toplevel CMake, which also serves to
provide a consistent minimum version.

Commit aebc7faa added version checks for CMake compatibility. In reality,
only the add_compile_definitions need the check - add_compile_options
itself has been supported since 3.0. Tested and confirmed built
successfully with CMake 3.8.0.

EXTRA_CXX_FLAGS is never defined, making this a noop. Further,
COMPILE_OPTIONS is invalid to set as a DIRECTORY property.
