* Add versioned inline namespace Add a versioned inline namespace to prevent ABI issues when linking code using multiple library versions. * Add namespace macros * Encode ABI information in inline namespace Add _diag suffix to inline namespace if JSON_DIAGNOSTICS is enabled, and _ldvcmp suffix if JSON_USE_LEGACY_DISCARDED_VALUE_COMPARISON is enabled. * Move ABI-affecting macros into abi_macros.hpp * Move std_fs namespace definition into std_fs.hpp * Remove std_fs namespace from unit test * Format more files in tests directory * Add unit tests * Update documentation * Fix GDB pretty printer * fixup! Add namespace macros * Derive ABI prefix from NLOHMANN_JSON_VERSION_*
