netlist: fix bug, prepare for future changes and improve readability (#9947)
* netlist: fix bug, prepare for future changes and improve readability
- fix a bug where a net processing error may trigger a nullptr access
- applied some clang-tidy recommendations
- add no_return to plib::terminate
- properly encapsulate dynamic_cast usage
- more review of noexcept
- added a clang-format file. Over time, all source files will be
processed with clang-format
- Used clang format on a number of files
- Rewrote 74174
- all device constructors now use a struct to pass data on
to base classes. Neither netlist state nor the name are intended
to be used in a constructor. After the base class was
constructed, they can be accessed by state() and name().
- The device construction macros can now be removed. Changes to
the core will not need to be reflected in constructors.
- Change truth table macros so that going forward NETLIST_END and
TRUTH_TABLE_END can be replaced by a closing curly brace. netlists can
than use curly braces enclosed blocks.
- more clang-format
- removed some macros completely
- all derived classes from base_device_t now don't use macros
any longer.
- as a result, delegator_t was removed. This class was only used
to support macros :-(
