Re-implemented plow setup for the first time since about 2006, enabling the "plow" command. At this time, however, not all rules are being implemented correctly given the numerous changes to the DRC handling since the last time "plow" was working. Fixes are ongoing.

Compatibility with C99 standard This commit makes the code (mostly) C99-compatible, enabling to compile it without the -Wno-error=implicit-function-declaration flag. This way, Magic becomes usable on arm64 architectures, specifically on Apple computers with M1/M2 SoC.
