Same CLI as pw-dump, i.e. -N, --no-colors, --color=always etc are
supported.

This uses a for-loop macro hack to automatically print prefixes and
suffixes, the with_prefix() macro resolves into the correct printf
statements to insert either just the marker "*" or the ansi sequences
for color/reset. Use of the macro is simply:
```
   with_prefix(true, stderr) {
	fprintf(stderr, "this will be prefixed\n");
   }
```
