Modified Files:
        src/lib/libc/gen: err.3

Log Message:
Make the err(3) manual clearer to read.

- Mention that the 'fmt' argument to these functions holds
  a printf(3)-like format specification.
- Clarify that the err()/warn()/errc()/warnc() family of functions
  will append an additional error message to the output.
- Add whitespace to separate paragraphs describing distinct
  concepts.
- Move the sentence mentioning the final output newline to
  a less ambiguous location within the text.
- Add a cross-reference to printf(3).
