doc: unify definition list usage across man pages

Make all parameter descriptions etc. use reStructuredText definition
lists with uniform style and indentation. Remove redundant indentation
from around the lists. Remove blank lines between term lines and
definition blocks. Use four spaces for indentation.

This is almost completely whitespace and paragraph reflow changes.
