doc: make the library API pages a little more readable

Use of the the '.B' and '.BI' man documentation macros
had rendered the three library API pages less readable
than they could be. In addition, sometimes the pointer
indicator and an identifier were separated by a space.

So, this commit will trade those macros for some '.RI'
and '.RB' macros plus treat the pointers consistently.

[ plus we no longer italicize sort 'stacks' brackets ]
