libselinux: man: Fix man pages formatting

- Add man page sections '(N)' to external references, and '()' on
  functions described in the same man page.
- Escape minus signs when those are expected to be used on the command
  line or files.
- Mark files and variables in italic; Note headings, function names,
  constants, program options and man page references in bold.
- Do not justify and hyphenate SEE ALSO section, and avoid hyphenation
  on symbol names by prepending them with \%.
- Remove trailing dot from NAME section description.
- Split sections with a no-op command '.', to visually distinguish them
  but to avoid introducing spurious vertical space in the formatted
  output.
- Add explicit .sp commands in the SYNOPSIS section between function
  prototypes, and fix space placement in function protoypes.
- Split header includes with .br (instead of the explicit or implicit
  .sp) so that they are vertically contiguous.
- Add missing {} around SELINUXTYPE and POLICYTYPE variable text in
  paths.
- Remove unneeded formatting commands.
- Remove spurious blank lines.
