man pages - consistency fixes

podman-generate and -play had the wrong NAMEs.

podman-restart and -volume-prune the wrong SYNOPSIS.

All the rest are varying degrees of minor:

  - missing a space between the NAME and description
  - multi-line SYNOPSIS that could be collapsed into one
  - use of UPPER CASE in synopsis instead of *asterisks*
  - improper use of **double asterisks** for options
  - varlink and version were transposed in podman-1
  - fixed inconsistencies between the description in
    the man page and that in the parent manpage. These
    are too numerous for me to fix all.

Added: script that could be used in CI to prevent future
such inconsistencies. It cannot be enabled yet because
there are still 35+ inconsistencies in need of cleaning.

This will be difficult to review on github. I suggest
pulling the PR and running 'git log -1 -p | cdif | less'

'cdif' is a handy tool for colorizing individual diffs between
lines:

There are other such tools; use your favorite. Comparing
without visual highlights may be painful.

I also encourage you to run hack/man-page-checker and suggest
more fixes for the problems it's finding.
