This patch adds a 'check_pod_files' make target to the common make
rules, and then fixes the errors it highlighted as well as most of
the warnings. It will cause 'make check' in most of the directories to
fail if there are errors in a pod file (but not if there are warnings).

Common issues were:

  - using an '=over/=back' pair for code-like snippets that did not
    contain any =items therein; the =over keyword is intended for
    indenting lists of =item entries, and generates a warning if
    there isn't any.

  - not escaping '<' or '>'

  - blank lines that contained spaces or tabs

The second -warnings flag passed to podchecker is to add additional
warnings, un-escaped '<' and '>' being of them.

I did not fix all of the warnings in apparmor.d.pod, as I have not come
up with a good warning-free way to express the BNF of the language
similar in format to what is currently generated. The existing
libapparmor warnings (complaints about duplicate =item definition
names) are actually a result of passing the second -warnings flag.
The integration into libapparmor is suboptimal due to automake's
expectation that there will be a test driver program(s) for make check
targets; that's why I added the podchecker call to the manpage
generation point.
