Bug#644169: libapache2-mod-perl2: PerlOptions -Sections not permitted in server config, but should be

[Jan Ingvoldstad]

Here is a patch that ensures that <Perl> (and Pod) sections are only
allowed in the server configuration and not per directory, which
incidentally matches the specification table here:

http://perl.apache.org/docs/2.0/user/config/config.html#mod_perl_Directives_Argument_Types_and_Allowed_Location

The patch has been tested on the same system where I identified the
problem.

The patch solves the issue for me, and leaves only the following
issues, as far as I can tell:

 - Should there be fine-grained control as "PerlOptions -Sections"
   implies or not?

 - The mod_perl documentation (online and in the module) probably
   needs to be changed to reflect that PerlOptions -Sections does not
   work.
