manual,VBoxManage,isomaker/viso: Require all refsect1 and refsect2 elements to have @id attributes in manpages (refentry) to make these predictable and the split up topic files easier to handle for the docs team. Also requires these @id values to start with the refentry @id + '-'. Corrected a few bogus ones. Because 'controlvm' has too many sub-commands, HELP_SCOPE_ IDs will not be generated for 'See Also' and 'Examples' sections. bugref:10302

196 <para>The "debugvm" commands are for experts who want to tinker with the

200 software.</para>
