documentation: rewrite for shared in free

Browse Source 
Minor tweaks in the free manual page
* Removed author section. It's wrong and strongly discouraged
  by the man page standards.
* Moved note about shared not in old kernels into bugs sections
as this is not relevant for most people and declutters the top
sections.
