Patch with list of wrong links and typos in E N doc

Dear colleagues,    
 
When I did translation of all documents, I prepared the list of all met mistakes,
that I recognised in the original English text (most of them — wrong links due to
changes in the document structure in last years).
 
I prepared the review  https://reviews.freebsd.org/D52435
If you look at it, you see, that all changes are trivial (as stated in the Committer guide —
typos or links errors).
 
Could you consider and commit them to increase the quality of the original documentation
and cascade the changes into translated documentation via Weblate?
 
Best regards,
