Re: [BUG] org-store-link-functions advertizes that the first non-nil return value is used, but it is not how org-store-link handles it

There are more inconsistencies. For a heading in an Org file 2 links may 
be created: title search and #custom_id. Only one link is removed by 
`org-insert-link'. Only one of them is checked if it has been stored 
earlier. Usually after several store+insert actions I have a list of 
stored links that I will never use. I am unsure what is better, to 
prompt user when link is saved, or store all options with some group ID 
and remain other links when one item from the group is inserted.

I suppose, `org-store-link' should be split into smaller building blocks 
to allow experiments with alternative implementations and strategies to 
select from several variants.

I was wrong suggestion that changing of :store property of "file" links 
may be a workaround for original issue. It is easy to store line number 
instead of search text, but there are a lot of code to detect headings, 
#custom_id, <<target>>, etc. for "file" links and this code can not be 
easily reused.
