See `org-fold-core-region'.

The basic idea: we make use of 'invisible text property.
The value of 'invisible text property is actually set via other
properties that are linked to 'invisible via
`char-property-alias-alist'.
Links in particular are making use of a combination of two 'invisible
values: one set to be hidden via `buffer-invisibility-spec' and the other
is set to be displayed.
