(org-id-link-use-context): New option to add context to org-id links.
(org-id-get): Add optional `inherit' argument which considers parents'
IDs if the current entry does not have one.

when current heading has no ID and `org-id-link-consider-parent-id' is
set. Add a search string to the link when enabled.
(org-id-store-link-maybe): Function set as :store option for custom id
link property. Move logic from `org-store-link' here to determine when
an org-id link should be stored using `org-id-store-link'.
(org-id-open): Recognise search strings after "::" in org-id links.
* lisp/org-lint.el: Add checker for "::" in ID properties.
* testing/lisp/test-ol.el: Add tests for

These feature allows for more precise links when using org-id to link to
org headings, without requiring every single headline to have an id.
