* Removed the space used by the left navbar when it has no children (xwiki standard's default)

  * Fix wrong deprecated annotation

* Reduced visibility of the separators between fields

Hacking the Edit menu was needed initially when we developed the CKEditor Integration (before we added support for selecting CKEditor as default WYSIWYG editor). We kept the hack while the code was in xwiki-contrib because we were supporting older versions of XWiki.

* Removed the bootstrap grid from the card on the Help Home page
* Added style to the new card elements
* Added a couple classes to force the number of columns
* Updated structure on other pages of the help section.
* Used bootstrap 3 variables

* Update the structure of the LiveData dropdown (namely, removed separator <li>s and grouped links together) to improve accessibility
* Update bootstrap dropdown styles to account for this new kind of separator in dropdowns.

* Layout updated with list elements
* Simplified the architecture of the page content (notably replaced a clearfix hack with a flex)

  * Provide methods to allow querying document based on case sensitive
    tag
  * Use that method to get list of documents based on case sensitive tag
   when renaming a tag to change its case only to preserve backward
compat of renaming
  * Refactoring of existing PO for integration test and cover the
    scenario in a new integration test
  * Minor fixes

* Introduce a new `SimpleDocumentCache` for caching values associated with document references.
* Use the cache in the `DocumentRequiredRightsManager`.
* Return static instances in `DocumentRequiredRightsReader` to reduce the memory usage of the cache.
* Remove `DocumentRequiredRightsManager` from the page test component list and instead add a mock in `MockitoOldcore`.
* Move `DocumentRequiredRightsManager` to the authorization bridge as it fits better there and with the mock implementation in `MockitoOldcore` there is no need to have it available for tests.

[misc] Put back the revapi excludes removed by the release script, that were introduced after 16.10.0RC1

* Fix parent version after cherry-pick

* Adapt Rendering tests located in platform

* Update dependency after refactoring the xwiki-platform-uiextension-api module.

* Fix cycle in dependecy chain by extracting code that depends on oldcore from uiextension-api in a new uiextension-default.
