In some cross-local-storage use cases, the Local storage is
instantiated with "/" as data directory. In such cases, calling
realpath() would cause PHP warnings when open_basedir is set.

This fix bypasses the realpath() call when dealing with a root storage.

Choose button remains disbaled for httpd/unix-directory

This is not correct. Hence in this patch we validate
if the mimetype is 'httpd/unix-directory'. If so we
don't disable it.

[9.2] Update some more libs

Use true random string as uri for public calendars - as a result we can no longer return the pre-publish-url

Pass web requests to occ controller if upgrade is needed

The DefaultShareProvider now does a DB-level check to find out whether
file_source is accessible at all (deleted file) or whether it's in the
trashbin of a home storage.

One small corner case where the home storage id is in md5 form cannot
be covered properly with this approach.

Fix fed share test call to return proper result

Faster Makefile dist build, less crud

Fixes an issue where retrying a previously failed federated share would
not properly reset the availability flag because the return value was
undefined instead of "true".

Use Webdav PUT for uploads

Hacked around Blueimp's jquery.fileupload to make it work with our new
chunking API.

Not needed any more in IE >= 11

- uses PUT method with jquery.fileupload for regular and public file
  lists
- for IE and browsers that don't support it, use POST with iframe
  transport
- implemented Sabre plugin to handle iframe transport and redirect the
  embedded PUT request to the proper handler
- added RFC5995 POST to file collection with "add-member" property to
  make it possible to auto-rename conflicting file names
- remove obsolete ajax/upload.php and obsolete ajax routes
