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

Allow increasing permissions for share owner

The CSRF check in the FilesPlugin is being done to early - fixed

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

Exclude Directories

When building with "make dist", use a shortcut and only install bower
as we're not going to run any unit tests or so.

Removed more unneeded release files from composer and co.

In some cases, the owner of the share is also recipient through a group
share. The owner must still be able to increase permissions in that
situation.

Integration test on a local storage

Make dist

Makefile will rebuild if deps list changed

Prevent error with orphaned shares when updating user mount cache

Prepares a dist folder of owncloud core for release.
This updates version.php and removes all non-release files.

Allow space for federated share id search

Deps list being composer.json, etc.
Useful when switching branches and rerunning make.
