this new schema brings the new `public_id` column, which will be used to serve files via
HTTP, splits `mime_type` in 2 (`media_type` and `media_subtype`) to make indexing/media
filtering easier, and fixes indexes for `files` table.

/!\ SàT maybe be instable or some feature may not work anymore, this will improve with time
This patch port backend, bridge and frontends to Python 3.
Roughly this has been done this way:
- 2to3 tools has been applied (with python 3.7)
- all references to python2 have been replaced with python3 (notably shebangs)
- fixed files not handled by 2to3 (notably the shell script)
- several manual fixes
- fixed issues reported by Python 3 that where not handled in Python 2
- replaced "async" with "async_" when needed (it's a reserved word from Python 3.7)
- replaced zope's "implements" with @implementer decorator
- temporary hack to handle data pickled in database, as str or bytes may be returned,
to be checked later
- fixed hash comparison for password
- removed some code which is not needed anymore with Python 3
- deactivated some code which needs to be checked (notably certificate validation)
- tested with jp, fixed reported issues until some basic commands worked
- ported Primitivus (after porting dependencies like urwid satext)
- more manual fixes
the new "component file sharing management" plugin add ad-hoc commands to changes permission of one or several shared files, delete one or more files, or regenerate thumbnails.
This is a temporary plugin to make file sharing through a component usable with other entities, but should be removed (at least permission management and file deletion) in the future if we move on a pubsub based solution.
