CSP nonces are a feature available with CSP v2. Basically instead of saying "JS resources from the same domain are ok to be served" we now say "Ressources from everywhere are allowed as long as they add a `nonce` attribute to the script tag with the right nonce.
At the moment the nonce is basically just a `<?php p(base64_encode($_['requesttoken'])) ?>`, we have to decode the requesttoken since `:` is not an allowed value in the nonce. So if somebody does on their own include JS files (instead of using the `addScript` public API, they now must also include that attribute.)
IE does currently not implement CSP v2, thus there is a whitelist included that delivers the new CSP v2 policy to newer browsers. Check http://caniuse.com/#feat=contentsecuritypolicy2 for the current browser support list. An alternative approach would be to just add `'unsafe-inline'` as well as `'unsafe-inline'` is ignored by CSPv2 when a nonce is set. But this would make this security feature unusable at all in IE. Not worth it at the moment IMO.
Implementing this offers the following advantages:
1. **Security:** As we host resources from the same domain by design we don't have to worry about 'self' anymore being in the whitelist
2. **Performance:** We can move oc.js again to inline JS. This makes the loading way quicker as we don't have to load on every load of a new web page a blocking dynamically non-cached JavaScript file.

When unsharing from self in a group share situation, the share items
passed to the post_unshareFromSelf hook were using the wrong format in
which the attribute names (ex: "share_type") have non camel-case format.
This fix makes sure that in group sharing case we use the correct
format. It looks like the code was already producing it but in
array_merge it was not using it and adding the unprocessed one.

We always query the database backend. Even if we use a different one
(ldap for example). Now we do this everytime we try to get a user object
so caching that a user is not in the DB safes some queries on each
request then (at least 2 what I found).

When resolving a group share to the user group share we used to do this
on a per share basis. Now we try to do this for all group shares at
once. Of course still chunked.
Before: N incomming group shares this would mean 1 + N queries
Now: N incomming roups shares this would mean 1 + 1 queries

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.

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.

Right now a failed "copyr" will result in the error log being spammed with not really helpful error messages. Also situations such as `$dir` returning `false` are not really caught.
This adds more error handling and logging to make debugging such situations easier.

Chrome on Android has a bug that it doesn't sent cookies with the
same-site attribute for the download manager. To work around that
all same-site cookies get deleted and recreated directly. Awesome!

Often a route.php file will have many N routes but only M controllers.
Where N >= M. Which means that in most cases the ControllerName will be
converted multiple times. This is of course far from ideal.
Note that this is per app so the cache will contain at most N entries.
Which is not to bad.
In getMountPointNode function rootId is not inside of the userFolder for home storage. We was searching '/user' folder in '/user/files' folder. So, it was return NULL. I moved searching part to parent folder. It solves everything. Also, obviously other storage types not affect then this change.

* put a file without a generated preview in the trashbin
(e.g. a *.docx file)
* open the trashbin
* following errors will show up in the nextcloud.log:
- filesize(): stat failed for ...
- fopen(...): failed to open stream: No such file or directory at ...
- fread() expects parameter 1 to be resource, boolean given at ...
- fclose() expects parameter 1 to be resource, boolean given at ...
- imagecreatefromstring(): Empty string or invalid image at ...
This is because the preview code tries to load an SVG image, which
is obviously only text.
The fix simply handles this before the loading happens and the web UI
keeps showing the default mimetype icon.
Some user agents are notorious and don't really properly follow HTTP
specifications. For those, have an automated opt-out. Since the protection
for remote.php is applied in base.php as starting point we need to opt out
here.
