API, let's make sure we don't try to talk to a server with an older API.

Turns out that when we added a new e2e folder during sync, we were
passing the wrong path to the e2e object. We have several path
convention in the sync code, just happened to be the wrong one.
I still long for the day when we'll use the type system to deal with
paths. All those strings are error-prone.

metadata associated to them, so let's get ready to handle it. In case of
a 404 to get the metadata, we create an empty metadata payload and pass

With the current design of the file upload this necessarily pushed to a
lock starvation on the folder. Indeed you could end up with N jobs
asking for the lock at the same time. So just avoid parallelizing for
now even though it will be slow.
We could try to optimize but that'd require some serious changes to the
sync logic on the jobs... let's stabilize first and optimize later.

In such cases we get a download for which _file is already the demangled

This means adjusting PropagateDownloadEncrypted so that it knows where
the file will end (otherwise it would create temporary files in non
existant paths for instance).
In turn we have to adjust PropagateDownloadFile accordingly so that it
resolves the local folder the file will end up in.
And last we adjust PropagateLocalMkdir to resolve paths as well and
demangle as needed.

We ensure the PROPFIND Depth is infinity by explicitly specifying the
header (turns out our implementation just doesn't assume infinity
otherwise). This way we have a clear picture about *all* the folders of
the user, otherwise ClientSideEncryption couldn't be a trustable oracle
on the encryption state for any folder not on the root and all the
encryption code assumes it has a full picture of encryption.

We catch when a directory is inside a known encrypted folder and in such
a case we now do the following:
1) we encrypt the folder meta data (its name) properly and create it
under that mangled name on the server side
2) we mark the new folder itself as encrypted

This is a much better place than the GUI, this way we ensure the
propagator is always operating of up to date information. Previously if
the propagator kicked in without user interaction from startup (not
showing the settings dialog) it would have no E2E information available
whatsoever... unsurprisingly it would thus take wrong information at
every turn.

Due to usage of early-returns, combined with malloc/free,
several buffers that get allocated are leaked when an error
occurs.
Several functions had potential leaks:
- `encryptStringSymmetric` leaked `ctext`
- `EncryptionHelper::fileDecryption` leaked `out`
- `EncryptionHelper::fileEncryption` leaked `out`
Most of the functions had leaks of the cypher context.
This patch uses `QByteArray` as the handler for the dynamically
allocated buffers for openssl to operate on. This also removes
the need for conversions from malloc'd buffers to `QByteArray`
variables previously present in the code.
It also introduces a `CypherCtx` thin wrapper class to provide
a leak-free handling of `EVP_CIPHER_CTX`.
In owncloudsetupnocredspage.ui, the URL input field leUrl has a
placeholder text saying "https://..." which is a very useful hint
for the user. However, in the OwncloudSetupPage constructor, the
placeholer text is overwritten by the return string of the theme's
wizardUrlHint() method. The NextcloudTheme class does not override
this virtual method, so an empty string is used.
To make available the "https://..." hint, it is moved from the
UI file to NextcloudTheme::wizardUrlHint(). Note that, if a
theme is used which does not allow a custom server URL, the
placeholder text is now empty. This makes sense because the
input field is disabled in that case.
