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
name and _encryptedFileName has the mangled information. This is
different to what we encountered so far where initially _file was
mangled and _encryptedFileName was empty. Let's deal with that case
properly.

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

It was assuming we'd encrypt only files but directory names also need to
be encrypted. We just skip the writing to temp file part in that case.

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.

In case of denormalized paths in the dav href (presence of . or .. in
the path) simple string startsWith comparison wasn't enough to know if
said href ended up in the right namespace. That's why we're now using
QUrl (pretending local file since we don't have a full URL in the href)
to normalize the path before comparison.
This could happen with broken proxies for instance where we would
wrongly validate the dav information resulting in potentially surprising
syncing and name collisions.

The message handler globally installed by the logger silently drop
messages if the logger is not logging. On top of it, it doesn't log
debug messages by default.
Anything not logged is currently silently discarded. This can come as a
surprise to a developer trying to contribute for the first time and
adding some debug message for some reason.
We're thus trying to strike a middle ground which is that debug messages
get a regular output if the logger isn't interested in them.
