The E2E application allows creating unencrypted subdirectories
in an encrypted parent. This is a big privacy problem.
This patch shows a red broken lock icon for these subdirectories
in the NC client UI.

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`.
- Text changed to "Enable..." instead of "Setup"
- The close icon follows NC style
- "end-to-end" instead of "end to end"

Instead of immediately popping up the mnemonic dialogue,
only show a notification bar on the account setup page.
For the cases where the user does not want to use E2E,
this is significantly less intrusive than the old approach.
The quota retrieval process might not be finished by the time
the used space on the server (`_rSize`) is compared against
the locally available disk space which might end up in
a "There isn't enough free space in the local folder!" message
even if there is enough free space.
This patch updates the status after the quota has been retrieved.
It also initializes `_rSize` to `-1` so that errors like this
are easier to catch in the future.
