One can access CurlRequest's NetworkReadStream in order to find out HTTP
response code or some other Stream-related data.
OneDriveTokenRefresher uses it to print some info on that 404 error I'm
trying to troubleshoot.
It reads the passed NetworkReadStream and prints its contents onto
console (for now). It would be writing contents into file.
To simplify work with raw NetworkReadStream there is a new CurlRequest.
It basically does nothing, but as ConnMan handles transfers only if
there is an active Request, you need some Request to get
NetworkReadStream working. Thus, there is a CurlRequest, which is active
until NetworkReadStream is completely read. CurlRequest also has useful
addHeader() and addPostField() methods in order to customize the request
easily. Use execute() method to get its NetworkReadStream.
DropboxStorage implements streamFile() and download() API methods. As
DownloadRequest is incomplete, it is not actually downloading a file,
though.
With ConnectionManager singleton one can start their Requests without
creating Storage instance. Moreover, Storage instance should contain
cloud API, not Requests-related handling and timer starting methods.
Thus, these methods were moved into ConnectionManager itself.
This commit adds:
* ConfMan's new "cloud" domain;
* CloudManager's init() method, where it loads keys from "cloud" configs
domain;
* CurlJsonRequest's addHeader() and addPostField() methods;
* temporary Storage's printInfo() method;
* DropboxStorage's implementation of printInfo(), which is using access
token and user id;
* DropboxStorage's loadFromConfig() static method to load access token
and user id from configs and create a Storage instance with those;
* temporary DropboxStorage's authThroughConsole() static method, which
guides user through auth process from the console.
So, in CloudManager's init() implementation ScummVM checks that there is
"current_storage_type" key in "cloud" domain of configs, and loads
corresponding storage if there is such key.
If there is no such key, ScummVM offers user to auth with Dropbox.
That's done through console, and thus it's temporary (it also requires
restarting ScummVM twice and manually editing config.ini file).
Now it is based on MemoryReadWriteStream, which is introduced by this
commit. This stream is using ring buffer and is dynamically increasing
its size when necessary.
