By default QNetworkReply::errorString() often produces messages like
"Error downloading <url> - server replied: <reason>"
but the "downloading" part invariably confuses people since the
error might very well have been produced by a PUT request.
This commit produces clearer error messages for HTTP errors.
Additionally:
* Remove some unnecessary null checks from slots connected to
network job signals and document that these signals never send
null replies.
* There was a bug where AbstractNetworkJob::_timedout wasn't
set when derived classes overrode slotTimeout. We now ensure
it's always set by disallowing overrides of slotTimeout.
Instead it now calls onTimedOut, which allows custom handling.
* Several subclasses declared errorString, isTimedOut. Move
these to AbstractNetworkJob.
* Unify handling of OC-ErrorString (via the new, general
Job::errorString)
* Add documentation in various places.
* make target duration a client option instead of a capability
* simplify algorithm for determining chunk size significantly
* preserve chunk size for the whole propagation, not just per upload
* move options to SyncOptions to avoid depending on ConfigFile
in the propagator
* move chunk-size adjustment to after a chunk finishes, not when
a new chunk starts
Avoid using connections to report up the job tree for signals
that we can directly communicate to the OwncloudPropagator.
This slightly reduces the memory usage and avoid passing those calls
through the whole parent chain.

We do not track the success or error of the DeleteJob because it does not
matter. If it fails, it might be because the chunks were already removed.
If not, the chunks will be stale, but the server must anyway do a few
cleanup from time to time because we do not always remove the chunks
Previously this wasn't happening for errors that were not
NormalErrors because they don't end up in the blacklist.
This revises the resetting logic to be independent of the
error blacklist and make use of UploadInfo::errorCount
instead.
412 errors should reset chunked uploads because they might be
indicative of a checksum error.
Additionally, server bugs might require that additional
errors cause an upload reset. To allow that, a new capability
is added that can be used to advise the client about this.
This could make sure that the network job gets deleted if the parent job gets
deleted, and would avoid crashes like:

(#5329)
The rules to select the webdav url are now:
- If the server reports that the new chunking algorithm is working,
always use remote.php/dav/files/<username>
This capability can be overriden with an environment variable
- Otherwise, use the dav path provided by the theme, which defaults to
remote.php/webdav
This means that with the newer server, the branding can no longer override
the webdav URL. If there is still an usecase for the branding to do so, we
need to find another way to override it. But it is now more complicated to
configure as might need include the username and need different endpoint
depending on the operations (chunks or not)
Issue #4007
We are going to change the webdav path depending on the capabilities.
But the SyncEngine and csync might have been created before the capabilities
are retrieved.
The main raison why we gave the path to the sync engine was to pass it to csync.
But the thing is that csync don't need anymore this url as everything is done by the
discovery classes in libsync that use the network jobs that use the account for the urls.
So csync do not need the remote URI.
shortenFilename in folderstatusmodel.cpp was useless because the string is the
_file of a SyncFileItem which is the relative file name, that name never
starts with owncloud://.
All the csync test creates the folder because csync use to check if the folder
exists. But we don't need to do that anymore
These are not understood by owncloud yet, but were requested for CernBox
OC-Total-Length in the MKCOL: The full lenght of the file
OC-Chunk-Offset in the PUT: The offset within the file in which this chunk belongs
OC-Checksum in the MOVE: The transission checksum
