Allow upgrade path when the server removes support for oauth

We also need to force the account to commit the config to the disk,
otherwise we may not register we are no longer using owncloud and we
risk sending the password as the token to the token refresh API call
Before commit d3b00532b1,
fetchFromKeychain was called everytime we detect that the creds are
invalid (in AccountState::slotInvalidCredentials)
But since that commit, AccountState was calling askFromUser directly,
breaking the refresh of the token.
So I made sure AccountState::slotInvalidCredentials still calls
refreshAccessToken.
Another change that was made was too be sure to clear the cookies
in HttpCredentials::invalidateToken even when we are only clearing the
access_token. That's because the session with a cookie may stay valid
longer than the access_token
We only want to know if they were touched within the last 15 seconds,
so change the data structure to use a QMultiMap, and sort them by
QElapsedTimer. This allows us to iterate over old entries ordered by
time and to stop once we find a recent entry.
This makes the look-up slower but in most cases the folder watcher
will report any change within milliseconds, and we start from the
most recent. What this really makes slower are actual user file
changes while a fast sync is underways which will need to iterate
over the whole map to find out the file isn't there.
This reduces the growth of the memory usage when downloading a large
amount of files.
We need Qt 5.9 for HTTP2 because, even if Qt 5.8 already has support
for it, there is some critical bug in the HTTP2 implementation which
make it unusable [ https://codereview.qt-project.org/186050 and
https://codereview.qt-project.org/186066 ]
When using HTTP2, we can use many more parallel network request, this
is especially good for small file handling
Lower the priority of the GET and PUT propagation jobs, so the quota
or selective sync ui PROPFIND will not be blocked by them
Since the user is already in the browser, put the error message in the
browser with a message to log out and then log in as the right user.
Issue #5895
Issues:
- #5661 On mac, iconv did not support all of unicode and some
files with emoji in the filename could not be uploaded
- #5719 , #5676 On linux, we will now support non utf-8 locale
Since these errors are blacklisted, it can take up to 24h to retry items
that had a 507 error for a while. This way users can intervene and cause
an upload attempt immediately.
It now produces a summary error message indicating the problem.
Adjust blacklist database table to contain 'errorCategory'. This is
useful for two things:
- Reestablishing summary messages based on blacklisted errors. For
example if we don't retry a 507ed file, we still want to show the
message about space on the server
- Selectively wiping the blacklist: When we have ui for something like
"I deleted some files, please retry all files now!", we want to
delete all blacklist entries of a specific category only.
* A bunch of code was determining sync status by ad-hoc comparing some
progress info fields. It can now just check the status, making it
easier to comprehend.
* There's a clear indication for "a new sync is starting", which helps
wiping the issues tab at the right time.
For now we use them for:
* csync errors: This allows them to appear in the sync issues tab
* insufficient local disk space, as a summary of individual file errors
Insufficient remote space will use them too, as might other issues that
are bigger than a single sync item.

This commit moves the reply after we got the token reply from
the server, that allows to reply with an error to the browser
if the login does not work.
