We mostly trust the file watchers meaning that we don't re-scan the
local tree if we have done that recently and no file watcher events
have arrived. If the file watchers invalidate a subtree, we rescan
only that subtree.
Since we're not entirely sure the file watchers are reliable, we still
do full local discoveries regularly (1h by default). There is a config
file setting as well as an environment variable to control the interval.
Add state and signal to catch the following two known problems:
* Linux: inotify user watch pool is exhausted. Folder watcher becomes
unreliable.
* Windows: buffer is too small, some notifications are lost but watching
stays reliable.
This makes it unnecessary for FolderMan to manage the list and removes
the need for some forwarders.
This is done in preparation for follow-up commits that want to add
diagnostics to FolderWatcher that shall be available from within Folder.
Previously it could only display synchronization progress or "up to
date". Now it also communicates the same overall state that the icon
shows.

Comparison of file sizes for potential conflicts was added in
0eb9401c62, but did not extend to checking
the file size in case of potential local moves.
This commit adds this check and adds tests for various move+change
scenarios.
On Mac, this halves the time spent in csync_excluded_traversal
when using check_csync_excluded_performance. A similar performance
increase is seen on linux.
Make admin folder optional. It is needed for osx, but it is deleted from Linux builds for the sake of easier license review as discussed in https://github.com/owncloud/client/issues/6005
Fix performence regression from commit d66c2b5fae
For every new file we would look up every parent directories. Allocating
a new QByteArreay for every parent riectory just to know if it is in the other
tree is wasting lots of CPU.
Use a ByteArrayRef trick, similar to QStringRef
