Fine grained filesystem setup

[icewind1991]

• Unify/cleanup filesystem setup Unify/cleanup filesystem setup #31431
  • Move root mount setup to mountprovider move root mount setup to mountproviders #31266
  • Move fs setup/teardown handling to it's own class
  • Call new fs setup from all the old places to remain compatible
• Cache mountprovider for each mount for user Add source mount provider to the oc_mounts table #30978
• Setup only mounts from relevant mount providers when accessing the filesystem
• Check places that setup the filesystem explicitly
• Ensure cached mounts get updated when needed

Instead of always setting up the entire filesystem, it tries to only setup the bits needed for the path being accessed.

this is done by looking at the cached mounts in the oc_mounts table to find the one matching for the path (and optionally also any mounts in subfolders), getting the mountpoints from these mounts and only setting up the mounts from those providers.

Various systems are in place to try and ensure that this doesn't lead to an outdated setup if the mounts accessible to the user has changed

• The setup logic listens to various core events that might cause mount changes (sharing, group membership changes, etc) and performs a full setup afterwards
• A new event has been added that apps can use to trigger a full setup the next time for cases not covered by the above events
• every 5min a full setup is trigger to ensure that even if something is missed the information isn't outdated for long

Ok, I think this is done for review/testing

Particular attention should be given to situations that change what mounts are available for a user (adding/removing shares/external storages/etc) and making sure file listings reflect these changes

@icewind1991 phpcs unhappy, can you fix ?

[blizzz]

also s3 tests don't pass

[PVince81]

all necessary tests passed successfully in previous builds and my recent changes are not related to those

the last commit was to satisfy "checkers" and that one passes now

merging...
