JiDe Zhang 6745b7bd49 selection: allows using a wrapper source to filter data
1. Added support for intercepting clipboard selection operations.
2. Wraps data sources to control data provision based on client PID.
3. Added wlr_data_receiver to data source's send to identify the
recipient.
4. Includes new example "clipboard-control.c" to illustrate clipboard
permission management.
5. Added PID and client members to data source and receiver for access
control.
