txg_wait_synced_sig() is "wait for txg, unless a signal arrives". We expect that future development will require similar "wait unless X" behaviour. This generalises the API as txg_wait_synced_flags(), where the provided flags describe the events that should cause the call to return. Instead of a boolean, the return is now an error code, which the caller can use to know which event caused the call to return. The existing call to txg_wait_synced_sig() is now txg_wait_synced_flags(TXG_WAIT_SIGNAL). Sponsored-by: Klara, Inc. Sponsored-by: Wasabi Technology, Inc.
