cc84460c164bcb2a874d4f08b3a2624e5ee9ff0a test: move sync_blocks and sync_mempool functions to test_framework.py (Roy Shao) Pull request description: This PR moves `sync_blocks` and `sync_mempool` out from `test_framework/util.py` to `test_framework/test_framework.py` so they can take contextual information of test framework into account. * Change all reference callers to call functions from `test_framework.py` * Remove `**kwargs` which is not used * Take into account of `timeout_factor` when respecting timeout in function implementations. * Pass all tests by running `./test/functional/test_runner.py` fixes #18930 ACKs for top commit: MarcoFalke: ACK cc84460c164bcb2a874d4f08b3a2624e5ee9ff0a , reviewed with --color-moved=dimmed-zebra --color-moved-ws=ignore-all-space 💫 Tree-SHA512: a79b2a3fa842fc26a7aacb834bb2aea88b3049916c0b754e60002a77ce94bb5954e0ea3b436bf268e9295efb62d721dfef263a09339a55c684ac3fda388c275e
