68400d8b96 tests: Use explicit imports (practicalswift) Pull request description: Enable automatic detection of undefined names in Python tests scripts. Remove wildcard imports. Wildcard imports make it unclear which names are present in the namespace, confusing both readers and many automated tools. An additional benefit of not using wildcard imports in tests scripts is that readers of a test script then can infer the rough testing scope just by looking at the imports. Before this commit: ``` $ contrib/devtools/lint-python.sh | head -10 ./test/functional/feature_rbf.py:8:1: F403 'from test_framework.util import *' used; unable to detect undefined names ./test/functional/feature_rbf.py:9:1: F403 'from test_framework.script import *' used; unable to detect undefined names ./test/functional/feature_rbf.py:10:1: F403 'from test_framework.mininode import *' used; unable to detect undefined names ./test/functional/feature_rbf.py:15:12: F405 bytes_to_hex_str may be undefined, or defined from star imports: test_framework.mininode, test_framework.script, test_framework.util ./test/functional/feature_rbf.py:17:58: F405 CScript may be undefined, or defined from star imports: test_framework.mininode, test_framework.script, test_framework.util ./test/functional/feature_rbf.py:25:13: F405 COIN may be undefined, or defined from star imports: test_framework.mininode, test_framework.script, test_framework.util ./test/functional/feature_rbf.py:26:31: F405 satoshi_round may be undefined, or defined from star imports: test_framework.mininode, test_framework.script, test_framework.util ./test/functional/feature_rbf.py:26:60: F405 COIN may be undefined, or defined from star imports: test_framework.mininode, test_framework.script, test_framework.util ./test/functional/feature_rbf.py:30:41: F405 satoshi_round may be undefined, or defined from star imports: test_framework.mininode, test_framework.script, test_framework.util ./test/functional/feature_rbf.py:30:68: F405 COIN may be undefined, or defined from star imports: test_framework.mininode, test_framework.script, test_framework.util $ ``` After this commit: ``` $ contrib/devtools/lint-python.sh | head -10 $ ``` Tree-SHA512: 3f826d39cffb6438388e5efcb20a9622ff8238247e882d68f7b38609877421b2a8e10e9229575f8eb6a8fa42dec4256986692e92922c86171f750a0e887438d9
