Fix a number of smaller issues surrounding ErrorLogTimeout, some of which I introduced with https://bugs.openjdk.org/browse/JDK-8303861:
- Make ErrorLogTimeout an `unsigned`. Its "number of seconds", and unsigned gives us 130+ years, which is enough for the error log timeout. - Clarified the special value "0" to mean "no error log timeout" - renamed TIMESTAMP_TO_SECONDS_FACTOR to the less confusing SECONDS_TO_NANOS_FACTOR, and removed the useless `VMError::get_current_timestamp()` wrapper. - Fixed the calculation of error step timeouts to actually use a 5-second cap as intended, and clarified the comment. - Test changes: Some tests relied on ErrorLogTimeout to be a uint64_t. Replaced those with a different parameter that still is. --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - fix macos build error - start Changes: https://git.openjdk.org/jdk/pull/32510/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=32510&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8379453 Stats: 32 lines in 5 files changed: 3 ins; 9 del; 20 mod Patch: https://git.openjdk.org/jdk/pull/32510.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/32510/head:pull/32510 PR: https://git.openjdk.org/jdk/pull/32510
