Summary:
This patch adds a timeout of 500ms to death tests. As we add multithreaded code and locks, deadlocks become more likely so timeout will be useful.
Additionally:
- Better error handling in `invokeSubprocess`
- Makes `ProcessStatus`'s methods const

Summary: This patch adds `EXPECT_EXITS` and `EXPECT_DEATH` macros for testing exit codes and deadly signals. They are less convoluted than their analogs in GTEST and don't have matchers but just take an int for either the exit code or the signal respectively. Nor do they have any regex match against the stdout/stderr of the child process.
