From: Jiang Xin <worldhello.net@gmail.com>
Johannes found a flaky hang in `t5411/test-0013-bad-protocol.sh` in the osx-clang job of the CI/PR builds, and ran into an issue when using the `--stress` option with the following error messages:
fatal: unable to write flush packet: Broken pipe
send-pack: unexpected disconnect while reading sideband packet
fatal: the remote end hung up unexpectedlyIn this test case, the "proc-receive" hook sends an error message and dies earlier. While "receive-pack" on the other side of the pipe should forward the error message of the "proc-receive" hook to the client side, but it fails to do so. This is because "receive-pack" uses `packet_write_fmt()` and `packet_flush()` to write pkt-line message to "proc-receive" hook, and these functions die immediately when pipe is broken. Using "gently" forms for these functions will get more predicable output.
Add more "--die-*" options to test helper to test different stages of the protocol between "receive-pack" and "proc-receive" hook.
