This changes the names to match what cbindgen wants to call these when we migrate this enum to Rust. (I tried instead adding cbindgen annotations to a Rust version of the enum, but it doesn't seem to work).
Notably this removes the user-facing experimental options `preload_spin_max` and `use_explicit_block_message`, and hard-wires the current defaults of not spinning and not using an explicit block message (which would be redundant with spinning disabled). We've stopped using these options, and I haven't bothered reimplementing them in the Rust version of `IPCData`.
We can use ShimEvent's discriminant directly instead of maintaining a mapping.

I think the improvement here is an illusion. It doesn't show up in microbenchmarks, and the current version of IPC using SelfContainedMutex now appears to have the same performance as the C version. https://github.com/shadow/benchmark-results/blob/master/tor/2023-03-16-T13-26-54/plots/run_time.png |
