build problem

[my-vegetable-has-exploded]

rdma-sys build fail with new clang version.

  --- stderr
  thread 'main' panicked at '"ib_uverbs_flow_action_esp_encap_union_(anonymous_at_/usr/include/infiniband/ib_user_ioctl_verbs_h_189_2)" is not a valid Ident', /home/wy/.cargo/registry/src/index.crates.io-6f17d22bba15001f/proc-macro2-1.0.60/src/fallback.rs:791:9

It seem that llvm changes cause this problem according to bindgen issue 2312.

If change bindgen to "0.66.1", async-rdma will build fail with ibv_access_flags and ibv_event_type doesn't implement Debug because of derive_debug(false) build.rs#L145

`ibv_event_type` doesn't implement `Debug`
the trait `Debug` is not implemented for `ibv_event_type`
the trait `Debug` is implemented for `Arc<T>`

And if change build.rs#L145 to derive_debug(true), rdma-sys will build fail with following error.

`libc::pthread_mutex_t` doesn't implement `Debug`
the trait `Debug` is not implemented for `libc::pthread_mutex_t`

My solution is to add some no_debug

.derive_debug(true)
.no_debug("ibv_qp")
.no_debug("ibv_context")
.no_debug("ibv_cq_ex")
.no_debug("ibv_srq")
.no_debug("ibv_wq")
.no_debug("ibv_cq")

Hi, @my-vegetable-has-exploded
I found that the ibv_event_type and ibv_access_flags build by the 0.59 bindgen have implemented Debug even if the .derive_debug(false).
And the the newer bindgen doesn't impl that, so you made this change?

yes, I also feel confused about why they still implement Debug in 0.59.😂
