Upgrade to 1.55 nightly

[celaus]

Hi! We needed to use a compiler > 1.50 for adding new dependencies that rely on const generics. Since std::raw has been removed in current nightly versions (and it's not entirely clear to me where it's used in the SGX SDK) this compiler upgrade should be safe to make. All the sample code compiles and I could manually run several of them inside the 18.04 container.

For anyone also using 3rd party ports of libraries to this SGX SDK (because they won't build with the new compiler version out of the box), use this in your Cargo.toml (upgrade later to this - official - repo):

Don't forget to cargo update

Somewhat fixes #315

@volcano0dr @dingelish Any chance to merge this?

[volcano0dr]

@celaus @xu-cheng I plan to upgrade the rust toolchain on the v1.1.4-testing branch soon.

[xu-cheng]

Hi, sorry to ping again. But any chance to move this forward?

Noted that Rust 2021 edition is about to be stabilize in Rust 1.56, which will be in beta in a week. We should really upgrade the support rust version of this SDK. Otherwise, it is likely that many crates will stop compiling if they are upgrading to 2021 edition.

I think this should be properly resolved as soon as possible.

@volcano0dr any timeline for the new version?

[PiDelport]

The v1.1.4-testing branch was merged, with toolchain nightly-2021-09-13 (rustc 1.57.0-nightly).
