declare EnvKey before use to fix build error

Intrinsics can only be defined by the compiler.

@alexcrichton

use randSecure and randABytes r? @alexcrichton cc @n-salim

Fast path for vec.clear/truncate For trivial types like `u8`, `vec.truncate()`/`vec.clear()` relies on the optimizer to remove the loop. This means more work in debug builds, and more work for the optimizer. Avoiding this busywork is exactly what `mem::needs_drop::<T>()` is for.

Add long error explanation for E0493 Part of rust-lang#61137.

Fix inconsistent link formatting.

Trim rustc-workspace-hack Those dependencies seem no longer necessary. `./x.py test` and `x86_64-gnu-tools` container passed locally so I think this won't hurt.
