This PR adds the OP-TEE adaptation patches for Rust 1.99.0 and libc 0.2.189,
enabling Rust standard library support for OP-TEE Trusted Applications.
Compared with the previous port:
- `library/std/src/thread/lifecycle.rs` no longer needs to be patched. The
AArch64 OP-TEE target specification has been fixed to set `singlethread: true`,
allowing the standard library to
select its single-threaded implementation. As a result, the multi-threaded
lifecycle code is not compiled for this target.
- The C function declarations in `libc/src/optee/mod.rs` have been
reordered to follow the order of the corresponding OP-TEE header files. This is
an organizational change and does not
alter their signatures or behavior.
- `library/std/src/sys/alloc/optee.rs` has been adapted to the latest Rust
standard library allocator interface. Instead of implementing `GlobalAlloc` for
`System`, the OP-TEE backend now
provides the allocator functions expected by `sys::alloc` and uses
`realloc_fallback` when the requested alignment cannot be handled directly by
`libc::realloc`.
