Avoid the stack traces getting mixed up together when multi-threading is enabled by using exception_lock/unlock in dumping the call stacks. And remove duplicated call stack dump in wasm_application.c. Also update coding guideline CI to fix the clang-format-12 not found issue.
When destroying wasi-nn context, module instance should be also removed from hashmap to avoid memory leak.
Fixed a bug in the processing of the br_table_cache opcode that caused out-of-range references when the label index was greater than the length of the label.
To make it clearer to users when synchronization behaviour is not supported, return ENOTSUP when O_RSYNC, O_DSYNC or O_SYNC are respectively not defined. Linux also doesn't support O_RSYNC despite the O_RSYNC flag being defined.
This PR adds the Cosmopolitan Libc platform enabling compatibility with multiple x86_64 operating systems with the same binary. The platform is similar to the Linux platform, but for now only x86_64 with interpreter modes are supported. The only major change to the core is `posix.c/convert_errno()` was rewritten to use a switch statement. With Cosmopolitan errno values depend on the currently running operating system, and so they are non-constant and cannot be used in array designators. However, the `cosmocc` compiler allows non-constant case labels in switch statements, enabling the new version. And updated wamr-test-suites script to add `-j <platform>` option. The spec tests can be ran via `CC=cosmocc ./test_wamr.sh -j cosmopolitan -t classic-interp` or `CC=cosmocc ./test_wamr.sh -j cosmopolitan -t fast-interp`.
