Refer to https://github.com/WebAssembly/WASI/blob/main/design/application-abi.md
to check the WASI ABI compatibility:
- Command (main module) may export _start function with signature "()"
- Reactor (sub module) may export _initialize function with signature "()"
- _start and _initialize can not be exported at the same time
- Reactor cannot export _start function
- Command and Reactor must export memory
And
- Rename module->is_wasi_module to module->import_wasi_api
- Refactor wasm_loader_find_export()
- Remove MULTI_MODULE related codes from mini_loader
- Update multi-module samples
- Fix a "use-after-free" issue. Since we reuse the memory instance of sub module,
just to protect it from freeing an imported memory instance
- move the wait_cond from exec_env to debug_instance, so the debug thread can be waken up by any threads
- process more general query message from debugger
- refine debug instance create/destroy mechanism
- avoid creating debug instance during module instantiating
- avoid blocking execution thread during creating debug instance
- update related documents
Don't throw exception when module_malloc memory failed:
- Exception will terminate the wasm app, it's not necessary since app can
check the result of dynamic allocation and do some cleanup or fallback
operation on failure instead of 'crash' directly.
- In acquire_wait_info, call hasn_map_find only when the address isn't NULL,
or there are many senseless error logs
Fix some potential pointer overflows in aot applying relocations and
several other places.
And add sanitizer compiler flags to wamrc CMakeLists.txt to detect
such issues.
Implement source debugging feature for classic interpreter and AOT:
- use `cmake -DWAMR_BUILD_DEBUG_INTERP=1` to enable interpreter debugging
- use `cmake -DWAMR_BUILD_DEBUG_AOT=1` to enable AOT debugging
See doc/source_debugging.md for more details.
Implement wasm_runtime_init_thread_env() for Windows platform by calling os_thread_env_init(): if current thread is created by developer himself but not runtime, developer should call wasm_runtime_init_thread_env() to init the thread environment before calling wasm function, and call wasm_runtime_destroy_thread_env() before thread exits.
And clear compile warnings for Windows platform, fix compile error for AliOS-Things platform

Remove check for heap_size==0 when creating wasi ctx, as the related data structures are allocated from global heap instead of app heap now, so it also works when app heap isn't created.
Also add v128 type for Windows so as to fix wamrc compilation error in Windows platform.

And add native symbol node to list head when registering native symbol, so as to lookup developer's registered node firstly when linking.

In some platforms, allocating memory with size 0 may return NULL but not an empty memory block, which causes runtime load, instantiate or execute wasm/aot file failed. We add checks to try to avoid allocating memory in runtime if the size is 0. And in wasm_runtime_malloc/free, output warning if allocate memory with size 0 and free memory with NULL ptr.
Also fix some coding style issues, fix handle riscv32 ilp32d issue, and fix several wasm-c-api issues.

And remove redundant FAST_INTERP macros in wasm_interp_fast.c, and fix wamrc --help wrong line order issue.

Re-implement aot call_indirect opcode translation: when calling non-import function, translate it by LLVM call IR to call the function in AOTed code, so as to avoid calling runtime aot_call_indirect API which is much slower. For import function, keep calling aot_call_indirect API due to the possible pointer/string argument conversion.
And add prompt info while app heap is corrupted, change emit_leb to emit_uint32 inter fast-interp to refine footprint.
