Since the Tensorflow library is already installed in many cases(especially in the
case of the embedded system), move the installation code to find_package.
According to the 1999 ISO C standard (C99), size_t is an unsigned integer type of
at least 16 bit (see sections 7.17 and 7.18.3), it may be uint32 in 32-bit platforms:

Calling function `size_t min(size_t, size_t)` with two uint64 arguments may get
invalid result.

Make `hmu_tree_node` struct packed and add 4 padding bytes before `kfc_tree_root_buf`
field in `gc_heap_struct` struct to ensure the `left/right/parent` fields in `hmu_tree_node`
are 8-byte aligned on the 64-bit target which doesn't support unaligned memory access.
Fix the issue reported in #2136.
This should allow users to use the vscode extension on ubuntu 20.04.
After https://github.com/bytecodealliance/wasm-micro-runtime/pull/2132 ,
our lldb binary for 20.04 works on ubuntu 22.04 as well.
On the other hand, lldb for 22.04 has no chance to work on ubuntu 20.04.
(because of glibc version requirement.)
- Translate all the opcodes of threads spec proposal for Fast JIT
- Add the atomic flag for Fast JIT load/store IRs to support atomic load/store
- Add new atomic related Fast JIT IRs and translate them in the codegen
- Add suspend_flags check in branch opcodes and before/after call function
- Modify CI to enable Fast JIT multi-threading test

Notably, this disables python scripting support on ubuntu:
* It isn't necessary for the primary purpose of this build. (that is, the vscode extension)
* It has been disabled in the macOS counterpart.
* It allows to use the same binary for 22.04 and 20.04. (note: 22.04 and 20.04 provide different versions of libpython)
In LLVM AOT/JIT compiler, only need to check the suspend_flags when memory is
a shared memory since the shared memory must be enabled for multi-threading,
so as not to impact the performance in non-multi-threading memory mode. Also
refine the LLVM IRs to check the suspend_flags.
And fix an issue of multi-tier jit for multi-threading, the instance of the child thread
should be removed from the instance list before it is de-instantiated.
In #1928 we added support for GCC 4.8 but we don't continuously test if it's
working. This PR added a GitHub actions job to test compilation on GCC 4.8
for interpreters and Fast JIT (LLVM JIT/AOT might be added in the future).
The compilation is done using ubuntu 14.04 image as that's the simplest way
to get GCC 4.8 compiler. The job only compiles the code but does not run any
tests.
Load memory data size in each time memory access boundary check in
multi-threading mode since it may be changed by other threads when
memory growing.
And use `memory->memory_data_size` instead of
`memory->num_bytes_per_page * memory->cur_page_count` to refine
the code.
When ref.func opcode refers to a function whose function index no smaller than
current function, the destination func should be forward-declared: it is declared
in the table element segments, or is declared in the export list.
In multi-threading, this line will eventually call `wasm_cluster_wait_for_all_except_self`:
`DEINIT_VEC(store->instances, wasm_instance_vec_delete)`
As the threads are joining they can call `wasm_interp_dump_call_stack` which tries to
use the module frames but they were already freed by this line:
`DEINIT_VEC(store->modules, wasm_module_vec_delete)`
This PR swaps the order that these are deleted so module is deleted after the instances.

Try using existing exec_env to execute wasm app's malloc/free func and
execute post instantiation functions. Create a new exec_env only when
no existing exec_env was found.
In some cases, the memory address of some variables may have 4 least significant
bytes set to zero. Because we cast the pointer to int, we look only at 4 least
significant bytes; the assertion may fail because 4 least significant bytes are 0.
Change bh_assert implementation to cast the assert expr to int64_t and it works
well with 64-bit architectures.
Update wasi-libc version to resolve the hang issue when running wasi-threads cases.
Implement custom sync primitives as a counterpart of `pthread_barrier_wait` to
attempt to replace pthread sync primitives since they seem to cause data races
when running with the thread sanitizer.
Remove the test in the sample of file interaction that tries to extend the file
at the end, because this is not supported by the specifications of fseek.
The WASI exit code is now propagated by the runtime, so the CI will
indicate when a test is failing.
