Add thread_wait_list_end node for thread data and cond for Windows platform
to speedup the thread join and cond wait operations: no need to traverse the
wait list to get the end node to append the wait node.
A limitation of the current implementation of SGX IPFS in WAMR is that
it prevents to open files which are not in the current directory.
This restriction is lifted and can now open files in paths, similarly to the
WASI openat call, which takes into account the sandbox of the file system.
Add a new options to control the native stack hw bound check feature:
- Besides the original option `cmake -DWAMR_DISABLE_HW_BOUND_CHECK=1/0`,
add a new option `cmake -DWAMR_DISABLE_STACK_HW_BOUND_CHECK=1/0`
- When the linear memory hw bound check is disabled, the stack hw bound check
will be disabled automatically, no matter what the input option is
- When the linear memory hw bound check is enabled, the stack hw bound check
is enabled/disabled according to the value of input option
- Besides the original option `--bounds-checks=1/0`, add a new option
`--stack-bounds-checks=1/0` for wamrc

Support to get/set recv_buf_size/send_buf_size/reuse_port/reuse_addr for wasm app
Add socket APIs for esp-idf platform
Add setsockopt for linux-sgx platform
Add macro WASM_ENABLE_WORD_ALING_READ to enable reading
1/2/4 and n bytes data from vram buffer, which requires 4-byte addr
alignment reading.
Eliminate XIP AOT relocations related to the below ones:
i32_div_u, f32_min, f32_max, f32_ceil, f32_floor, f32_trunc, f32_rint
The host embedder may new/delete wasm-c-api engine simultaneously
in multiple threads, which requires lock for the operations. Since there
isn't one time called global init/destroy APIs provided by wasm-c-api,
we define a global lock and initialize it with thread mutex initializer if
the platform supports that, and use it to lock the operations of engine.
If the platform doesn't support thread mutex initializer, we require
developer to create the lock by himself to ensure the thread-safe of the
engine operations.
With hardware boundary checking enabled, the app heap memory comes from `os_mmap()`.
Clearing the whole heap in the memory allocator causes process RSS to reach maximum
app heap size immediately and wastes lots of memory, so we had better remove the
unnecessary memory clean operations in the memory allocator.
1. Support cross building wamrc and installing it
2. Remove PIE flag for Windows to fix compilation error when compiled by clang
3. Support linking LLVM shared libs to help build with system default or custom
LLVM installation and reduce binary size.
This PR integrates an Intel SGX feature called Intel Protection File System Library (IPFS)
into the runtime to create, operate and delete files inside the enclave, while guaranteeing
the confidentiality and integrity of the data persisted. IPFS can be referred to here:

Introduce a cmake variable `WAMR_BUILD_SGX_IPFS`, when enabled, the files interaction
API of WASI will leverage IPFS, instead of the regular POSIX OCALLs. The implementation
has been written with light changes to sgx platform layer, so all the security aspects
WAMR relies on are conserved.
In addition to this integration, the following changes have been made:
- The CI workflow has been adapted to test the compilation of the runtime and sample
with the flag `WAMR_BUILD_SGX_IPFS` set to true
- Introduction of a new sample that demonstrates the interaction of the files (called `file`),
- Documentation of this new feature
Fix the issue reported by #1484:
Platform ESP-IDF broken for WAMR 1.0.0 with ESP-IDF 4.4.2
Let the dummy ftruncate only work with ESP-IDF earlier than 4.4.2
Implement more socket APIs, refer to #1336 and below PRs:
- Implement wasi_addr_resolve function (#1319)
- Fix socket-api byte order issue when host/network order are the same (#1327)
- Enhance sock_addr_local syscall (#1320)
- Implement sock_addr_remote syscall (#1360)
- Add support for IPv6 in WAMR (#1411)
- Implement ns lookup allowlist (#1420)
- Implement sock_send_to and sock_recv_from system calls (#1457)
- Added http downloader and multicast socket options (#1467)
- Fix `bind()` calls to receive the correct size of `sockaddr` structure (#1490)
- Assert on correct parameters (#1505)
- Copy only received bytes from socket recv buffer into the app buffer (#1497)

And enable classic interpreter instead fast interpreter when llvm jit is enabled,
so as to fix the issue that llvm jit cannot handle opcode drop_64/select_64.
esp-idf: Make esp-idf support Libc WASI
1. Support to get WASM APP libs' DIR from upper layer
2. Add SSP support for esp-idf platform
3. Change the errno of readlinkat
Thread data should not be destroyed when thread exits, or other thread
may not be able to join it. This PR saves the thread data into thread data
list when thread exits, sets thread status and stores the return value, so
that other thread can join it.
Also set MEM_TOP_DOWN flag for Windows VirtualAlloc to yield LLVM
JIT relocation error.
And set opt/size level to 3 for LLVM JIT for future use, currently the flags
are not used by LLVM JIT.
Enhance the hw bound check reported in #1262:
When registering signal handlers for SIGSEGV & SIGBUS in boundary
check with hardware trap, preserve the previous handlers for signal
SIGSEGV and SIGBUS, and forward the signal to the preserved signal
handlers if it isn't handled by hw bound check.
Implement Go binding APIs of runtime, module and instance
Add sample, build scripts and update the document
