The current implementation of remote attestation does not take into
account the integrity of the wasm module. The SHA256 of the wasm
module has been put into user_data to generate the quote, and more
parameters are exposed for further verification.
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
Allow to wait for a new debugger connection once the previous one
is disconnected:
- when receiving a detach command
- when the client socket is closed (for example, lldb process is killed)
Refactor the layout of interpreter and AOT module instance:
- Unify the interp/AOT module instance, use the same WASMModuleInstance/
WASMMemoryInstance/WASMTableInstance data structures for both interpreter
and AOT
- Make the offset of most fields the same in module instance for both interpreter
and AOT, append memory instance structure, global data and table instances to
the end of module instance for interpreter mode (like AOT mode)
- For extra fields in WASM module instance, use WASMModuleInstanceExtra to
create a field `e` for interpreter
- Change the LLVM JIT module instance creating process, LLVM JIT uses the WASM
module and module instance same as interpreter/Fast-JIT mode. So that Fast JIT
and LLVM JIT can access the same data structures, and make it possible to
implement the Multi-tier JIT (tier-up from Fast JIT to LLVM JIT) in the future
- Unify some APIs: merge some APIs for module instance and memory instance's
related operations (only implement one copy)
Note that the AOT ABI is same, the AOT file format, AOT relocation types, how AOT
code accesses the AOT module instance and so on are kept unchanged.

Initial integration of WASI-NN based on #1225:
- Implement the library core/iwasm/libraries/wasi-nn
- Support TensorFlow, CPU, F32 at the first stage
- Add cmake variable `-DWAMR_BUILD_WASI_NN`
- Add test case based on Docker image and update document
Refer to #1573
Add a couple of socket examples that can be used with WAMR:
- The `timeout_client` and `timeout_server` examples demonstrate socket
send and receive timeouts using the socket options
- The `multicast_client` and `multicast_server` examples demonstrate receiving
multicast packets in WASM
And add several macro controls for `socket_opts` example.
While compiling the file wasi_socket_ext.c with pedantic options (typically
`-Wimplicit-int-conversion` and `-Wmissing-prototypes`), some warnings are raised.
This PR addresses those warnings by adding missing static statements before
functions and explicitly casting a narrowing conversion.
And fix the error handling after calling getpeername.
The function was introduced to WASI about half a year ago after it already
existed in WAMR.
It caused problems with compiling `wasi_socket_ext.c` with the wasi-sdk
that already had this hostcall exported (wasi-sdk >= 15).
The approach we take is the following:
- we update WASI interface to be compatible with the wasi_snapshot_preview1
- compilation with `wasi_socket_ext.c` supports both wasi_sdk >= 15 and wasi_sdk < 15
(although we intend to drop support for < 15 at one point of time)
- we override `accept()` from wasi-libc - we do that because `accept()` in `wasi-libc`
doesn't support returning address (as it doesn't have `getpeername()` implemented),
so `wasi_socket_ext.c` offers more functionality right now
Resolves#1167 and #1528.

If WASM app has called pthread_detach() to detach a thread, it will be detached again
when thread exits. Attempting to detach an already detached thread may result in crash
in musl-libc. This patch fixes it.
Some configurations (eg. esp32/nuttx) have limited space for BSS,
0x20000 byte buffer is huge on embedded systems, change to
allocate the buffer dynamically.
esp-idf: Make esp-idf support Libc WASI
1. Support to get WASM APP libs' DIR from upper layer

3. Change the errno of readlinkat
Remove some unused fields in module instance and the related codes,
which are introduced by emsdk some special mode (-DSIDE_MODULE=1),
and are not required now.
The existing validation didn't work as expected; e.g. for address

should not).
Fix the following warning introduced by the recent change.

if (bufoff + iov[i].buf_len < len) {
posix.c:1359:32: warning: comparison of integers of different signs:
'off_t' (aka 'long long') and 'unsigned long long' [-Wsign-compare]
if (ret == 0 && sb.st_size < offset + len)
```
The format specifiers of %ld/%lu/%li/%lx/%lp/%lo (or %z* and %t* like) should
be treated as 32-bit integer in wasm.
And merge the handle of unsigned/signed for %u/%d and %llu/%lld specifier
when calling snprintf.
During debugging, the debug client may request to malloc a memory space
to evaluate the user expressions. If we malloc memory from the linear memory,
it may fail when the thread is in stop status. We preserve a buffer during
creating debug instance, and use a simple bump pointer allocator to serve lldb's
memory request.
In thread_manager.c, `wasm_cluster_spawn_exec_env` creates a new module
instance but not sets wasi_ctx, so when the new exec_env calls wasm function
which uses WASI API, the WASI API functions in `libc_wasi_wrapper.c` will get
null result in calling `get_wasi_ctx` and then return `wasi_errno`.

Refer to [Networking API design](https://github.com/WebAssembly/WASI/issues/370)
and [feat(socket): berkeley socket API v2](https://github.com/WebAssembly/WASI/pull/459):
- Support the socket API of synchronous mode, including `socket/bind/listen/accept/send/recv/close/shutdown`,
the asynchronous mode isn't supported yet.
- Support adding `--addr-pool=<pool1,pool2,..>` argument for command line to identify the valid ip address range
- Add socket-api sample and update the document

Fix __wasi_subscription_t structure definition inconsistent with wasi-libc
definition issue, reported by #961, tested with sleep, poll API and other
wasi cases on x86-64, x86-32 and arm32 targets.
Fix the issue that joining a detached thread might result in joining hang,
resolve the issue by adding wait_count for a thread's exec_env to indicate
whether a thread needs to detach itself or not when it exits.
And add checks for the input exec_env for cluster's join/detach/cancel thread.
- use platform independent data types in debug-engine library
- add os_socket APIs and provide windows and posix implementation
- avoid using platform related header files in non-platform layer
- use format specifiers macros for sprintf and sscanf
- change thread handle type from uint64 to korp_tid
- add lock when sending socket packet to avoid thread racing
Use `PRIxxx` related macros to format the output strings so as to clear
compile warnings, e.g. PRIu32, PRId32, PRIX32, PRIX64 and so on.
And add the related macro definitions in platform_common.h if they
are not defined, as some compilers might not support them.

- 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
The debug_instance_list is not protected by mutex, and the debug instance uses
the length of this list as its id. If several threads create debug instance at the
same time, they may get duplicated/same ids. This patch adds mutex to protect
this list.
The destroy_callback_list variable in thread_manager_destroy is not cleared.
When wamr is started as a task, after exiting and restarting, it will loop
endlessly in traverse_list.

The last argument arg of pthread_create passed from wasm app is opaque
for the library and host, it should be returned back to the wasm app without
