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
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
pool: 8.8.8.8/24 the application had access to the 127.0.0.1 address (which
should not).
Fix the following warning introduced by the recent change.

Re-implement socket api send/recv in an atomic-like way, fix the return value
check in posix.c.
And fix wasm-c-api sample callback_chain calling malloc issue.
wasm_c_api.c: add more checks, fix LOG_WARNING invalid specifier
aot_emit_aot_file: fix strncpy max size length to copy
posix.c: fix potential socket not close issue
wasm-c-api samples: add return value checks for fseek/ftell
cJSON.c: remove dead code
Fix wasm_application_execute_main/wasm_application_execute_func not waiting for
other threads to terminate in multi-thread mode, which causes that the exception
thrown by other threads may haven't been spreaded to current main thread, and
cannot be detected by the caller, as reported in #1131.
Add aot relocation for ".rodata.str" symbol to support more cases
Fix some coding style issues
Fix aot block/value stack destroy issue
Refine classic/fast interpreter codes
Clear compile warning of libc_builtin_wrapper.c in 32-bit platform
Fix compile warnings in libc-wasi posix.c:
```
posix.c:880:41: warning: comparison of integers of different signs:
'unsigned long' and 'ssize_t' (aka 'long') [-Wsign-compare]
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
Implement pthread_cond_broadcast wrapper for lib-pthread
- support pthread_cond_broadcast wrapper for posix/linux-sgx/windows
- update document for building multi-thread wasm app with emcc
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.
Refine some codes in wasm loader
Add -Wshadow to gcc compile flags and fix some variable shadowed issues
Fix function parameter/return types not checked issue
Fix fast-interp loader reserve_block_ret() not handle V128 return type issue
Fix mini loader load_table_segment_section() failed issue
Add detailed comments for argc argument in wasm_runtime_call_wasm()
- 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
