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.

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:
https://www.intel.com/content/www/us/en/developer/articles/technical/overview-of-intel-protected-file-system-library-using-software-guard-extensions.html
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

Suppress hadolint warnings for pinning version.
This is because these warnings are for reproducible builds.
But for development and CIs, ordinary case developers have to use the latest packages.
Memory num_bytes_per_page was incorrectly set in memory enlarging for
shared memory, we fix it. And don't set memory_data_size again for shared
memory.

Fix two issues of building WAMR on Windows:
- The build_llvm.py script calls itself, spawning instances faster than they expire,
which makes Python3 eat up the entire RAM in a pretty short time.
- The MSVC compiler doesn't support preprocessor statements inside macro expressions.
Two places inside bh_assert() were found.
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.
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.
Remove handling opcode DROP_64/SELECT_64 in loader stage
prepare_bytecode, as they are the modified opcodes of DROP/SELECT
for optimization purpose, but not the opcodes defined by spec.
Add more checks for Fast JIT to fix the issues reported by instrument test:
- add check for the jit_value before pushing it into the stack
- add check at the end of form_and_translate_func
- add checks after each jit pass
