Remove the `const` flag for the first argument `buf` of wasm_runtime_load as
it might be modified by runtime for footprint and performance purpose, and
update the related functions and document.
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
Update CI files:
- add another apt repository for spec test on x86-32 as some packages
cannot be downloaded with the Github default repository
- trigger the CI file when it is modified
Fix several issues in wasm-c-api wasm_module_imports function:
1. Two of the if branches never set the module_name and name fields which are later passed as arguments to wasm_importtype_new, and eventually might cause double-free and/or use-after-free
2. Should zero module_name/name/extern_type at the start of loop iteration, and destroy their resources when failed at the end of loop iteration
2. No need to check `if (!extern_type) { continue; }`, as extern_type is converted from type and type is already checked
3. No need to wasm_importtype_vec_delete(out) when failed, as it is passed from outside and should be destroyed by outside
When calling native function from AOT code, current implementation is to return
back to runtime to call aot_invoke_native, which calls wasm_runtime_invoke_native
and the latter calls assembly code. We did it before as there may be pointer and
string arguments to check and convert if the native function's registered signature
has character '*' and '$'.
As the built-in native function's signatures can be gotten in compilation time, we
check the pointer/string arguments and convert them into native address in AOT
code, and then invoke the native function directly, so as to improve performance.
The littlevgl library had changed its name and domain to [LVGL](https://lvgl.io).
See https://blog.lvgl.io/2020-06-01/announcement
We change some names and links accordingly.
Also remove the cloning for tlsf library as it isn't used now.
Increase default/min native stack size when UVWASI is enabled as
UVWASI requires larger native stack size.
Increase the reserved bytes to the native thread stack boundary to
better detect the native stack overflow.
Set WASM_DISABLE_HW_BOUND_CHECK to 0 when interpreter is
enabled and AOT is disabled, as memory access boundary check
with hardware trap is only enabled in AOT/JIT mode.
Implement WAMR-IDE with vscode extension to enable developing
WebAssembly applications with coding, building, running and

Use LLVM new pass manager for wamrc to replace the legacy pass manger,
so as to gain better performance and reduce the compilation time.
Reference links:
- https://llvm.org/docs/NewPassManager.html
- https://blog.llvm.org/posts/2021-03-26-the-new-pass-manager
And add an option to use the legacy pm mode when building wamrc:
cmake .. -DWAMR_BUILD_LLVM_LEGACY_PM=1
For JIT mode, keep it unchanged as it only runs several function passes and
using new pass manager will increase the compilation time.
And refactor the codes of applying LLVM passes.
Refactor LLVM Orc JIT to actually enable the lazy compilation and speedup
the launching process:
https://llvm.org/docs/ORCv2.html#laziness
Main modifications:
- Create LLVM module for each wasm function, wrap it with thread safe module
so that the modules can be compiled parallelly
- Lookup function from aot module instance's func_ptrs but not directly call the
function to decouple the module relationship
- Compile the function when it is first called and hasn't been compiled
- Create threads to pre-compile the WASM functions parallelly when loading
- Set Lazy JIT as default, update document and build/test scripts
Currently when calling wasm_runtime_call_wasm() to invoke wasm function
with externref type argument from runtime embedder, developer needs to
use wasm_externref_obj2ref() to convert externref obj into an internal ref
index firstly, which is not convenient to developer.
To align with GC feature in which all the references passed to
wasm_runtime_call_wasm() can be object pointers directly, we change the
interface of wasm_runtime_call_wasm() to allow to pass object pointer
directly for the externref argument, and refactor the related codes, update
the related samples and the document.
Refine is_xip_file check, when e_type isn't E_TYPE_XIP, just return false
and no need to go through all the other sections of the AOT file.
Refine pointer range check, convert pointer to uintptr_t type before
comparison to yield possible sanitizer pointer overflow error.
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.
Put Vectorize passes before GVN/LICM passes as normally the former
gains more performance improvement and the latter might break the
optimizations for the former. Can improve performance of several
sightglass cases.
And don't check exception throw after calling an AOT function if it is
and recursive call, similar to handing of Spec tail call opcode.
Enable running XIP file on Windows platform.
And add more strict checks for wamrc to report error when the input file
is same with output file, or the input file is AOT file but not wasm file.
Fix some issues on MacOS platform
- Enable libc-wasi by default
- Set target abi to "gnu" if it is not set for wamrc to avoid generating
object file of unsupported Mach-O format
- Set `<vendor>-<sys>` info according to target abi for wamrc to support
generating AOT file for other OSs but not current host
- Set cpu name if arch/abi/cpu are not set to avoid checking SIMD
capability failed
- Set size level to 1 for MacOS/Windows platform to avoid relocation type
unsupported warning
- Clear posix_memmap.c compiling warning
- Fix spec case test script issues, enable test spec cases on MacOS

Fix the sensor framework timer issue reported by #884 when setting
`ms_to_next_check`, and unify the type of time related args/vars to
uint32 to avoid potential type conversion issues, and fix the compile
warnings.
And update the sensor sample by creating two sensors to confirm that
the fix works correctly.
Lookup float/double constants from exec_env->native_symbol table
but not construct them with LLVMBuildConst if XIP mode is enabled,
these constants are introduced by f32/f64.const opcodes and some
float/double conversion opcodes, and make wamrc generate some
relocations in text section of AOT XIP file. This patch eliminates such
relocations when "--enable-indirect-mode" is added to wamrc.
Use the previous resolved binary type info (obj_data->target_info.bin_type) to
check the endian and bit-width but not the raw binary info, the latter is not
suitable for the check for Win32 object file type.
And fix the symbol comparison issue in resolve_target_sym(), as in Win32, the
symbol name of a function added by LLVMAddFunction() is prefixed by '_',
which leads to invalid result returned by strcmp().
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

Auto detect whether file is XIP file before loading module in posix like and
linux-sgx platforms, and if yes, mmap executable memory automatically to
run the XIP file.
Add document about XIP feature.
Enable test spec cases with XIP feature.
When auxiliary stack global isn't found in wasm app, it must be unused in
the wasm app, we set it to __heap_base global and set its size to 0, so as to
shrink the linear memory to reduce the memory consumption.
Fix some potential pointer overflows in aot applying relocations and
several other places.
And add sanitizer compiler flags to wamrc CMakeLists.txt to detect
such issues.
Enable LLVM link time optimization for AOT and enable it by default,
and provide "wamrc --disable-llvm-lto" option to disable it.
And modify the spec test script, disable it by default when testing
spec cases.

Currently the string in the wasm/aot file will be duplicated and stored
into const string list/set in interpreter/aot loader, which leads to extra
unnecessary memory consumption if the file buffer can be referred to
after loading. We refine the string storage by:
- if the file buffer can be referred to after loading and it is writable, we
reuse the file buffer to store the string but not store it into the const
string set: move string backward and append '\0'
- emit string with '\0' only for XIP mode in which the AOT file is readonly
- if the file buffer cannot be referred to, e.g. in app manager, keep the
same behavior as before
