Refine wasm_interp_interp_frame_size to reduce the wasm operand stack usage

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.
This patch allows safer (note: safer, not safe) embedding in a plugin
environment where multiple instances of the engine could be needed.
Original code initializes and tears down the full runtime during
wasm_engine_new() and wasm_engine_delete() respectively. After this
update the C API implementation keeps track of engine instances count
and inits/deinits the runtime only when needed.
This allows for example to call wasm_engine_new() twice and then call
wasm_engine_delete() once without rendering the first engine instance
invalid.
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`.

- 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 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.
In some Linux systems whose kernel version is smaller than 2.6.38, the macro
MADV_HUGEPAGE isn't introduced yet which causes compilation error.
Add macro control to fix the compilation error.
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

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.
Allow compilation on Windows MinGW, see build_wamr.md for more details.
Note that WASI and some other smallish details are still not supported, but
we have a starting point. See more discussion at #993
Implement pthread_cond_broadcast wrapper for lib-pthread
- support pthread_cond_broadcast wrapper for posix/linux-sgx/windows

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.

- fix os_malloc/os_realloc/os_free issues
- implement os_thread_get_stack_boundary
- add build scripts to include with esp-idf to use wamr as

- update sample and document
Refer to https://github.com/WebAssembly/WASI/blob/main/design/application-abi.md
to check the WASI ABI compatibility:
- Command (main module) may export _start function with signature "()"
- Reactor (sub module) may export _initialize function with signature "()"
- _start and _initialize can not be exported at the same time
- Reactor cannot export _start function
- Command and Reactor must export memory
And
- Rename module->is_wasi_module to module->import_wasi_api
- Refactor wasm_loader_find_export()
- Remove MULTI_MODULE related codes from mini_loader
- Update multi-module samples
- Fix a "use-after-free" issue. Since we reuse the memory instance of sub module,
just to protect it from freeing an imported memory instance
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

the fix works correctly.
- 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

This PR introduces an implementation of the WAMR platform APIs for ESP-IDF and enables support for Espressif microcontrollers, and adds the documentation around how to build WAMR for ESP-IDF.
This PR is related to the following issues at WAMR: closes#883, #628, #449 and #668 as well as [#4735](https://github.com/espressif/esp-idf/issues/4735) at the esp-idf repo. It implements most functions required by [platform_api_vmcore.h](https://github.com/bytecodealliance/wasm-micro-runtime/blob/main/core/shared/platform/include/platform_api_vmcore.h).
The PR works in interpreter mode on Esp32c3 and Esp32. For the AOT mode, currently errors occur on both platforms with `Guru Meditation Error`. It seems that the AOT code isn't run with shared memory as os_mmap() allocates memory with malloc() API, it is to be fixed in the future.
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.
Update spec test cases to commit 2460ad02b51fb5ed5824f44de287a8638b19a5f8,

or there are many senseless error logs
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.
The debug_instance_list is not protected by mutex, and the debug instance uses

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
