Follow-up on #2907. The log level is needed in the host embedder to
better integrate with the embedder's logger.
Allow the developer to customize his bh_log callback with
`cmake -DWAMR_BH_LOG=<log_callback>`,
and update sample/basic to show the usage.
In linux x86-64, developer can use cmake variable to configure whether
to enable writing linear memory base address to x86 GS register or not:
- `cmake -DWAMR_DISABLE_WRITE_GS_BASE=1`: disabled it
- `cmake -DWAMR_DISABLE_WRITE_GS_BASE=0`: enabled it
- `cmake` without `-DWAMR_DISABLE_WRITE_GS_BASE=1/0`:
auto-detected by the compiler
For shared memory, the max memory size must be defined in advanced. Re-allocation
for growing memory can't be used as it might change the base address, therefore when
OS_ENABLE_HW_BOUND_CHECK is enabled the memory is mmaped, and if the flag is
disabled, the memory is allocated. This change introduces a flag that allows users to use
mmap for reserving memory address space even if the OS_ENABLE_HW_BOUND_CHECK
is disabled.
In some scenarios there may be lots of callings to AOT/JIT functions from the
host embedder, which expects good performance for the calling process, while
in the current implementation, runtime calls the wasm_runtime_invoke_native
to prepare the array of registers and stacks for the invokeNative assemble code,
and the latter then puts the elements in the array to physical registers and
native stacks and calls the AOT/JIT function, there may be many data copying
and handlings which impact the performance.
This PR registers some quick AOT/JIT entries for some simple wasm signatures,
and let runtime call the entry to directly invoke the AOT/JIT function instead of
calling wasm_runtime_invoke_native, which speedups the calling process.
We may extend the mechanism next to allow the developer to register his quick
AOT/JIT entries to speedup the calling process of invoking the AOT/JIT functions
for some specific signatures.
On macOS, by default, the first 4GB is occupied by the pagezero.
While it can be controlled with link time options, as we are
an library, we usually don't have a control on how to link an
executable.
And refactor the original perf support
- use WAMR_BUILD_LINUX_PERF as the cmake compilation control
- use WASM_ENABLE_LINUX_PERF as the compiler macro
- use `wamrc --enable-linux-perf` to generate aot file which contains fp operations
- use `iwasm --enable-linux-perf` to create perf map for `perf record`
This PR implements the WebAssembly stringref proposal:
https://github.com/WebAssembly/stringref
It adds cmake variable `WAMR_BUILD_STRINGREF` to build the feature,
which will enable GC automatically.
The stringref contains two parts:
- `part 1`: add new ref types in WasmGC, add opcode processing in loader and interpreter
- `part 2`: add a library for string representation/encoding/decoding and so on
To reduce the code size introduced to WAMR, this PR only includes `part 1`,
`part 2` can be provided by embedder, they may use their own implementation,
e.g., Wasmnizer-ts uses JSString from QuickJS to implement stringref:
https://github.com/intel/Wasmnizer-ts/blob/main/runtime-library/stringref/stringref_qjs.c
We will submit another PR of `part 2` and make it as a sample rather than WAMR core part.

Send a signal whose handler is no-op to a blocking thread to wake up
the blocking syscall with either EINTR equivalent or partial success.
Unlike the approach taken in the `dev/interrupt_block_insn` branch (that is,
signal + longjmp similarly to `OS_ENABLE_HW_BOUND_CHECK`), this PR
does not use longjmp because:
* longjmp from signal handler doesn't work on nuttx
refer to https://github.com/apache/nuttx/issues/10326
* the singal+longjmp approach may be too difficult for average programmers
who might implement host functions to deal with

Add cmake varaible WAMR_BUILD_AOT_STACK_FRAME and auto enable it for
dump-call-stack and perf-profiling features. Extend WASMCApiFrame and
commit more data to it in dump-call-stack.
Commit stack pointer and instruction pointer when calling functions.
Enable setting callback when exception is thrown for debug purpose.
Introduce module instance context APIs which can set one or more contexts created
by the embedder for a wasm module instance:
```C
wasm_runtime_create_context_key
wasm_runtime_destroy_context_key
wasm_runtime_set_context
wasm_runtime_set_context_spread
wasm_runtime_get_context
```
And make libc-wasi use it and set wasi context as the first context bound to the wasm
module instance.
Also add samples.
Refer to https://github.com/bytecodealliance/wasm-micro-runtime/issues/2460.
Allow to use `cmake -DWAMR_CONFIGURABLE_BOUNDS_CHECKS=1` to
build iwasm, and then run `iwasm --disable-bounds-checks` to disable the
memory access boundary checks.
And add two APIs:
`wasm_runtime_set_bounds_checks` and `wasm_runtime_is_bounds_checks_enabled`
LLVM PGO (Profile-Guided Optimization) allows the compiler to better optimize code
for how it actually runs. This PR implements the AOT static PGO, and is tested on
Linux x86-64 and x86-32. The basic steps are:
1. Use `wamrc --enable-llvm-pgo -o <aot_file_of_pgo> <wasm_file>`
to generate an instrumented aot file.
2. Compile iwasm with `cmake -DWAMR_BUILD_STATIC_PGO=1` and run
`iwasm --gen-prof-file=<raw_profile_file> <aot_file_of_pgo>`
to generate the raw profile file.
3. Run `llvm-profdata merge -output=<profile_file> <raw_profile_file>`
to merge the raw profile file into the profile file.
4. Run `wamrc --use-prof-file=<profile_file> -o <aot_file> <wasm_file>`
to generate the optimized aot file.
5. Run the optimized aot_file: `iwasm <aot_file>`.
The test scripts are also added for each benchmark, run `test_pgo.sh` under
each benchmark's folder to test the AOT static pgo.
Add nightly (UTC time) checks with asan and ubsan, and also put gcc-4.8 build
to nightly run since we don't need to run it with every PR.

Add VX delegation as an external delegation of TFLite, so that several NPU/GPU
(from VeriSilicon, NXP, Amlogic) can be controlled via WASI-NN.
Test Code can work with the X86 simulator.
- Remove notify_stale_threads_on_exception and change atomic.wait
to be interruptible by keep waiting and checking every one second,
like the implementation of poll_oneoff in libc-wasi
- Wait all other threads exit and then get wasi exit_code to avoid
getting invalid value
- Inherit suspend_flags of parent thread while creating new thread to
avoid terminated flag isn't set for new thread
- Fix wasi-threads test case update_shared_data_and_alloc_heap
- Add "Lib wasi-threads enabled" prompt for cmake
- Fix aot get exception, use aot_copy_exception instead
Remove restrictions:
- Only 1 WASM app at a time
- Only 1 model at a time
- `graph` and `graph-execution-context` are ignored

Support collecting code coverage with wamr-test-suites script by using
lcov and genhtml tools, eg.:
cd tests/wamr-test-suites
./test_wamr.sh -s spec -b -P -C
The default code coverage and html files are generated at:
tests/wamr-test-suites/workspace/wamr.lcov
tests/wamr-test-suites/workspace/wamr-lcov.zip
And update wamr-test-suites scripts to support testing GC spec cases to
avoid frequent synchronization conflicts between branch main and dev/gc.
The latest GC spec proposal has changed a lot since we implemented the feature,
refactor it based on the main branch. Part of the spec cases were tested.
Implement 2-level Multi-tier JIT engine: tier-up from Fast JIT to LLVM JIT to
get quick cold startup by Fast JIT and better performance by gradually
switching to LLVM JIT when the LLVM JIT functions are compiled by the
backend threads.

`_ZN4llvm30TargetTransformInfoWrapperPass2IDE' can not be used when making a PIE object;
recompile with -fPIC
Add `-fPIC` to `CMAKE_CXX_FLAGS` and `CMAKE_SHARED_LIBRARY_LINK_C_FLAGS` to fix it.
Enable bulk memory by default since it is a finished wasm spec proposal
and is enabled by default in latest wasi-sdk. Developer often encounters
"invalid section id" or "unsupported opcode" error if it isn't enabled.
Use sha256 to hash binary file content. If the incoming wasm binary is
cached before, wasm_module_new() simply returns the existed one.
Use -DWAMR_BUILD_WASM_CACHE=0/1 to control the feature.
OpenSSL 1.1.1 is required if the feature is enabled.
Add an option to pass user data to the allocator functions. It is common to
do this so that the host embedder can pass a struct as user data and access
that struct from the allocator, which gives the host embedder the ability to
do things such as track allocation statistics within the allocator.
Compile with `cmake -DWASM_MEM_ALLOC_WITH_USER_DATA=1` to enable
the option, and the allocator functions provided by the host embedder should
be like below (an extra argument `data` is added):
void *malloc(void *data, uint32 size) { .. }
void *realloc(void *data, uint32 size) { .. }
void free(void *data, void *ptr) { .. }
