Refactor AOT loader to support compatible versions ( #3891 )
...
This commit refactors the AOT loader in `aot_loader.c` to support compatible
versions of the AOT_CURRENT_VERSION constant. Previously, the loader only
accepted the exact AOT_CURRENT_VERSION value, but now it also accepts
version 3. This change ensures that the runtime can load modules AoT-compiled
with different versions of wamrc as long as they have compatible
AOT_CURRENT_VERSION values.
Related to #3880 .

Allow not copying the wasm binary in wasm-c-api and not referring to the binary in wasm/aot loader ( #3389 )

Add flag `LoadArgs.clone_wasm_binary` to control whether to clone the wasm/aot
binary in wasm-c-api module. If false, API `wasm_module_new_ex` won't clone the
binary, which may reduce the footprint.
Add flag `LoadArgs.wasm_binary_freeable` to control whether the wasm/aot binary
may be freed after instantiation for wamr API `wasm_runtime_load_ex`, if yes, then
for some running modes, the wasm/aot module doesn't refer to the input binary
again so developer can free it after instantiation to reduce the footprint.
And add API `wasm_module_is_underlying_binary_freeable` and
`wasm_runtime_is_underlying_binary_freeable` to check whether the input binary
can be freed after instantiation for wasm-c-api and wamr api.
And add sample to illustrate it.

User defined memory allocator for different purposes ( #3316 )
...
Some issues are related with memory fragmentation, which may cause
the linear memory cannot be allocated. In WAMR, the memory managed
by the system is often trivial, but linear memory usually directly allocates
a large block and often remains unchanged for a long time. Their sensitivity
and contribution to fragmentation are different, which is suitable for
different allocation strategies. If we can control the linear memory's allocation,
do not make it from system heap, the overhead of heap management might
be avoided.
Add `mem_alloc_usage_t usage` as the first argument for user defined
malloc/realloc/free functions when `WAMR_BUILD_ALLOC_WITH_USAGE` cmake
variable is set as 1, and make passing `Alloc_For_LinearMemory` to the
argument when allocating the linear memory.

Implement GC (Garbage Collection) feature for interpreter, AOT and LLVM-JIT ( #3125 )
...
Implement the GC (Garbage Collection) feature for interpreter mode,
AOT mode and LLVM-JIT mode, and support most features of the latest
spec proposal, and also enable the stringref feature.
Use `cmake -DWAMR_BUILD_GC=1/0` to enable/disable the feature,
and `wamrc --enable-gc` to generate the AOT file with GC supported.
And update the AOT file version from 2 to 3 since there are many AOT
ABI breaks, including the changes of AOT file format, the changes of
AOT module/memory instance layouts, the AOT runtime APIs for the
AOT code to invoke and so on.

Always allocate linear memory using mmap ( #3052 )
...
With this approach we can omit using memset() for the newly allocated memory
therefore the physical pages are not being used unless touched by the program.
This also simplifies the implementation.

Forward log and log level to custom bh_log callback ( #3070 )
...
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.

Fix a bug when emit the custom name section to aot file ( #2987 )
...
The content in custom name section is changed after loaded since the strings
are adjusted with '\0' appended, the emitted AOT file then cannot be loaded.
The PR disables changing the content for AOT compiler to resolve it.
And disable emitting custom name section for `wamrc --enable-dump-call-stack`,
instead, use `wamrc --emit-custom-sections=name` to emit it.
