Unbreak builds with a bit older nuttx/apps for now.
Note: The default value here (0) was chosen to match the new default
in nuttx/apps, which is different from the old value used before
the introduction of WASM_STACK_GUARD_SIZE. (1024)
ASSERT_NOT_IMPLEMENTED is bh_assert, which might be no-op.
in that case, it's better to fall back to the "default" case,
which reports an error properly.
Fix the following warning introduced by the recent change.

This header file is supposed to be used by user code, which is not
a part of WAMR. Usually WAMR configuration is not available there,
remove DEBUG_INTERP macro control in it.
Fix the symbol resolving failure with recent version of wamrc:
```
AOT module load failed: resolve symbol .Lswitch.table.aot _func#82.2 failed
```
Replace the relocations for such symbols with .rodata section.
Add assertion for BH_MALLOC/BH_FREE in wasm_runtime_common.c,
when building runtime, the BH_MALLOC/BH_FREE macros should be
defined as wasm_runtime_malloc/wasm_runtime_free.
Fix an UBSan complaint introduced by recent change by adding more checks
to word_copy:
```
wasm_interp_fast.c:792:9: runtime error: applying zero offset to null pointer
```
Fix the following warning when loading an aot file without relocations:
```
[20:19:00:528 - 1119F1600]: warning: wasm_runtime_malloc with size zero
```
Fix issues in PR "Refine interp/aot string storage and emitting (#820)",
which had a few issues:
- It looks a wrong byte to mark the flag
- It doesn't work for long strings (>= 0x80 in case of little endian)
This commit fixes them by maintaining a list of loaded symbols while loading
relocation section to avoid reading a string repeatedly, and no need to mark
the flag again.
Fix compile warnings in libc-wasi posix.c:
```
posix.c:880:41: warning: comparison of integers of different signs:
'unsigned long' and 'ssize_t' (aka 'long') [-Wsign-compare]
if (bufoff + iov[i].buf_len < len) {
posix.c:1359:32: warning: comparison of integers of different signs:
'off_t' (aka 'long long') and 'unsigned long long' [-Wsign-compare]
if (ret == 0 && sb.st_size < offset + len)
```
The size used to apply "size = align_uint(size, 4)" may be different
when calculating total size (in get_object_data_sections_size) and
emitting actual data (in aot_emit_object_data_section_info) for the
object data section.
This patch fixes the "Error: emit object data section info failed".
The last argument arg of pthread_create passed from wasm app is opaque
for the library and host, it should be returned back to the wasm app without
any interpretation. There is no point to translate it to a native address.
Actually it harms because the validation seems broken.
