wamr-python: Enable debugging WASM and grant dir access (#2449) 
- Enable debugging a WASM loaded and executed from Python.
- Expose API to enable access to list of host directories. Similar to --dir in iwasm.
- Add another python language binding sample: native-symbol.

Native Symbol

This sample demonstrates how to declare a Python function as NativeSymbol.

Steps of the example:

  1. Load WASM from Python
  2. Call c_func from WASM.
  3. c_func calls python_func from Python.
  4. python_func calls add from WASM.
  5. Result shown by Python.

Build

Follow instructions build wamr Python package.

Compile WASM app example,

./compile.sh

Run sample

python main.py

Output:

python: calling c_func(10)
c: in c_func with input: 10
c: calling python_func(11)
python: in python_func with input: 11
python: calling add(11, 1000)
python: result from add: 1011
c: result from python_func: 1012
c: returning 1013
python: result from c_func: 1013
