1. The input consists of multiple static libraries and an ELF file. The tool searches
for external APIs used by the static libraries, then locates these API function signatures
in the ELF file, and outputs the results as a JSON file.
2. Using the first feature, with the static libraries unchanged,
the tool can take a new ELF file and an old ELF file as input, output two JSON files,
and compare the function signatures of functions with the same name in the two JSON files.
The comparison includes return values, parameters, and if they are structures,
it also compares the structure size, member offsets, member types, etc.
3.When the input is a single ELF file, the tool can check if structures with the same name have different members.
