Handle mangled and decorated names

[coolkingcole]

It seems like it could be a nice feature to demangle/de-decorate names from pdbs. For example in this pdb:

https://msdl.microsoft.com/download/symbols/ntkrnlmp.pdb/00625D7D36754CBEBA4533BA9A0F3FE22/ntkrnlmp.pdb

Query:

{'name': 'ntkrnlmp.pdb', 'guid': '00625D7D36754CBEBA4533BA9A0F3FE2', 'age': 2, 'query': ['ExAllocatePoolWithTag']}

Result:

'{"ExAllocatePoolWithTag":-1}'

But this query resolves:

{'name': 'ntkrnlmp.pdb', 'guid': '00625D7D36754CBEBA4533BA9A0F3FE2', 'age': 2, 'query': ['_ExAllocatePoolWithTag@12']}

Result:

'{"_ExAllocatePoolWithTag@12":1146886}'

This could be a nice feature/enhancement. Could be a change in this repo or MolecularMatters/raw_pdb

Thank you so much for the issue. _ExAllocatePoolWithTag@12 is the decorated name of the stdcall function ExAllocatePoolWithTag. In addition to stdcall, C++ adds name decoration for function overloading. Therefore, to implement this functionality, it is necessary to add a new interface for converting function signatures to decorated names.

For the simple decorated names I just remove the underscore and everything after the @ symbol. You could use an existing library for more complicated symbols that start with a '?' like these:

https://github.com/ianlancetaylor/demangle

I'm sure there is a better way, but I just wrapped the rust library in a extern call so the name wouldn't be mangled and could be called from this project.
