Message:

Runtime/common/dbg: Implement basic debug info reader for XML files created by Ghidra's createPdbXmlFiles.bat script in order to get more accurate symbols when debugging Windows guests on hosts other than Windows due to the lack of a dbghelp.dll equivalent for accessing the debugging information inside of PDB files. This requires creating the XML files on a Windows machine with a matching set of PDB files. XML files can be loaded with the loadmap debugger command for now (automatic loading not implemented right now)
