that source_path doesn't contain the current_directory from when
GDB started up, init_source_path is no longer useful (and is

LOC_REF_ARG.

Remove indexNil check from caller of parse_type.

value is the size of the common, not its address.
Handle scInit, scFini, scPData and scXData sections.
Use minimal symbol type mst_file_* for stLabel symbols, instead of
mst_*.
Enter stProc symbols into the global_psymbols list once, not into
