kDepObj: Parse object files for dependencies

[bird]

Some object files may contain dependency information and it would be good to extract it. The Watcom and Borland compiler emits COMMENT class 0xE9 records containing dependency info with a low resolution time stamp. MASM emits THEADR records for each include file it encounters if told to emit line number information (/Zd) or symbolic debug info (/Zi) (OMF format at least). Other compilers, assemblers and object formats should be investigated as necessary.

(In [2267]) kDepObj: Taught it how to parse .debug$S section and find the source file info. CV8 and Visual C++ 2005 and later (+YASM). Not quite polished up yet, work in progress. References #82.
