0eb9dd3879 * Darwin support for printing line info for backtraces when using Dwarf, 
based on patches by Colin Western, mantis #38483)
   o requires that the program/library is compiled with -Xg (or that
     dsymutil is run on it after compiling), and that the .dSYM bundle
     is in the same directory as the program/library
   o always use the "dl" unit in exeinfo for Darwin, as that's needed for
     dynamic library support, and this does not cause an extra dependency
     since on Darwin we always use libc
   o cleaned up the exeinfo unit for Darwin, and sped it up by using mmap
     instead of small reads
   o fixed unit dependencies for exeinfo, lineinfo and lnfodwarf in Darwin
     RTL Makefile
  * use the process address info from the original exe even when reading
    the debug information from an external file
  - removed outdated ifdef'd darwin code from dl.pp (no longer needed now
    that processaddress gets set correctly in exeinfo for that platform)

2c000d1e74 * processaddress's type changed to word on i8086 (ptruint changes size between 
memory models and we only need the offset; the segment is tracked separately)
+ introduce texefile.processsegment on i8086
* initialize processaddress and processsegment properly on i8086-msdos (for .exe
  files; .com files are not supported yet)

c8cbb1daea * changed the sechdrofs,secstrofs and ImgOffset types to 32-bit to prevent 
overflow errors on i8086 (ptruint is 16-bit in certain i8086 memory models;
  file offsets, however, still remain 32-bit)

537fbefb9e * add texeheader.ImgOffset to all file offsets when reading an ELF file. This 
will be useful for reading i8086-msdos dwarf debug info, because it is
  appended after the regular dos MZ exe in an ELF32 image by the watcom linker.

8a940151a7 o patch by Sergej Gorelkin: 
* When OpenExeFile is called with an empty filename argument, 
    it apparently opens stdin and crashes immediately thereafter trying to seek in non-seekable stream. 
    The filename is empty whenever GetLineInfo is called with the address that does not belong to valid module.
