5b47bad32a * use uppercase object section names in the OMF linker script for matching the 
dwarf debug sections. This is because they are converted to upper case when
  reading (so that we treat omf section names as case-insensitive)

file on i8086-msdos and i8086-win16

b80642c384 + started implementing support for generating Microsoft CodeView debug 
information. Only enabled on i8086 (for now). Does not do much yet, but
  hopefully, soon it'll start emitting line number information for i8086-msdos
  that is usable by DOS debuggers.

125360ca16 * fixed the amount of bytes in the 'data' section, reported by the compiler, 
when compiling an msdos executable in the huge memory model with the internal
  linker (previously it would always print "0 bytes data" in the huge memory
  model)

4061628ffb * the i8086-msdos default code segment (in near code memory models) renamed 
'_TEXT'. This name is used in object modules, produced by Borland C and Open
  Watcom.

7cfd7a66cd + create a special 'heap' segment with reserved space equal to heapsize (i.e. 
the value set by -Ch or the second parameter to the $M directive). This is
  equivalent to the heapmin value in Turbo Pascal 7 and ensures that the program
  has at least this amount of heap space available (otherwise DOS will show a
  'not enough memory' error and will refuse to load the program).

49f93b4464 * use the 'order' wlink directive to specify the segment order, instead of using 
'option dosseg'. This allows us more flexibility in setting up the segment
  order the way we like.

567cdf875b + added new i8086 compiler options -Wtexe and -Wtcom for specifying the MS-DOS 
binary format (.exe or .com)
* the default format for i8086 tiny model binaries changed to .exe

38058505ba * Changed linking infrastructure to look like assembler one: 
* Changed direct references to linker classes in TSystemInfo records to enumerated ids.
  * RegisterExtennalLinker and RegisterInternalLinker procedures replaced by single RegisterLinker procedure and moved to link.pas.
  - TAbstractLinker is no longer necessary, removed.

This change allows to register linker once per id, rather than once per target, and also allows TSystemInfo records to be read-only.
