a7e63581b4 + i8086-msdos internal lniker: find the program entry point and fill it in the

cff94639d5 * i8086-msdos internal linker: improved handling of the _edata and _end internal 
symbols - add them to 'DGROUP' and define them in a section with class 'BSS'

fa8841d575 + support omf group-relative fixups pointing to external symbol (e.g. 
'wrt dgroup' references)

173713ce57 * preserve original order (as specified in the link script) of omf sections with 
the same name. This ensures that the startup code always comes first, which is
  important for .com files

fa9a1f706b + i8086-msdos internal linker: calculate the final segments and groups locations 
in memory (incl. segment bases) before DoRelocations; list segments and groups
  in the map file as well

5dc42404cf * capitalize omf segment class names, as that's how other 16-bit compilers write them

e09ab50724 * capitalize the group name 'DGROUP' in the generated omf object files, because 
that's how it is usually written by other 16-bit compilers

70677e3e44 + added a descendant class for omf section groups, which adds base address, size 
and a method to calculate these new fields

9aeb94676c + added virtual method to tobjsection for returning a string representation of 
the section's base address for the internal linker map file
* implemented it for omf sections to return the address in 'seg:ofs' format

nickysn
a762532ae1 * changed the MemPos field in TObjSection and TExeSection from aword to qword: 
1) aword follows the ALU size of the CPU, not the address size
  2) it is already qword in TExeOutput and its methods and there's already
     MaxMemPos to check if the limits of the platform/exe format have been
     exceeded

808b5dfb78 * allow gaps between LEDATA records, as nasm seems to produce them. They're 
automatically filled with zeros. This fixes reading of the tiny memory model
  startup code object module by the i8086-msdos internal linker.

7d586df038 * override DoRelocationFixup in TMZExeOutput - doing nothing for now, but 
prevents the "abstract method called" error

nickysn
d4b0b6f6e6 * use SegmentName+'||'+ClassName for the name of OMF sections when reading OMF 
files, because omf segments are (according to the spec) identified by the
  tuple <SegmentName,ClassName,OverlayName> and not just by name (and we ignore
  the overlay name)

add015f808 * ensure that the dwarf file table contains an entry if the current unit 
contains any code, even if we cannot generate any debug info for that
    code (because the default file is file number 1, and if that table is
    empty some gdb versions crash)

e06181749c * guarantee the order of parameter pushes again after r31201 on platforms 
that don't use a fixed stack (mantis #28454)
   o moved the code to finalise managed out parameters from ncgcal to ncal,
     and add it to the init code of the call node (so it's evaluated before
     any parameters are processed, ensuring that mantis #28390 stays fixed)

c95a3f2cf7 * firstpass rather than typecheckpass statements added to the call node 
init/done block, as these can be added while pass_1 is ongoing

41203a9152 * support far classrefdef targets on i8086 in thlcgcpu.a_loadaddr_ref_reg. This

  after r31064.

d4a4b9a57b * refactored the internal linker ar object reader object creation to allow using 
different 'ar' implementations under different platforms

8206c6dbd0 * the code for determining the code, data and bss sizes in the internal linker
