inbetween

3e343dff21 + enable by default the ds_dwarf_omf_linnum debug switch on i8086, since that's 
the only currently working option for getting source level debugging on
  i8086-msdos

nickysn
600b460ecd + added new debug output option -godwarfomflinnum for generating line number 
information in OMF LINNUM records, in addition to the DWARF debug information.
  This enables source level debugging on i8086-msdos, when using the Open Watcom
  Debugger, provided the source was compiled with this option and the external
  linker (wlink) was used for generating the executable (the internal linker
  does not yet support generating debug information).

entries in the OMF object format

nickysn
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.

nickysn
0b296ac828 * extracted the parts of the TOmfRecord_LINNUM_MsLink class, which implement a 
container of TOmfSubRecord_LINNUM_MsLink_Entry objects to a separate class
  TOmfSubRecord_LINNUM_MsLink_LineNumberList

718e83954f * merge duplicate strings in the LNAMES section, when writing OMF object

760e1f3776 * default namespaces are specified using the new -FN<x> option whereby <x> is the namespace to be added to the 
list of default namespaces

8bc0b604db * a symbol might be specified using a partial namespace path as long as the missing part is a namespace symbol, 
so handle that correctly in try_consume_unitsym()

35bddf6fb1 * correctly update the (now unregistered) unit symbol if the unit was found with the help of a default namespace 
(this is needed to trigger the correct creation of the namespace symbols)

svenbarth
99c53abf36 * also take into account default namespace when looking for a unit: 
if looking for a unit's PPU or source failed (and no explicit name was specified)
    then all namespaces are walked in the order they were given in and then first the
    PPU is looked for and then the source

c0dcb505e2 * use the module's filename instead of the passed in name (we assume all units added that way don't use the 
ability to have a different module name to their filename)

c530e031b1 * synchronize get_saved_registers_int and get_volatile_registers_int for all 
calling conventions on i386
* generated code at the caller side for pocall_pascal routines on i386 no longer
  assumes the routine destroys all registers (except ebp) - instead now it
  assumes that it preserves the ebx,esi,edi and ebp registers. This is
  compatible with the pascal calling convention of 32-bit delphi and was already
  honoured by FPC on the callee side.
* updated the list of calling conventions that save all registers, used in
  tx86callnode.can_call_ref, so it is accurate on all x86 platforms - i8086,
  i386 and x86_64.
