0d48e5f6c7 + added support to the omf/i8086-msdos internal linker for omf relocation with 
location type 3 (fltFarPointer). This isn't generated by nasm, nor by the
  internal object writer (yet), but may be generated by other
  assemblers/compilers - TASM generates it (tested with it), MASM probably also
  does.

991e1f49bd * store a pointer to the used tasminfo record in every assembler writer, so 
that we can use assembler writers with different conventions from the
    currently set target_asm (e.g. an x86 assembler writer for inline assembly
    in LLVM IR)

cc2e27b555 * the function which returns the alignment of omf sections moved to unit 
omfbase, so it can be used by the nasm asm writer as well

3abfa177c4 * initialization of stack and dwarf debug omf sections moved from

efef3882a0 * moved the code for determining whether an omf object section should 
belong to group DGROUP to a function in unit omfbase (so it can be used in the

4061628ffb * the i8086-msdos default code segment (in near code memory models) renamed

nickysn
2431b6e63b * i8086-msdos internal linker: use a different approach for finding the stack

808b5dfb78 * allow gaps between LEDATA records, as nasm seems to produce them. They're

d4b0b6f6e6 * use SegmentName+'||'+ClassName for the name of OMF sections when reading OMF
