3fee990218 * on Mach-O, PECOFF and ELF platforms, write local symbols as hidden/ 
private_extern (or plain global in case of PECOFF, as the effect is
    the same there): visible across object files, but they become local
    when linked into a binary/library. This enables cross-unit inlining
    of functions accessig implementation-only symbols.

71cdedea82 Add missing NOP, and B instruction forms. 
Move ThumbFunc flag from section to symbol.
Make .w forms optional the other way around. If .w is explicitly put on an instruction the assembler should always chose a wide form.

a4053370fc * ELF linker: track relocation style (REL or RELA) of each input section and use it instead of global default on MIPS targets. This fixes internal linking of tests/test/units/system/tres*.pp.

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).

3cc8ff11e3 + generate the stack segment for i8086 far data memory models from within fpc 
itself (instead of having a fixed 16k stack in the startup code). This allows
  setting the stack size in these models with the -Cs option.

1f8a67f552 + Property TObjSymbol.ObjData, allows to access owning TObjData for external/common symbols, i.e. ones with ObjSection=nil. 
* For common symbols, report objdata of the original ObjSymbol, not of the resolving one, so the map file shows where it comes from.
+ TElfExeOutput.OrderOrphanSections method, handles object sections not mentioned in script similar to ld.
- t_linux.pas: removed sections that are not part of ld scripts, they are now handled by OrderOrphanSections.
