a72434e93a Trial to clarify heap for i8086 issues: 
- MSDOS heap in tinyheap.inc modified to use usual
  SysGetMem and similar names.
  - Use HAS_MEMORYMANAGER (used previously in wince source code,
  to specify that a memory manager is defined elsewhere than inside
  heap.inc include file.
  - Use
  - Remove TinyHeapMemoryManager Structure variable completely

  heaptrc.pp: remove unneeded macro code after name changes of tinyheap.inc

  msdos/system.pp now only defines HAS_MEMORYMANAGER macro
  win16/system.pp defines HAS_MEMORYMANAGER and FPC_NO_DEFAULT_HEAP
  as it still uses a different memory manager.
  __stkbottom variable added for win16 system.pp as it is required
  by i8086 specific stack check code.

759a4f8258 * don't try to build lnfodwrf on i8086-msdos, because it causes internal error 
200309041 and thus breaks building i8086-msdos snapshots entirely. Added test
  that reproduces the bug in a small program, so it can be fixed eventually.

4454332d7a * fixed the sysutils.GetEnvironment* functions for i8086-msdos 
- removed the envp variable from the msdos system unit, because it's not
  compatible with ppchar in all memory models (we use ppfarchar to avoid copying
  the environment in the program's data segment in near data memory models)

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

536346a441 * use 'dw' instead of 'dd' to reference the stack, in order to prevent nasm from

3ee0fc22d9 * use 'dw' instead of 'dd' to reference the heap from the i8086-msdos startup 
code, because 'dd' causes nasm to emit a 32-bit OMF relocation entry, which
  we won't support (at least initially) in our internal linker

45ed066fed * fixed SysUtils.FindFirst/FindNext/FindClose on i8086-msdos in the compact and 
large memory models by changing TSearchRec.FindHandle to a pointer (because
  THandle is 16-bit on this platform and is thus not able to hold a far pointer
  without truncating it)

7958466ef9 * on i8086-msdos, in the compact and large memory models, set the end of heap to

9979aa702f + added the TP7-compatible pointer variables HeapOrg and HeapEnd, indicating, 
respectively, the start and end of the tiny heap. Eventually they are also
  going to be used for catching attempts to free memory that is outside the
  heap.
