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.

bcbd25568e * Call InitHeap before InitSystemThreads in TLS callback (necessary because InitSystemThreads calls RelocateHeap), and skip both of them in initialization section of system.pp if they have been called from TLS callback. This restores correct initialization sequence which was broken by r19779, resulting in lots of debug messages about corrupted heap when running tests/test/theapthread.pp

242016312f * immediately fail when trying to allocate a memory block whose size falls 
in the range high(ptruint)-$fffe .. high(ptruint), because all large
    allocations are rounded up to the next multiple of 64kb, which is 0 in
    that case (mantis #17430)

e150c2c521 * dynamically grow the size of oschunks allocated for use by the memory 
pools for small blocks (fixedfreelists) when lots of such oschunks
    are allocated successively, in order to reduce the overhead of
    allocating such chunks from the OS (and of freeing them afterwards)

8a891690cc * prefetch heap status in sysfreemem 
* re-layouted code in sysfreemem_fixed so that the most likely case is on
    the fall-through path
  * moved dec(poc^.used) in sysfreemem_fixed earlier so that it doesn't
    cause a dependency stall for the "if poc^.used<=0" test later

0597c300f4 * applied feature dependencies patch by Sven Barth from mantis #13673 : 
o i386/i386.inc used a function (fpc_truely_ansistr_unique) is now
     only included if FPC_HAS_FEATURE_ANSISTRINGS is enabled (all other
     platforms use the Pascal-only implementations)
   o inc/heap.inc relied on threading
   o inc/threads.inc relied on exceptions, consoleio and stackcheck
   o inc/system.inc: just a feature-related "variable not used"-hint

eb83213f10 * Only start recycling oschunks once MaxKeptOSChunks chuncks have 
been allocated. E.g. allocate 100 blocks of 80 bytes and free them
    all, then the same with blocks of 96, 112, 128, 144, 160 and 176
    bytes, after which again 80 bytes -> previously, regardless of
    the value of MaxKeptOSChunks, the empty block for 80 bytes was
    reformatted for those of 96 bytes, then for 112 bytes etc. Now,
    if MaxKeptOSChunks is set to 7, none will ever be reformatted
    because enough chunks will be allocated from the OS.
