375f83c874 * moved heap manager on embedded systems into a separate unit 
* moved console io on embedded systems into a seperate unit, this unit might setup input/output e.g. to be redirected to a serial port
* cleanup of the embedded system unit

7cb1c8b586 * improvement of r16001 so that allocations even closer to high(ptruint) 
also fail correctly rather than overflowing to 0 bytes (mantis #18690)

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)

56f8b88125 * also initialise locgrowheapsizesmall in InitHeapThread, should fix crashes 
on Windows after r15618 (not sure why things worked fine elsewhere)

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.
