29bf988ca7 + Implemented m68k-specific (actually, softfloat-specific) part of Math unit.

0255eb880e - Removed mathuh.inc files which are identical for all targets (except m68k, see below), their contents moved into math.pp. 
+ m68k/mathu.inc: added stub implementations for missing functions.

83f4344c20 Fix around 30 tests for m68k by fixing FillChar: 
* completely disable the DBRA part for CPUs without DBRA
  * replace CMP/BNE with BPL which uses the flags of the SUB instruction
Additional fixes for the other two (still disabled) DBRA alternatives:
  * use BPL instead of BMI (which is wrong)

f5e94a02cd rtl/m68k/m68k.inc: 
* fillchar & fillword: check whether the count is 0 before filling anything

This fixes cases like "Writeln('')" which is used inside InternalExit if an unhandled exception happened.

e240856e43 * rtl/m68k/setjumph.inc: 
data registers stored are 1 to 7, not 0 to 7
* rtl/m68k/setjump.inc:
    don't use "S" or "value" to reference the parameters as the code generator does not use "sp" instead of "fp" in case of "nostackframe"
    restore a0 at the end of setjmp

4d1e42e891 rtl/m68k/setjump.inc:

f204f84f6a rtl/m68k/m68k.inc, move: 
completely disable the "fast loop" code for Coldfire instead of "hackfixing" it; with this StdIO starts to work (though one byte is missing at the end...)

58d9b0853c * rtl/m68k/m68k.inc, move: 
add a check for "count = 0" which happens e.g. inside of System.Assign if called with '' as filename (which is the case inside OpenStdIO)

a266d73409 * rtl/m68k/setjump.inc: 
correctly dummy out setjump as "d0 <> 0" means that longjmp was executed (and d0 could be set from the calling function)

322dbe5b65 Various adjustments to the RTL for m68k:

* add termios constants
* don't change signal handlers for now

8469741700 + Added additional addr pointer parameter to 
get_caller_frame, get_caller_addr and dump_stack
  with default NIL value to systemh.inc.
  + Added new get_addr function.
  system.inc: Use get_addr and get_frame to call
  HandleErrorAddrFrame instead of HandleErrorFrame
  in several error functions.
  Modify dump_stack to use frame and addr parameters.
  Provide a dummy get_addr function returning nil.
  i386/i386.inc, x86_64./x86_64.inc: Provide real
  implementation of get_addr function.
