eccbc78e04 + support for bitpacked arrays: 
+ use {$bitpacking on/+} to change the meaning of "packed"
      into "bitpacked" for arrays. This is the default for MacPas.
      You can also define individual arrays as "bitpacked", but
      this is not encouraged since this keyword is not known by
      other compilers and therefore makes your code unportable.
    + pack(unpackedarray,index,packedarray) to pack
      length(packedarray) elements starting at
      unpackedarray[index] into packedarray.
    + unpack(packedarray,unpackedarray,index) to unpack
      packedarray into unpackedarray, with the first
      element being stored at unpackedarray[index]
  * todo:
    * "open packed arrays" and rtti for packed arrays are not
      yet supported
    * gdb does not properly support bitpacked arrays

4506394cfa * pass contextobjdef for visibility of methods. There are different 
requirements for normal searching and for overloaded searching.
    For overloaded searching we need to have the context of the
    object where the overload is defined and not the current
    module

95be416b9d * don't allow stringconst+integer

    a nicer type can be shown instead of array[0..x] of char

765fe2b2ab * fixed bug #4737 (check for potential range errors in for-loop 
assignment, report correct column for potential range errors of
    call parameters)
  * refactored code to check potential range check errors (check_ranges
    in htypechk)

parent procedures in nested procedures (bug 4675)

Jonas Maebe
9bb86eb411 * never make vs_var or vs_out variabled non-regable, unless it's an 
access from a nested procedure. This allows keeping the address
    of large function results like shortstrings in a register,
    because they were always made non-regable by a typeconversionnode
    due to the fact that they are aliased by an absolute alias.

857664a5d4 * fixed tw4554: 
* proper uninitialized checking for arrays
    * first check uninitialized status of right side of assignment
      before setting the left side to "written" (-> catch "x:=x" if
      x is uninitialized)

42ec76598c * new categories for vs_*: vs_declared, vs_initialised, vs_read, 
vs_written, vs_readwritten. vs_initialised is the old vs_assigned;
    vs_used has been replaced by vs_read, vs_written and vs_readwritten
  * the valid_for_*() routines in htypechk now get an extra parameter to
    decide whether or not errors should be reported
