47eb589d54 * allow implicit conversions from/to packed char arrays under the 
same conditions as from/two regular char arrays (since a packed
    char array is the same as a string in ISO Pascal)

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
