58381ff7b6 * made chararray handling 98% TP-compatible, fixes web bugs 3012 
and 4080. The compatibility differences are:
      a) writing a chararray which is zero-based but not zero-
         terminated does not cause a buffer overflow
      b) non-zero-based chararrays can also be read

    The difference was that previously, all chararrays were treated
    as pchars. In TP/Delphi (and now also in FPC), this is only done
    for zero-based chararrays. For non-zero-based ones, the entire
    contents of the array should always be used (including #0's).

    The default parameters in the system unit for the chararray
    helpers are to avoid having to use a define for bootstrapping.

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    vs_used has been replaced by vs_read, vs_written and vs_readwritten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
