9cec910eb9 * changed *string_to_*chararray helpers from functions into procedures 
because on win64 the location of a function result can depend on its
    size (so some chararrays had to be returned in registers and others
    by reference, which means it's impossible to have a generic function
    declaration which works in all cases) (mantis #8533)
  * pad constant string assignments to chararrays with #0 up to the
    length of the chararray for 2.0.x compatibility (fixes
    tests/test/tarray3)

a2c3826281 * changed fpc_big_chararray and fpc_big_widechararray from 
array[0..1023] into array[0..0], because they're used as
    dummy return types for the Xstring_to_chararray helpers,
    and if a smaller array is actually passed as result then
    having a larger array declared will cause -gt to
    overwrite other data

2f0ce31751 * string concat changed from function to procedure to 
allow runtime optimization if the destination is the
    same as a source parameter
  * tassignmentnode now sets aktassignmentnode global that can be used
    to use the left node as a destination parameter and
    skip the assignment
  * disabled all cpu specific shortstr concat/append

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.
