Jonas Maebe aee5380ae0 * merged trunk up to r20882
o support for the new codepage-aware ansistrings in the jvm branch
   o empty ansistrings are now always represented by a nil pointer rather than
     by an empty string, because an empty string also has a code page which
     can confuse code (although this will make ansistrings harder to use
     in Java code)
   o more string helpers code shared between the general and jvm rtl
   o support for indexbyte/word in the jvm rtl (warning: first parameter
     is an open array rather than an untyped parameter there, so
     indexchar(pcharvar^,10,0) will be equivalent to
     indexchar[pcharvar^],10,0) there, which is different from what is
     intended; changing it to an untyped parameter wouldn't help though)
   o default() support is not yet complete
   o calling fpcres is currently broken due to limitations in
     sysutils.executeprocess() regarding handling unix quoting and
     the compiler using the same command lines for scripts and directly
     calling external programs
   o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1
     to the make command line
