* generic/tclStringObj.c: Replace the 'size_t uallocated' field

        of the String struct, storing the number of bytes allocated to store
        the Tcl_UniChar array, with an 'int maxChars' field, storing the
        number of Tcl_UniChars that may be stored in the allocated space.
        This reduces memory requirement a small bit, and makes some range
        checks simpler to code.

 	* generic/tclStringObj.c:	Removed limitation in
 	Tcl_AppendObjToObj where the char length of the result was only
 	computed if the appended string was all single byte characters.
