 * Tcl_InitStringRep --
 *
 *	This function is called in several configurations to provide all
 *	the tools needed to set an object's string representation. The
 *	function is determined by the arguments.
 *
 *	(objPtr->bytes != NULL && bytes != NULL) || (numBytes < 0)
 *	    Invalid call -- panic!
 *
 *	objPtr->bytes == NULL && bytes == NULL && numBytes >= 0
 *	    Allocation only - allocate space for (numBytes+1) chars.
 *	    store in objPtr->bytes and return. Also sets
 *	    objPtr->length to 0 and objPtr->bytes[0] to NUL.
 *
 *	objPtr->bytes == NULL && bytes != NULL && numBytes >= 0
 *	    Allocate and copy. bytes is assumed to point to chars to
 *	    copy into the string rep. objPtr->length = numBytes. Allocate
 *	    array of (numBytes + 1) chars. store in objPtr->bytes. Copy
 *	    numBytes chars from bytes to objPtr->bytes; Set
 *	    objPtr->bytes[numBytes] to NUL and return objPtr->bytes.
 *	    Caller must guarantee there are numBytes chars at bytes to
 *	    be copied.
 *
 *	objPtr->bytes != NULL && bytes == NULL && numBytes >= 0
 *	    Truncate.  Set objPtr->length to numBytes and
 *	    objPr->bytes[numBytes] to NUL.  Caller has to guarantee
 *	    that a prior allocating call allocated enough bytes for
 *	    this to be valid. Return objPtr->bytes.
 *
 *	Caller is expected to ascertain that the bytes copied into
 *	the string rep make up complete valid UTF-8 characters.
