 * TclStringReplace --
 *
 *	Implements the inner engine of the [string replace] command.
 *
 *	The result is a concatenation of a prefix from objPtr, characters
 *	0 through first-1, the insertPtr string value, and a suffix from
 *	objPtr, characters from first + count to the end. The effect is
 *	as if the inner substring of characters first through first+count-1
 *	are removed and replaced with insertPtr.
 *	If insertPtr is NULL, it is treated as an empty string.
 *	When passed the flag TCL_STRING_IN_PLACE, this routine will try
 *	to do the work within objPtr, so long as no sharing forbids it.
 *	Without that request, or as needed, a new Tcl value will be allocated
 *	to be the result.
 *
 * Results:
 *	A Tcl value that is the result of the substring replacement.
 *	May return NULL in case of an error. When NULL is returned and
 *	interp is non-NULL, error information is left in interp
