* [2992970] Restore the safety of Tcl_AppendObjToObj(x, x) for bytearrays.bug_2992970dgp2014-01-151-41/+33
| | | | | | | | | Also moves overflow checking to TclAppendBytesToByteArray() and adds the ability to call TABTBA() with bytes==NULL, for appending unspecified bytes. That is, the string grows, but the new bytes are of undetermined value. Like Tcl_NewByteArrayObj(NULL, length) this option is useful for manipulating buffers. The TABTBA growth algorithm is also enhanced a bit, copying over a fuller implementation from GrowStringBuffer() in tclStringObj.c
