* generic/tclObj.c: Re-ordered error detection code so all values
with trailing garbage receive a "not an integer" message instead of an "integer too large" message. Removed inactive code meant to deal with strtoul* routines that fail to parse leading signs. All of them do, and if any are detected that do not, the correct fix is replacement with compat/strtoul*.c, not a lot of special care by the callers.
