+ Catch more strtol() failures when using KEYRINGs
+
+ When parsing what should be a UID while resolving a KEYRING ccache name,
+ don't just depend on strtol() to set errno when the residual that we
+ pass to it can't be parsed as a number. In addition to checking errno,
+ pass in and check the value of an "endptr".
