## Summary

cpukit/libmisc: Remove the dead range checks

The string to integer template checked the range of the value in
every instantiation.  Six of the seven integer instantiations use a
conversion method whose type is not wider than the type of the value.
For those the two comparisons were constant and the code behind them
was dead.  Coverity reported this as CID 1700407 to CID 1700418.

Emit the range check only where the type of the conversion method is
wider than the type of the value.  Every instantiation which sets
STRING_TO_RESULT_TYPE gives the maximum of that type in
STRING_TO_RESULT_MAX.  The template compares the two maxima.  An
undefined macro drops the check without a diagnostic, so a missing
STRING_TO_RESULT_MAX is an error.

Behaviour is unchanged.  Where the two types have the same width, the
conversion method sets ERANGE.  The template already turns ERANGE into
RTEMS_INVALID_NUMBER.

Update #5708.
