Log:
[Ada] Make Max_Sensible_Delay uniform across all Posix targets

For instance: 6 months where Duration is 64bits.  Heretofore LynxOS was unique
in having an approximately 12 days max delay. By experimentation the actual
maximum was determined and all relevant delay and sleep procedures rewritten to
incrementally wait if necessary.
