The declaration of time_t is in flux based on it's overflow in Year 2038, so declare it uniformly based on System.Parameter.time_t_bits to ease this transition and also enable VxWorks targets which allow it to be parameterized, to be rebuilt more easily by one source change.
Two changes of note:
s-linux__x32.ads also changes the size of suseconds_t and the field
tv_nsec in timespec to be 64 bits. Since it's a one of, it's not
handled via System.Parameters.
s-os_lib.ads contains a subtype time_t formerly of Long_Integer, changed
to Long_Long_Integer. This declaration is not used in the runtime, but
is available to application code via the renaming g-os_lib.ads. This
may cause some customer code to not compile, but is easily fixed by a
source code change. The alternative is to have two versions of
s-os_lib.ads, identical except for this subtype declaration.
