y2038: Introduce struct __ntptimeval64 - new internal glibc type
This type is a glibc's "internal" type to get time parameters data from Linux kernel (NTP daemon interface). It stores time in struct __timeval64 rather than struct timeval, which makes it Y2038-proof. Build tests: ./src/scripts/build-many-glibcs.py glibcs Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
