y2038: Convert cnd_timedwait to support 64 bit time The cnd_timedwait function has been converted to support 64 bit time. It was also necessary to provide Linux specific copy of it to avoid problems on i686-gnu (i.e. HURD) port, which is not providing pthread_cond_timedwait() supporting 64 bit time. Moreover, a linux specific copy of thrd_priv.h header file has been added as well. The cnd_timedwait is a wrapper on POSIX threads to provide C11 standard threads interface. It directly calls __pthread_cond_timedwait64(). Build tests: ./src/scripts/build-many-glibcs.py glibcs Reviewed-by: Alistair Francis <alistair.francis@wdc.com>

/* Internal C11 threads definitions - linux version
Update copyright dates with scripts/update-copyrights I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines
