This patch, relative to a tree with <https://sourceware.org/ml/libc-alpha/2017-11/msg00797.html> (pending review) applied, obsoletes p_secstodate, making the underlying function __p_secstodate into a compat symbol not available for new binaries or ports. The calls in ns_print.c (part of incomplete handling of TKEY) are changed to use %lu to print times instead of trying to pretty-print the times any more. Tested for x86_64. * resolv/res_debug.c (p_secstodate): Condition definition on [SHLIB_COMPAT (libresolv, GLIBC_2_0, GLIBC_2_27)]. Define directly as __p_secstodate, and as a compat symbol. Do not use libresolv_hidden_def. * resolv/resolv.h (p_secstodate): Remove macro and function declaration. * resolv/ns_print.c (ns_sprintrrf): Print times with %lu, not using p_secstodate. * include/resolv.h (__p_secstodate): Do not use libresolv_hidden_proto. * resolv/Makefile (tests): Move tst-p_secstodate to .... (tests-internal): ... here. * resolv/tst-p_secstodate.c: Include <shlib-compat.h>. Condition all contents on [TEST_COMPAT (libresolv, GLIBC_2_0, GLIBC_2_27)] and declare and use __p_secstodate and use compat_symbol_reference in that case. [!TEST_COMPAT (libresolv, GLIBC_2_0, GLIBC_2_27)] (do_test): Add implementation returning 77.
