[Crash-utility] [ANNOUNCE] crash gcore command, version 1.5.1 is released

This is the release of crash gcore command, version 1.5.1. This release includes the following 2 bug fixes. ChangeLog: - Fix the invalid structure member failure of thread_struct_fpsimd_state caused by the commit 65896545b69ffaac947c12e11d3dcc57fd1fb772 merged at v4.17-rc2 ("arm64: uaccess: Fix omissions from usercopy whitelist") that changed struct thread_struct. Without this fix, gcore command fails with the following error message: crash> gcore 2190 gcore: invalid structure member offset: thread_struct_fpsimd_state FILE: libgcore/gcore_arm64.c LINE: 46 FUNCTION: fpr_get() [./crash] error trace: ffff81c44c8c => ffff81c48fb8 => 51afd8 => 51af50 51af50: OFFSET_verify.part.28+72 51afd8: store_module_kallsyms_v2.part.29+0 gcore: invalid structure member offset: thread_struct_fpsimd_state FILE: libgcore/gcore_arm64.c LINE: 46 FUNCTION: fpr_get() Failed. (anderson(a)redhat.com) - Fix the invalid structure size failure of pid_link on v4.19 and newer kernel introduced by the commit 2c4704756cab ("pids: Move the pgrp and session pid pointers from task_struct to signal_struct") that removed struct pid_link array from task_struct and added struct pid array into signal_struct. Without this fix, gcore command fails with the following error message: gcore: invalid structure size: pid_link FILE: libgcore/gcore_coredump_table.c LINE: 423 FUNCTION: pid_alive() [./crash] error trace: 7f4a7a6762b8 => 7f4a7a676e0f => 53b391 => 53b316 53b316: SIZE_verify.part.31+70 53b391: SIZE_verify+49 gcore: invalid structure size: pid_link FILE: libgcore/gcore_coredump_table.c LINE: 423 FUNCTION: pid_alive() Failed.
