[Crash-utility] [ANNOUNCE] crash gcore command, version 1.3.0-rc is released

This is the release of crash gcore command, version 1.3.0-rc.

The version 1.3.0 is going to newly add ARM64 support, and the
purpose of this rc version release is for verification by other
architecture maintainers. Please give me a verfication result as a
reply to this mail.

The remaining changes are all bugfixes.


 - Add ARM64 support. In addition to native ARM64 build, like crash
   utility, we can build x86_64 executable of crash gcore command for
   ARM64 crash dump by make target=ARM64, just like crash utility.

 - Fix a bug that registers in NT_PRSTATUS note information is
   broken. This had been since v1.2.2 when O(1) note informaiton
   collection was added. Without this fix, we can never get reliable
   register values for failure analysis.

 - Fix a bug that NT_386_IOPERM note information is not collected. So
   far, ioperm_get() had always returned 1. As a result, NT_386_IOPERM
   note information had never been not included in a generated core
   file even if it is available for a given task on a given crash

 - Add new member offset initialization for struct
   nsproxy::pid_ns_for_children. In upstream, the following patch
   renamed struct nsproxy::pid_ns into struct

        Rename nsproxy.pid_ns to nsproxy.pid_ns_for_children

        nsproxy.pid_ns is *not* the task's pid namespace.  The name
should clarify

        This makes it more obvious that setns on a pid namespace is weird --
        it won't change the pid namespace shown in procfs.

   Without this fix, gcore exited abnormally at its initialization
   part and so core file is never generated.

 - Fix a bug that a wrong way of checking return value of
   fopen(). fopen() returns NULL in case of error, but gcore had seen
   it as returning a minus integer. As a result, gcore continues
   execution after the check even in case of error and then exits
   abnormally at the first call of fwrite() with the broken file
   pointer gcore failed to open.

   From users' viewpoint, we face this bug when trying to overwrite an
   existing corefile with more priviledged permission and resulting in
   EPERM failure.
