[Crash-utility] [ANNOUNCE] crash gcore command, version 1.6.0 is released

[d.hatayama at fujitsu.com]

This is the release of crash gcore command, version 1.6.0.

This release includes the following 1 new feature and 2 bug fixes.

This is tested on the latest kernels on Fedora 33, RHEL8, RHEL7 and
RHEL6 on x86_64.

Note that ZRAM support is not included in this release because some
patch set is still needed in crash utility.

Hagio-san, could you update the description of crash gcore command
at https://crash-utility.github.io/extensions.html?

- Fix failure of collecting vDSO mapping if compat vDSO is disabled
  due to wrongly designed condition for compat tasks that tries to
  determine vDSO mapping based on VDSO_HIGH_BASE. Without this patch,
  vDSO mapping page is not collected for tasks running in 32-bit
  compat mode and thus displaying backtrace by gdb's bt command for
  the tasks could be incomplete.

- Fix failure of invalid structure member offset with the message
  "gcore: invalid structure member offset:
  thread_struct_io_bitmap_max" due to change of kernel data structure
  for io bitmap by the commit <577d5cd7e585> ("x86/ioperm: Move
  iobitmap data into a struct").
