Release mdadm-4.6

Hi all

I'm glad to announce mdadm-4.5. It is published to both remotes
(github and kernel.org). Here are some highlights from CHANGELOG.md.

# Release [mdadm-4.6](https://git.kernel.org/pub/scm/utils/mdadm/mdadm.git/log/?h=mdadm-4.6)

Features:
- Add support for new lockless bitmap from Yu Kuai
- Add "PROBING ddf_extended" option in mdadm.conf from Martin Wilck
- Add --detail to usage in ReadMe from Brian Matheson

Fixes:
- Fix uuid endianness mismatch issue in sysfs_rules_apply() from Abirami0904
- Fix mdcheck: don't stop mdcheck_continue.timer from Martin Wilck
- Deal with hot-unplugged devices in platform-intel from Jean Delvare
- Detect corosync and libdlm via pkg-config in Makefile from Maxin John
- Fix UEFI backward compatibility for RAID10D4 in imsm from Blazej Kucman

There are some important issues which led to boot failure. These issues
have been fixed recently. It's better to make a new release. So users
can choose a version without these problems.
https://github.com/md-raid-utilities/mdadm/issues/249 has the details.

Best Regards
Xiao
