[RELEASE] c-ares 1.22.1

[Daniel Stenberg]

Hello!

c-ares version 1.22.1 is here. Get it from https://c-ares.org/

This is a bugfix release.

Bug Fixes:
  o Fix /etc/hosts processing performance with all entries using same IP
    address. Large hosts files using the same IP address for all entries
    could use exponential time. [1]
  o Fix typos in manpages [2]
  o Fix OpenWatcom building [3]
