-c-ares version 1.22.1

-This is a bugfix release.
+This is a feature and bugfix release.
+
+Features:
+ o Introduce optional (but on by default) thread-safety for the c-ares
+   library.  This has no API nor ABI implications. [2]
+ o resolv.conf in modern systems uses attempts and timeouts options instead
+   of the old retrans and retry options. [6]
+ o Query caching support based on TTL of responses. Can be enabled via
+   ares_init_options() with ARES_OPT_QUERY_CACHE. [12]
 
 Bug Fixes:
- o Fix /etc/hosts processing performance with all entries using same IP
+ o ares_init_options() for ARES_OPT_UDP_PORT and ARES_OPT_TCP_PORT accept the
-   address. Large hosts files using the same IP address for all entries
+   port in host byte order, but it was reading it as network byte order.
-   could use exponential time. [1]
+   Regression introduced in 1.20.0. [1]
- o Fix typos in manpages [2]
+ o ares_init_options() for ARES_FLAG_NOSEARCH was not being honored for
- o Fix OpenWatcom building [3]
+   ares_getaddrinfo() or ares_gethostbyname().  Regression introduced in
+   1.16.0. [3]
+ o Autotools MacOS and iOS version check was failing [4]
+ o Environment variables passed to c-ares are meant to be an override for
+   system configuration. Regression introduced in 1.22.0. [5]
+ o Spelling fixes as detected by codespell. [7]
+ o The timeout returned by ares_timeout() was truncated to milliseconds but
+   validated to microseconds which could cause a user to attempt to process
+   timeouts prior to the timeout actually expiring. [8]
+ o CMake was not honoring CXXFLAGS passed in via the environment which could
+   cause compile and link errors with distribution hardening flags during
+   packaging. [9]
+ o Fix Windows UWP and Cygwin compilation. [10]
+ o ares_set_servers_*() for legacy reasons needs to accept an empty server list
+   and zero out all servers. This results in an inoperable channel and thus is
+   only used in simulation testing, but we don't want to break users.
+   Regression introduced in 1.21.0. [11]
