- Update to version 1.23

Browse Source 
Features:
    Introduce optional (but on by default) thread-safety for the c-ares library. This has no API nor ABI implications.
    resolv.conf in modern systems uses attempts and timeouts options instead of the old retrans and retry options.
    Query caching support based on TTL of responses. Can be enabled via ares_init_options() with ARES_OPT_QUERY_CACHE. 
  Bugfixes:
    ares_init_options() for ARES_OPT_UDP_PORT and ARES_OPT_TCP_PORT accept theport in host byte order, but it was reading it as network byte order. Regression introduced in 1.20.0.
    ares_init_options() for ARES_FLAG_NOSEARCH was not being honored forares_getaddrinfo() or ares_gethostbyname(). Regression introduced in 1.16.0.
    Autotools MacOS and iOS version check was failing
    Environment variables passed to c-ares are meant to be an override for system configuration. Regression introduced in 1.22.0.
    Spelling fixes as detected by codespell.
    The timeout returned by ares_timeout() was truncated to milliseconds butvalidated to microseconds which could cause a user to attempt to process timeouts prior to the timeout actually expiring.
    CMake was not honoring CXXFLAGS passed in via the environment which couldcause compile and link errors with distribution hardening flags during packaging.
    Fix Windows UWP and Cygwin compilation.
    ares_set_servers_*() for legacy reasons needs to accept an empty server listand 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. 
Changes in version 1.22.1
  Bugfixes:
    Fix /etc/hosts processing performance with all entries using same IPaddress. Large hosts files using the same IP address for all entries could use exponential time.
    Fix typos in manpages
    Fix OpenWatcom building 
Changes in version 1.22.0
  Features:
    ares_reinit() is now implemented to re-read any system configuration and immediately apply to an existing ares channel
    The adig command line program has been rewritten and its format now more closely matches that of BIND's dig utility
    The new DNS message parser and writer functions have now been made public
    RFC9460 HTTPS and SVCB records are now supported
    RFC6698 TLSA records are now supported
    The server list is now internally dynamic and can be changed without impacting existing queries
    Hosts file processing is now cached until the file is detected to be changed to speed up repetitive lookups of large hosts files
