libcares: updated to 1.16.1

c-ares version 1.16.1

Security:
* Prevent possible use-after-free and double-free in ares_getaddrinfo() if \ 
ares_destroy() is called prior to ares_getaddrinfo() completing. Reported by \ 
Jann Horn at Google Project Zero.

Changes:
* Allow TXT records on CHAOS qclass. Used for retriving things like \ 
version.bind, version.server, authoris.bind, hostname.bind, and id.server.

Bug fixes:
* Fix Windows Unicode incompatibilities with ares_getaddrinfo()
* Silence false cast-align compiler warnings due to valid casts of struct \ 
sockaddr to struct sockaddr_in and struct sockaddr_in6.
* MacOS should use libresolv for retrieving DNS servers, like iOS
* CMake build system should populate the INCLUDE_DIRECTORIES property of \ 
installed targets
* Correct macros in use for the ares_getaddrinfo.3 man page
