Hello team!

c-ares version 1.22.0

This is a feature release with some significant internal changes.

Features:
  o ares_reinit() is now implemented to re-read any system configuration and
    immediately apply to an existing ares channel [2]
  o The adig command line program has been rewritten and its format now more
    closely matches that of BIND's dig utility [3]
  o The new DNS message parser and writer functions have now been made public [4]
  o RFC9460 HTTPS and SVCB records are now supported [5]
  o RFC6698 TLSA records are now supported [6]
  o The server list is now internally dynamic and can be changed without
    impacting existing queries [10]
  o Hosts file processing is now cached until the file is detected to be changed
    to speed up repetitive lookups of large hosts files [11]

Changes:
  o Internally all DNS messages are now written using the new DNS writing
    functions [7]
  o EDNS is now enabled by default [8]
  o Internal cleanups in function prototypes [9]

Bug Fixes:
  o Randomize retry penalties to prevent thundering herd issues when dns
    servers throttle requests [1]
  o Fix Windows build error for missing if_indextoname() [10]
