- update to 2.5.4:
* fix prompting for password on windows console if stderr redirection
is in use - this breaks 2.5.x on Win11/ARM, and might also break
on Win11/adm64 when released.
* fix setting MAC address on TAP adapters (--lladdr) to use sitnl
(was overlooked, and still used "ifconfig" calls)
* various improvements for man page building (rst2man/rst2html etc)
* minor bugfix with IN6_IS_ADDR_UNSPECIFIED() use (breaks build on
at least one platform strictly checking this)
* fix minor memory leak under certain conditions in add_route() and
add_route_ipv6()
* documentation improvements
* copyright updates where needed
* better error reporting when win32 console access fails
