Update asiolink for boost 1.87

[q66]

i'm going through boost 1.87 update in chimera linux and kea was one of the things failing to build due to removal of deprecated api from asio, so here are fixes

If it works it should be better to include the asiolink/io_service.h file in iface_mgr.cc.

BTW I am afraid that some unit test and hook file need update too.

hm, i'm not sure what that means? oh, nevermind, the header contains a typedef

Integrated into Kea gitlab issue 3696 which should be very likely in the next release 2.7.6 at the end of January 2025.

@q66, would you like to be commended in the AUTHORS file for this contribution? And if so, should it be under name q66?

[fxdupont]

Or in the ChangeLog entry? In anycase your name is needed...

[q66]

i don't really mind either way but if you do, yes that's fine

Not really. q66 would be probably the shortest attribution and most cryptic so far, but I will do.

Thanks for the patch!
