Commit Message

Michael Tokarev Oct. 5, 2024, 7:07 a.m. UTC 
libslirp introduced new typedef after 4.8.0, slirp_os_socket, which
is defined to SOCKET on windows, which, in turn, is a 64bit number.
qemu uses int, so callback function prorotypes changed.  Introduce
slirp_os_socket locally if SLIRP_INVALID_SOCKET is not defined (this
define has been introduced together wiht slirp_os_socket type), for
libslirp <= 4.8.0, and use it in callback function definitions.
