[PATCH v4 02/11] Signed-off-by: Karim Taha <address@hidden>

[Karim Taha]

From: Stacey Son <sson@FreeBSD.org>

Add the socket conversion related flags and structs.

Add the relevant definitions of struct target_sockaddr and struct
target_ip_mreq and the related flags, to be used in
bsd-user/bsd-socket.c for the socket conversion functions:
target_to_host_sockaddr, host_to_target_sockaddr, target_to_host_ip_mreq
