socket_listen and socket_connect do not allow custom socket option.
This would be inconvenient if the caller wants a non-blocking socket,
or wants to set TCP_NODELAY or other options.
This series of patches add specific config structures, QemuSocketConfig,
which contains QemuSocketOption. All the QemuSocketOption are formed
as a linked list.
The caller is reponsible for setting up the config structure. Passing
an NULL pointer would use the original socket_listen/socket_connect,
so existing functions are not affected.
Note that the caller needs to check errno after socket_connect when
using a non-blocking socket. It does not have to in other cases.
