Details:

Would it be possible to add an socket offset to the socket API so the socket
number is increased with the defined number?

Something like:
LWIP_SOCKET_OFFSET==n: Increases the file descriptor number created by LwIP
with n. This can be usefull when there are multiple API's which create file
descriptors. When they all start with a different offset and you won't make
them overlap you can re implement
read/write/close/ioctl/fnctl to send the requested action to the right
library.

The only problem is that select would need a quite expensive wrapper anyway
because you would need to split the fd_set's to the appropriate library's.

I provided a patch against v1.4.0.
