Bug Description

If an IP/ROHC client (resp. server) cuts the TCP control connnection in an abrupt way during the negotiation of tunnel parameters, then the process of the IP/ROHC server (resp. client) may stop.

This is due to a send()/recv()/select() syscall raising an unhandled SIGPIPE in such a case. Correction: ignore SIGPIPE (the syscalls will return the EPIPE error code instead).
