Pau Espin Pedrol 4949df257e Proper shutdown on SIGHUP
If a process exits and has a controlling terminal, everything under
it gets a SIGHUP by the kernel. That's the case for instance when
running a srsUE over ssh with some specific parameters. As a result,
when the ssh client is killed, SIGHUP is sent to srsUE, which will be
killed immediatelly without proper release, which means in turn that log
buffers are not flushed.
Let's do proper shutdown when SIGHUP is received so that everyone can
get log files.

Pau Espin Pedrol 64de92183b epc: Drop signal(SIGKILL) calls
SIGKILL cannot be intercepted by apps, so it's useless adding a signal
handler for them. I'm pretty sure the signal() function is erroring in
this scenarios. From signal() man page:
"The signals SIGKILL and SIGSTOP cannot be caught or ignored."
