The signal handler for SIGINT/TERM/QUIT and, importantly, SIGPIPE tries
to write an informational message to stderr. When however stderr is
redirected to a closed pipe, this will cause (another) SIGPIPE, and in
turn the signal handler will get called again, and again and again.
Since we intend to exit rtl_fm anyways, we can just ignore this signal.
Fix failures with some GCC versions:
/usr/src/packages/BUILD/src/rtl_tcp.c:90:24: error: initializer element is not constant
static int llbuf_num = DEFAULT_MAX_NUM_BUFFERS;
Fixes: 641c22 ("rtl_tcp: Extracted some constants out of printf strings")

Older versions of GCC will complain that it can be used
uninitialized - which is not the case, but it breaks our Jenkins
build as we build with -Werror.
I've prepared this patch in response to Debian bug #870804https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=870804
It passes the text from the -a and -p options through
getaddrinfo() and uses the first result that has a valid
socket with a successful bind.
While not a complete bind to all possible valid names, it
does appear to address the use case of the bug submitter
without completely changing the program flow.
So far we had 32 * 256KB which was a bit overkill,
15 are more than enough.
15 was chosen instead of 16 because at least on Linux
there seems to be a system-wide limit of 63 transfers
(when they are 256KB large), so 4 dongles can be used
on a single machine without lowering the default transfer
number.
