Tobias Girstmair 142325a93c Fix signal handler from getting stuck in an endless loop 
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.

Steve Markgraf 89f73b183f lib: change default number of transfers to 15 
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.
