* ext/socket/ancdata.c: Check buffer full and ignore MSG_TRUNC flag.

2015-11-19T13:49:58+00:00

  buffer fullness is more robust to detect the message is too big for
  the buffer.
  AIX 7.1 recvmsg doesn't set MSG_TRUNC for rflags when MSG_PEEK is
  given.

* ext/socket/lib/socket.rb (Socket.accept_loop): avoid exceptions
  (Socket.udp_server_recv): ditto

Exceptions for common "errors" make debug output noisy and
allocations+backtrace generation hurt performance.
