Harald Welte 05cc7f6531 ringbuffer: Don't print/TRAC from ringbuffer ...

In commit eac1bec428 we start to use the
ringbuffer inside the console printing code.  As a result, we must not
use TRACE_*() or printf() from within ringbuffer.c code to avoid
infinite recursion.

Instead, let rbuf_write() return a negative return value in case the
ring buffer overflows.  This way, the callers (outside the
console/stdout code) can print an error message themselves.
