Fix logic for saving the snapshot file argument. getopt()
is called at least once after snapshot option is parsed and
getopt() will erase the optarg value when exiting the while
loop. Without this patch, argument is always NULL and snapshot
cannot be taken.

Activated by '-r' option. Useful for intermediate log
processing when the output is used as an input for another
tool. No headers, tokens separated by single spaces,
component ids concatenated with component name to
still produce a single token if present.

On some systems the DSP has no DMA interface to the host and is
using a serial port for sending its trace. This patch adds a "-u"
argument to specify a baudrate, that should be used with the serial
interface. The implementation takes care of spurious bytes,
sometimes seen in the beginning of the trace, produced by the port
initialisation by the DSP. The format is fixed to 8N1.

1. Programs shouldn't exit with negative return values, strictly
speaking only EXIT_SUCCESS and EXIT_FAILURE should be used,
however it is also valid to return 0 for success and any number
from 1 to 125 for a failure.
2. Avoid passing complete structs as function parameters where an
additional copy of one isn't needed, use const pointers instead.
3. Remove a left-over unused argument.
