The arguments passed after the set command are not handled properly,
leading to segfaults or inability to set controls
Example with control 0 which is Headset Volume on my NUC:
before fix
$ ./tinymix set 0
Segmentation fault
$ ./tinymix set 0 10
Segmentation fault
$ ./tinymix set 0 10 20
Error: 3 values given, but control only takes 2
After correction
$ ./tinymix set 0
no value(s) specified
$ ./tinymix set 0 10
$ ./tinymix set 0 10 10
$ ./tinymix set 0 10 10 10
Error: 3 values given, but control only takes 2

The TLV byte controls expect a TLV header as well. Check for TLV
access and add TLV header size before invoking mixer API.

hundreds of paths on the audio side of this chip.
There was a recent change whereby tinymix will ALWAYS prints the routes/paths
for the different ports on ALSA. I consider this to be a regression. It
really should only be printed if asked.
In addition, I've modified tinymix to more closely conform to the following:

Lastly, I removed a redundant errno.h..
