Feature Request: Allow pseudo terminal option (-p) to specify symlink name

[radar27]

Greetings,

In some cases, multiple instances of Direwolf are running, but need support for for a Virtual KISS TNC as provided by the -p startup option. By default this is always linked to /tmp/kisstnc, creating a race condition on the symlink by whichever instance starts last.

Would it be possible for -p to accept an optional argument to specify the name of the target symlink? Something like:

direwolf -c direwolf-40m.conf -p /tmp/kiss40m
direwolf -c direwolf-2m.conf -p /tmp/kiss2m
direwolf -c direwolf-70cm.conf -p /tmp/kiss70cm

From there one could attach the 40m instance via /tmp/kiss40m, the 2m instance via /tmp/kiss2m and the 70cm instance via /tmp/kiss70cm. If the -p option is specified with no argument, it continue to default to /tmp/kisstnc as to not disrupt backwards compatibility.

73!

This seems like a useful enhancement to me for those who wish to use the native Linux AX.25 stack with one radio per Direwolf instance

Please can we add this? I'd almost rather set up the devnames with 'socat' than let DW do it and if we can send an arg to '-p' that would solve this. Bonus for allowing more than one invokation on the CLI for '-p device-name' for those running dual stack things in linux like ax25 and JNOS or something else. Since we cant have two things consume a psuedo serial port that should make sense.
