[PATCH] AX25 rose_call - replacing carriage return by newlines

I have been using intensively rose_call application (part of 
ax25tools/user_call library) while debugging rose connect issue.

However once connected rose_call displays remote message without 
linefeed. Consequently it is impossible to read messages.

For example calling local node :

# rose_call rose0 f6bvp f6bvp-4 2080175524
Connecting to f6bvp-4 @ 2080175524 ...

*** Connected

F6BVP-4 (Commands = ?) : Aug  5 2022) for LINUX (help = h)


Then issuing command P to the connected local node, all answer
lines are superimposed.

F6BVP-4 (Commands = ?) : Switch Port


Now with the proposed patch is the complete info displayed:

# ./rose_call rose0 f6bvp f6bvp-4 2080175524

Connecting to f6bvp-4 @ 2080175524 ...

*** Connected

User call : F6BVP-0

Welcome to the last release of Fpac!

This file is fpac.hello and is displayed when

a user connects to the node.



FPAC-Node v 4.1.3 (built Aug  5 2022) for LINUX (help = h)

F6BVP-4 (Commands = ?) :


In file rose_call.c carriage returns are also replaced by newlines
in order to let error messages to be correctly displayed.
