In preparation for introducing TLS support to the TCP chardev
backend, convert existing chardev code from using GIOChannel
to QIOChannel. This simplifies the chardev code by removing
most of the OS platform conditional code for dealing with
file descriptor passing.

A variety of places were snprintf()ing into a fixed length
filename buffer. Some of the buffers were stack allocated,
while another was heap allocated with g_malloc(). Switch
them all to heap allocated using g_strdup_printf() avoiding
arbitrary length restrictions.

When defining values for long options, the normal practice is
to start numbering from 256, to avoid overlap with the range
of valid values for short options.
