dahdi: Add module parameter to limit number of pseudo channels.
Since there isn't a fixed array to hold all the channels, and also limit
the total number of channels that can be created, we'll add a module
parameter to allow the system administrator to specify the maximum
number of pseudo channels. This is to prevent a potentially
non-privledged process from consuming too much CPU (since all pseudos
are checked each "tick" for conferencing) and kernel memory.
By default the number of pseudo channels is limited to 512. Change the
default limit with:
]# modprobe dahdi max_pseudo_channels=<new limit>
or at runtime with:
]# echo <new limit> > /sys/module/dahdi/parameters/max_psuedo_channels
