Found another one. Put 'C' in the long form.

-Z and -O (short form) were not used anywhere in the option processing

't' in shortoption form not used.
Use 'd' in the longform svcd option.

the 'm' option wasn't used anywhere so remove it from the shortform getopt list.
Then for those options which have short forms use their option letter in the
long form processing.

Unused structure definition removed.

Warning error was:
liblavrec.c: In function 'lavrec_hardware_init':

Adding an extra pair of parentheses gets rid of the message (and makes it
clearer what is going on).
