MEDIUM: pattern: The pattern parser no more uses <opaque> and just takes one string.

After the previous patches, the "pat_parse_strcat()" function disappear,
and the "pat_parse_int()" and "pat_parse_dotted_ver()" functions dont
use anymore the "opaque" argument, and take only one string on his
input.

So, after this patch, each pattern parser no longer use the opaque
variable and take only one string as input. This patch change the
prototype of the pattern parsing functions.

Now, the "char **args" is replaced by a "char *arg", the "int *opaque"
is removed and these functions return 1 in succes case, and 0 if fail.
