We do allocate amount of memory (void * or char *), and then assign this
buffer to struct iso_primary_descriptor *vd. Make sure we do
allocate enough bytes.
In fact we do allocate enough, but it is good idea to make sure this really
is so.

The cd9660_open() does pass whole path to dirmatch() and we need to
compare only the current path component, not full path.
Additinally, skip over duplicate / (if any) and check if the last component
in the path was meant to be directory (having trailing /). If it is in fact
a file, error out.
Loader does fail to properly match the file name in directory record and
does open file based on prefix match.
For fix, we check the name lengths first.

There are some _write callbacks left only returning EROFS, replace them
by null_write. return EROFS from null_write().
