ac may be NULL and then accessing ac->avctx results in a segmentation fault.

warning: incompatible
      pointer types assigning to 'me_cmp_func' (aka 'int (*)(struct

Fix a rather lengthy initialization warning from clang.

nlvl_to and nlvl_from can be set to 1 if both alias and target files
are in the same directory, so actually check the first character of the
string. We can do this because MacOS filepaths (alis type 2) are always
converted to UNIX filepaths (alis type 18).

Absolute paths can be stored in alis type 2 and 18 according to my research:
the first is the canonical MacOS filepath, with path level separated by
colons, and the volume name within the filepath, while the second should be the
absolute filesystem path from the mount point.

Add some bounds checking to CLLC; reduce HQX variable scoping,
add an error message.

They belong to the same family of codecs.
