warning: incompatible
      pointer types assigning to 'me_cmp_func' (aka 'int (*)(struct
      MpegEncContext *, uint8_t *, uint8_t *, ptrdiff_t, int)') from 'int
      (MpegEncContext *, uint8_t *, uint8_t *, int, int)'

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.

In preparation for multithreaded decoding.

This applies to every library where performance is not critical.

And deprecate av_dlog macro.

The AVSC_API changes in the new headers mean that the 2.6 alphas
are just as incompatible as 2.5 is.

In order to safely exit when the user tries to use AviSynth 2.5, the
continue_on_fail value for 2.6's functions need to be set to 1.
Otherwise, the library loader fails before the 'upgrade to 2.6'
log message appears.

They seem to sometimes trigger with old AVI files. They are just
confusing, do not help anyone, and use sloppy language.

This is optional, but ensures that linking with -Wl,--as-needed does not
drop the library containing the MMAL VC driver. The driver normally
"registers" itself in the library constructor, but since no symbols are
explicitly referenced, the linker could remove it with --as-needed
enabled.
