mov: Export geotag metadata fields

The '?xyz' form is used by android devices (and according to apple
mailing list archives, also by older iOS devices). The 'loci' field
(defined in 3GPP 26.244) is used by recent iOS devices.

Even though the loci field can contain an altitude, it was plain
0 in my sample. Just export longitude and latitude, in a string
format matching the one used by the '?xyz' metadata field.

libfdk-aac: Relicense the library wrappers to the ISC license

This reduces the number of different licenses used within libav,
and is preferrable since it has less ambiguous wordings than
the BSD license with respect to the duties of the user of the code.

Fraunhofer have now indicated that they're allowed to contribute
code under this license as well.

wma lossless: reuse scalarproduct_and_madd_int16

This is done by padding the coefficient buffer with 0s, because the order
may be only a multiple of 4, and the DSP function requires batches of 8.

However, no sample with such a case was found, so request one if it uses
that kind of order.

Approximate relative speedup depending on instruction set:
plain C: -6%
mmxext:  51%
sse2:    54%
