The timestamps for all the buffered frames are scaled against
AV_TIME_BASE_Q, and need to be scaled back to AV_TIME_BASE_Q when they
are extracted from the filterchain.

The decoder is just a wrapper around the AAC decoder.

Use avctx in all called functions. This allows passing a NULL AACContext
for LATM since the AACContext is only used in output_configure() which
is skipped for LATM parsing.

aac_decode_frame() remains as AVPacket handling a wrapper. The actual
decoding function takes a GetBitContext as input and will be used be the
AAC LATM decoder to avoid copying the unaligned AAC bitstream.

This will be used by the latm decoder to avoid AACContext changes during
audio specific config parsing.

The user is requested to specify "-f image2" in place of "-f pgmyuv"
for reading/writing PGMYUV files, as for the other image formats.

prefix does not contain other characters which may belong to an
identifier.
This allows to distinguish for example to have different constants
with the same prefix (e.g. "foo" and "foobar").

The 3GPP spec uses the following calculation for high spreading:
thr'_spr = max(thr_scaled, s_h(n) * thr_scaled(n-1))
where, n is defined as the current band, and s_h() is defined as "[...] the
distance of adjacent bands in Bark and a constant slope that is 15 dB/Bark
[...]". This is a little ambiguous as you would assume you want the Bark
width of the previous band for this calculation. However, this assumption
appears to be incorrect, and you really want the Bark width of the current
band. Coincidentally this is exactly what the spec calls for! =P
This noticeably improves Tom's Diner at low bitrates (I tested at 64kbps,
with mid/side disabled).

These blocks depended on the compiler keeping xmm registers untouched between
them.
