This fixes ugliness when configure outputs its (empty) results on HPUX

and use in scale_coefficients() for the floating-point AC-3 encoder.

This updates the seek test reference to match de11ee90.  Before this
change, most of the seeks requested positions before the supposed
start of the file (the preroll time), resulting in the first packet
being returned.  With the preroll subtracted, some of these seeks
will land within the file and some beyond the end, thus returning
a different set of packets.

Add an APIchanges entry for the av_pkt_dump2 and av_pkt_dump_log2
functions, and a changelog entry for the apple http live streaming
protocol handler.

Since neither of them got a minor bump at commit time, but were
applied before the jv demuxer, they all can be considered added
in this minor version.

Correct bad indentation in aaccoder
Clarify and correct comments in 3GPP psymodel, other cosmetics.

3GPP:
Remove ffac from and move min_snr out of AacPsyBand.
Rearrange AacPsyCoeffs to make it easier to implement energy spreading.
Rename the band[] array to bands[]
Copy energies and thresholds at the end of analysis.

LAME:
Use a loop instead of an if chain in LAME windowing.

This allows them to share code which can be optimised for various

update mailing list references and irc channels in configure

The two functions are identical, no point in duplicating code here.

This fixes invalid reads/writes with this sample:

If the function is not inlined, an immmediate cannot be used for the
shift parameter, so the %cl register must be used instead in that case.

This fixes compilation for x86-32 using gcc with --disable-optimizations.

The 1-arg imul instruction cannot take an immediate argument, only a register
or memory argument.

This fixes unexpected name collisions that were occurring with variables
declared within the macros.
It also fixes the fate-acodec-ac3_fixed regression test on x86-32.
