aac46e088d aacsbr: move some simdable loops to function pointers 
This prepares for assembly optimisations by moving the most
time-consuming loops to functions called through pointers
in a new context.

9a7dc618c5 libavcodec: Don't crash in avcodec_encode_audio if time_base isn't set 
Earlier, calling avcodec_encode_audio worked fine even if time_base
wasn't set. Now it crashes due to trying to scale the output pts to
the codec context time base. This affects e.g. VLC.

If no time_base is set for audio codecs, set it to the sample
rate.

it's a bug nevertheless. Fixes SA10116.vc1 on my 64-bit

d78bb1a4b2 wma: Clip WMA1 and WMA2 frame length to 11 bits. 
The MDCT buffers in the decoder are only sized for up to 11 bits. The
reverse engineered documentation for WMA1/2 headers say that that for
all samplerates above 32kHz 11 bits are used. 12 and 13 bit support
were added for WMAPro. I was unable to make any Microsoft tools generate
a test file at a samplerate above 48kHz.
