avutil/imgutils: remove special case for aligning the palette

This was suggested by wm4 and stefano.
After this patch using align=1 the size used by various functions would not
contain padding, while the palette would be aligned at align>1

This patch makes it required to use align>=4 if the palette is to be accessed
as uint32

aacenc: make a better estimate for the audio bitrate if not provided

Takes into account whether there's pairing and if there's an LFE channel.
An SCE has more bits than CPE/2 since IS and M/S save quite a lot of bits
when channels are paired. And most of the SCEs we have are in surround
layouts which map it to the center channel, which usually carries all of
the dialogue and compression artifacts there are easily audiable.

Also refactors the init function a little bit and labels some parts of it.
