b237248e29 adx: calculate correct LPC coeffs 
Instead of using fixed coefficients, the correct way is to calculate the
coefficients using the highpass cutoff frequency from the ADX stream header
and the sample rate.

f7f892e4d5 svq1enc: fix signed multiplication overflow 
This multiplication can overflow the signed range but not the
unsigned.  After right-shifting it will thus fit in the signed

cc276c85d1 Make channel layout masks unsigned 
It makes more sense for a bit mask to use an unsigned type.
The change should be source and binary compatible on all
supported systems, hence micro version bump.

Fixes a few invalid shifts.

05d1e45d1f wma: initialize prev_block_len_bits, next_block_len_bits, and block_len_bits. 
The initial values are not checked against the number of block sizes.
Initializing them to frame_len_bits will result in a block size index of 0
in these cases instead of something that might be out-of-range.

8ee2b4672f ARM: add explicit .arch and .fpu directives to asm.S 
This prevents build errors when compiler and assembler default
targets differ.  Ideally each file would declare the highest
level it requires.  This is however not easily possible as it
complicates assembling pre-armv6t2 code in Thumb-2 mode.

HAVE_NEON is used as indicator for ARMv7-A since no other
symbol exists for this and NEON is only available in this
variant.
