Use of -funroll-loops option to improve SBC encoder performance
Added the use of -funroll-loops gcc option for SBC. Also in
order to gain better effect, 'sbc_pack_frame' function
body moved to an inline function, which gets instantiated
for 4 different subbands/channels combinations. So that
'frame_subbands' and 'frame_channels' arguments become compile
time constants and can be better optimized by the compiler.
