Added possibility to analyze 4 blocks at once in SBC encoder

This change is needed for SIMD optimizations which will follow
shortly. And even for non-SIMD capable platforms it still may
be useful to have possibility to merge several analyzing functions
together into one for better code scheduling or reusing loaded
constants. Also analysis filter functions are now called using
function pointers, which allows the default implementation to be
overrided at runtime (with high precision variant or MMX/SSE2/NEON
optimized code).
