Alexander Motin 002bc3da6a BRT: Increase block size from 4KB to 8KB 
According to my observations, BRT ZAPs are typically compressible
3:1 for data and 2:1 for indirects.  With ashift=12, typical these
days, it means increasing the block sizes to 8KB we may get most
of possible compression, reducing on-disk and in-ARC BRT footprint
in half by the cost of some compression/decompression overhead,
but without real write inflation, only some dirty data increase.

Increase to 32KB similar to DDT could further increase compression
and storage efficiency, but at the cost of write inflation and
much bigger dirty data increase, which we can not properly control
now.  So lets leave this for a time when BRT log gets implemented.
