Block allocation algorithm

val allocate_trivial_strategy : Nn_blockmap.blockmap_t list ->
       Nn_alloc_types.transacted_datastores ->
       Nn_blockmap.owner -> int -> int64 -> int -> Nn_blocklist.blocklist

allocate_trivial_strategy bmaps td owner repl index number: Allocates blocks for the index range index to index+number-1. The replication factor is repl. The blocks are allocated in the passed blockmaps bmaps, and will be assigned to owner. Tickets are generated for the transaction identified by td.

This is the "trivial" algorithm. It iterates over the index range and tries to allocate each block separately, without taking advantage of the range. This algorithm should not be used anymore; it is kept in the code base purely for documentation purposes.
