51497fe60d BOUNDARIES: Add subroutine to handle exchange block arrays. 
Two new arrays barray and bcount are allocated during the module
initialization and deallocated during the module finalization.

Those two arrays are used to store information about neighbors which
lay on different processes and need some boundary data to exchange.

Subroutines prepare_exchange_array() and release_exchange_array() are
responsinble for initialization of barray and bcount and for
deallocation all array elements, respectively.

Subroutine append_exchange_block() helps to append a new block pairs to
the exchange array.

53719482ed BOUNDARIES: Fix memory leaking in boundary_fluxes(). 
When blocks belong to the same process which is not the current one, the
block exchange structure is unnecessary allocated, and is not
deallocated after the block exchange.

Fix this by allocating block exchange structures only when the block and
its neighbor processes are different.
