This commit extends the meta block structure by fields in which we store
pointers to face, edge and corner neighbors.
In the current implementation the boundary update is only done for block
faces, meaning that the corners are not properly updated between the blocks
on different levels. This, of course, can create unexpected problems,
like improper interpolation in the ghost zones, resulting in NaNs there.
The fields for neighbor pointers should allow for a quick access to neighbors
for full, properly done, boundary update.

Update the leaf state and counter nleafs in metablock_set_leaf() and
metablock_unset_leaf() only if they really change the state.

Similarily to dblocks, mblocks should count the number of allocated meta
block which are stored in the meta block list, therefore it should be
updated in append_metablock(), remove_metablock(), insert_metablock_*(),
etc.

The data block counter dblocks shouldn't be update in
allocate_datablock() and deallocate_datablock(), since these subroutines
can be used to allocate temporary data blocks. Instead, the counter
dblocks should count only allocated data blocks which are stored in the
list_data data block list.
Therefore, move the update of dblocks to append_datablock() and
remove_datablock().

We prepare a set of indices for all faces in the block. Those indices
point to edges and corners for each face, and are set one during the
first execution. Then, we simply iterate over faces and call
iterate_over_face() in order to apply subroutine pprocedure to edges and
corners connected to a given face.

Add subroutines to iterate over all block neighbors and check if they
reference to correct meta blocks. The neighbor consistency check is
done after initial mesh generation and each time the mesh has been
updated.

In 2D case, if we update corners using only X-edge neighbors, we get
some rare problems with symmetry. If we additionally use Y-edge
neighbors, to update corners, those problems disappear. This should be
additionally tested for both, 2D and 3D cases.

The job restart with smaller number of processors than the number of
files didn't work well, since all metablocks of all remaining files
where set to the last process before actually reading the corresponding
data blocks. This resulted in a crash in redistribute_blocks() due to
pointer not associated.
The fix lets the meta blocks to be restored with the original process
numbers. While reading files with the indices larger than the index of
the last process, all meta blocks which corresponding data blocks are
stored in the read file, are set to the process number of the reading
process. After reading data blocks from each file, the blocks are
redistributed. However, only data blocks belonging to the active
processes are redistributed.

In this patch we make a general subroutine iterating over all neighbors
iterate_over_neighbors() which takes as arguments a pointer to the block
which neighbors are evaluated and pointer to subroutine which should be
called with each neighbor. So far two such subroutines are used, one to
select the proper refinement flag, and another to select the neighbor
for update.

Those arrays are prepared only at the first execution and then stored in
memory, therefore there is no need to preparing them each time
refine_block() is called. This removes also one 'select which' condition
check.

If we take the whole domain and divide it between blocks of the size
corresponding to the current lever, the field %coords identifies the
position of the current block in the domain.

This patch marks all refined or derefined blocks to be updated. All
their face, edge, and corner neighbors are marked for update as well, in
order to keep the boundary consistency.

Those two subroutines insert a new meta block after or before the block
which is provided by additional pointer.
