Accumulate all block entries in format_blocks

[Kuroneer]

Unless I'm mistaken (dealing with carriers in Erlang is not that easy), in recon_alloc, the format_blocks' Acc should be used when computing the total size and block count for an allocator. Otherwise, you get things like

  {mbcs,[{blocks,77,77,77},
          {blocks_size,7584,7584,7584},
          {foreign_blocks,[{ets_alloc,[{count,45,45,49},
                                       {size,45056,45056,46080}]},
                           {eheap_alloc,[{count,4,5,71},{size,243464,246480,246480}]},
                           {std_alloc,[{count,77,77,77},{size,7584,7584,7584}]}]},
          {raw_blocks,[{binary_alloc,[{count,1714,1715,1715},
                                      {size,1804080,1882840,1882840}]},
                       {ets_alloc,[{count,45,45,49},{size,45056,45056,46080}]},
                       {eheap_alloc,[{count,4,5,71},{size,243464,246480,246480}]},
                       {std_alloc,[{count,77,77,77},{size,7584,7584,7584}]}]},

when calling recon_alloc:allocators/0 (and recon_alloc:fragmentation/1)

Yep that sounds right and I forgot about the accumulation, good catch.

Hi, sorry to come in here many months later, but it'd be nice to have a release with this fix (without it the output of :recon_alloc.memory(:used) can be way off in some cases (we observed 95%+ underreporting of used memory)).

[ferd]

Done, sorry for having forgotten.
