Replace libsparsehash with sparsehash-c11
...
- use sparsehash-c11 over libsparsehash
- fix typos in find_sparsehash and users of the vars (s/SPARCE/SPARSE/)
- drop libsparsehash-dev from docker images (but keep for unbunlded build)
- use ::google over GOOGLE_NAMESPACE

Use internal iteration over hash tables in Aggregator.
...
For compound hash tables such as the future StringHashMap, an
iterator-based API might be inefficient for iterating over a table or
for merging two tables, because:
1) the key has to be converted to a general format from a from a
component-specific format, which may differ between the components;
2) the information about the component of the compound hash table to
which the value belongs is lost, and has to be recalculated if the
value is reinserted.
A more efficient approach is to use internal iteration, that is,
map-like functions, which avoids unnecessary conversions when iterating,
and allows to use an efficient component-wise approach when merging.

Do not use iterator::getValue() in Aggregator.
...
Use separate key and "mapped" value references instead. This is
important for hash tables that do not store the key/"mapped" pair
directly, and cannot provide this interface without some runtime
overhead.
