f3bde19b74 Do not use iterators in find() and emplace() methods of hash tables. 
Instead, these methods return a pointer to the required data as they are
stored inside the hash table. The caller uses overloaded functions to
get the key and "mapped" values from this pointer. Such an interface
avoids the need for constructing iterator-like wrapper objects, which is
especially important for compound hash tables such as the future
StringHashMap.

Add new dictionary layout (sparse_hashed) that is more memory efficient 
With this new layout, sparsehash will be used over default HashMap,
sparsehash is more memory efficient but it is also slower.

So in a nutshell:
- HashMap uses ~2x more memory then sparse_hash_map
- HashMap ~2-2.5x faster then sparse_hash_map
(tested on lots of input, and the most close to production was
dictionary with 600KK hashes and UInt16 as value)

TODO:
- fix allocated memory calculation
- getBufferSizeInBytes/getBufferSizeInCells interface
- benchmarks

v0: replace HashMap with google::sparse_hash_map
v2: use google::sparse_hash_map only when <sparse> isset to true
v3: replace attributes with different layout
v4: use ch hash over std::hash

da8f67123f Improve error handling in cache dictionaries: 
allow using expired values while the source of a cache dictionary doesn't respond;
clone the source after an error to reset connections;
don't ask the source for a little time after error;
show the last exception in system.dictionaries for a cache dictionary too.

b4384ce2a9 Dictionaries can be loaded in parallel. 
A bad dictionary cannot block all the loading anymore.
Implemented really lazy loading of external dictionaries.
Provided more detailed information about the loading of each dictionary
to make diagnostics easier.
