https://gerrit.named-data.net/2980 corrects code style in NameTree and name tree entry.
I intentionally keep "refactoring" minimal, and avoid moving code up and down.

https://gerrit.named-data.net/3015 refactors NameTree iterator in preparation for shared_ptr changes.
All existing test cases are passing.

https://gerrit.named-data.net/3017 refactors NameTree hashtable to make it a separate component.
patchset1 has the API only. I will wait for reviews on the API before proceeding further.

https://gerrit.named-data.net/3017 patchset2 has partial implementation of NameTree hashtable.
I haven't converted iterator part; to avoid conflicts, I won't do that until https://gerrit.named-data.net/3015 is approved.

https://gerrit.named-data.net/3049 patchset2 deletes functions deprecated in previous two commits, and improves Doxygen.
https://gerrit.named-data.net/3050 patchset3 changes return type of findExactMatch and findLongestPrefixMatch to Entry*.

https://gerrit.named-data.net/3058 ensures NameTree::lookup(tableEntry) to have "find or insert" semantics equivalent to Name::lookup(Name).
It handles special cases such as Fib::s_emptyEntry and PIT entry ending with digest attached on one-shorter-prefix.
Prior usages of NameTree::lookup(tableEntry) have been replaced with NameTree::getEntry if insertion is undesired.
https://gerrit.named-data.net/3059 changes the return type of NameTree::lookup from shared_ptr<Entry> to Entry&.

https://gerrit.named-data.net/3064 simplifies Fib::findLongestPrefixMatch and StrategyChoice::findEffectiveStrategy.
https://gerrit.named-data.net/3065 deletes unnecessary name_tree::Iterator destructor.
It was introduced when I initially designed the iterator to be a base class, and full/partial/all-match have iterator subclasses; that idea didn't work, but I forgot to delete the destructor.

https://gerrit.named-data.net/3068 changes cleanupOnFaceRemoval procedure so it doesn't rely on weak_ptr<name_tree::Entry>.
https://gerrit.named-data.net/3069 makes Node the sole owner of Entry. It allocates and deallocates Entry through new and delete.
No shared_ptr<name_tree::Entry> exist after this change.

https://gerrit.named-data.net/3069 patchset6 makes Entry a member field of Node to avoid separate memory allocations for Node and Entry.
