Summary: It's a little surprising to me the clang build passed without these explicit template instantiations!

Per discussion with bolinfest, this brings Eden in line with clang-format.

Summary:
This simplifies the InodePtrImpl class by removing support for pointer-to-const
Inode objects. We don't currently use pointer-to-const Inode objects, and I
don't really anticipate that we will ever need this.
The primary motivating factor behind this diff is a recent change in clang that
breaks the existing code: clang PR31606 prevents children classes from
inheriting template constructor instantiations from their parent which take a
reference to the parent class type as the only argument.
While this could have been fixed by explicitly defining the necessary
constructors in the child class (or simply by overriding newPtrLocked() and
newPtrFromExisting() to return the subclass type), dropping support for
pointer-to-const allows us to simplify the code and resolve this issue.

Summary:
Loading the child inode is necessary to avoid race conditions with other
threads that may be currently trying to load the child inode in question.
This updates the code so that rmdir() and unlink() now share most of their
implementation.

Summary:
Update copyright statements to "2016-present". This makes our updated lint
rules happy and complies with the recommended license header statement.

Summary:
This defines our own custom smart pointer type for Inode objects. This will
provide us with more control over Inode lifetime, allowing us to decide if we
want to unload them immediately when they become unreferenced, or keep them
around for a while.
This will also allow us to fix some memory management issues around EdenMount
destruction. Currently we destroy the EdenMount immediately when it is
unmounted. This can cause issues if other parts of the code are still holding
references to Inode objects from this EdenMount. Our custom InodePtr class
will also allow us to delay destroying the EdenMount until all of its Inodes
have been destroyed.
This diff adds the new pointer types and updates the code to use them, but does
not actually implement destroying unreferenced inodes yet. The logic for that
has proven to be slightly subtle; I will split it out into its own separate
diff.
