Summary:
Define InodePtr, TreeInodePtr, and FileInodePtr as aliases for std::shared_ptr
of the underlying inode type. This also updates all of the code to use these
new type names.
This will make it easier swap out std::shared_ptr with a custom pointer type in
the future. (I believe we will need a custom type in the future so that we
can have more precise control of the reference counting so we can load and
unload Inode objects on demand. std::shared_ptr::unique() doesn't quite
provide the flexibility we need, and is also being deprecated in C++17.)

Summary:
This updates the InodeBase code to track its location in the filesystem.
Since we do not support hard links, each inode has a single path where it
exists.
Tracking this data allows us to implement getPath() as a method of InodeBase.
This code is not really complete yet, but it seems worth getting the current
code in as-is. The location data is not updated properly on unlinks or
renames, but it looks like the existing InodeNameManager code does not get
updated either. I am working on some additional refactoring of inode object
management, and it will be easier to come back and fix the unlink and rename
handling after this refactoring is further along.

Summary:
Move the InodeBase class from the lower-level fusell code up to the
eden/fs/inodes layer, now that everything else that uses it is in
eden/fs/inodes.
I plan to start changing the ownership model of inode objects a bit, and this
will allow the InodeBase class to interact with EdenDispatcher and other
classes in eden/fs/inodes.
