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.

Summary:
InodeError is a subclass of std::system_error that accepts an InodePtr to the
inode that it refers to. This makes it easier to construct error objects that
retain information about the inode they refer to.
InodeError also avoids computing the inode path until the error message is
actually needed. This should make it less expensive in cases where errors are
thrown and handled internally without ever using the human-readable error
message. It is possible that the file may have been renamed or unlinked by the
time the error message is computed. However, this race condition might still
exist even if we computed the path at the time when the error is constructed.
getLogPath() will construct a usable human-readable string even if the file has
been unlinked.
