Ajay Kaher c1504e5102 eventfs: Implement eventfs dir creation functions
Add eventfs_file structure which will hold the properties of the eventfs
files and directories.

Add following functions to create the directories in eventfs:

eventfs_create_events_dir() will create the top level "events" directory
within the tracefs file system.

eventfs_add_subsystem_dir() creates an eventfs_file descriptor with the
given name of the subsystem.

eventfs_add_dir() creates an eventfs_file descriptor with the given name of
the directory and attached to a eventfs_file of a subsystem.

Add tracefs_inode structure to hold the inodes, flags and pointers to
private data used by eventfs.
