Add simple helpers to convert a vnode->v_type to a inode->i_mode. These should be used sparingly but they are handy to have.
Updated AUTHORS, COPYING, DISCLAIMER, and INSTALL files. Added standardized headers to all source file to clearly indicate the copyright, license, and to give credit where credit is due.
Rework vnodes to be based on the slab cache, just like on Solaris. git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@45 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c
