Module Name:    src
Committed By:   reinoud

Modified Files:
        src/sys/conf: files
        src/sys/kern: vfs_init.c
Added Files:
        src/sys/kern: vfs_dirhash.c
        src/sys/sys: dirhash.h

Log Message:
Add generic FS agnostic directory hashing support. Currently only in use by
UDF. Future users could be msdosfs, ufs, nilfs2 (when ready), cd9660 etc.

Note that its not the same as UFS's DIRHASH support; UFS would need a good
cleanup/splitout of directory operations to adopt to this new directory
hashing support since most directory operations are interweaved with the
vnops itself. This is a TODO.
