rev2 of hfs dentry code

i went through and rewrote the catalogue caching to be almost
identical to what the 2.1.x inode.c does. i'm still not sure if i have
everything correct, so i would like people to test the code. there's
probably areas of redundancy as well. here's a synopsis of what the
code does (read the ChangeLog for more info):
1) hopefully a better cache pruning scheme.
2) hashes everything to lowercase.
3) the catalogue cache should now be SMP safe due to the
re-write.
4) moved the inline dentry functions to hfs.h.
5) fixed notify_change.
6) made df -i report allocation blocks available/free as i
thought that would be a useful thing to know and it seemed
semantically similar enough to inodes to warrant.
6) changed version to 0.95+asun2
i've tested it with netatalk and haven't noticed any problems there.
current issues:
1) it really needs people to bang on it. if you want to test
the catalogue caching code, i suggest editing catalog.c and
reducing CCACHE_MAX to something small like 32. that's how
i tested it.
2) the current locations of various bits may not be the best.
things will definitely have to be separated better if the
code gets ported to *BSD or something like that.
what the files mean:
1) 0.95-dentry2.diff.gz is the diff against 0.95
2) dentry-dentry2.diff.gz is the diff against the first
version.
3) hfs_fs-dentry2.tar.gz is the complete tarball.
you can get it at <ftp://ftp.u.washington.edu:/public/asun>.
have fun,
