Added a used #include (don't depend on "vnode_if.h" including ).

Fixed bloatage of `struct inode'. We used 5 "spare" fields for ext2fs,

but when i_effnlink was added to support soft updates, there was only room for 4 spares. The number of spares was not reduced, so the inode size became 260 (on i386's), or 512 after rounding up by malloc(). Use one spare field in `struct dinode' instead of the 5th spare field in the inode and reduced to 4 spares in the inode so that the size is 256 again. Changed the types of the spares in the inode from int to u_int32_t so that the inode size has more chance of being <= 256 under other arches, and downdated ext2fs to match (it was broken to use ints before rev.1.1).

Support compiling with `gcc -ansi'.

keep ahold of buffers, and therefore leave filesystems dirty. I haven't been able to test, but the code compiles. Those who run -current, please test and report back!!! (Sorry :-)). PR: kern/3571 Submitted by: Dirk Keunecke

Removed unused #includes.

Use i386 instead of i386 in ifdefs.

Don't compile unused (debugging?) functions.
