This is the kernel Lite/2 commit. There are some requisite userland changes, so don't expect to be able to run the kernel as-is (very well) without the appropriate Lite/2 userland changes. The system boots and can mount UFS filesystems. Untested: ext2fs, msdosfs, NFS Known problems: Incorrect Berkeley ID strings in some files. Mount_std mounts will not work until the getfsent library routine is changed. Reviewed by: various people Submitted by: Jeffery Hsu <hsu@freebsd.org>

Add type arg to ffs_mountfs and avoid examining v_tag to find out if MFS is getting a free ride. Use generic ufs_reclaim().

Clustered read and write are switched at mount-option level. 1. Clustered I/O is switched by the MNT_NOCLUSTERR and MNT_NOCLUSTERW bits of the mnt_flag. The sysctl variables, vfs.foo.doclusterread and vfs.foo.doclusterwrite are deleted. Only mount option can control clustered I/O from userland. 2. When foofs_mount mounts block device, foofs_mount checks D_CLUSTERR and D_CLUSTERW bits of the d_flags member in the block device switch table. If D_NOCLUSTERR / D_NOCLUSTERW are set, MNT_NOCLUSTERR / MNT_NOCLUSTERW bits will be set. In this case, MNT_NOCLUSTERR and MNT_NOCLUSTERW cannot be cleared from userland. 3. Vnode driver disables both clustered read and write. 4. Union filesystem disables clutered write. Reviewed by: bde

Fix all areas of the system (or at least all those in LINT) to avoid storing socket addresses in mbufs. (Socket buffers are the one exception.) A number of kernel APIs needed to get fixed in order to make this happen. Also, fix three protocol families which kept PCBs in mbufs to not malloc them instead. Delete some old compatibility cruft while we're at it, and add some new routines in the in_cksum family.

Introduced a type `vop_t' for vnode operation functions and used it 1138 times (:-() in casts and a few more times in declarations. This change is null for the i386. The type has to be `typedef int vop_t(void *)' and not `typedef int vop_t()' because `gcc -Wstrict-prototypes' warns about the latter. Since vnode op functions are called with args of different (struct pointer) types, neither of these function types is any use for type checking of the arg, so it would be preferable not to use the complete function type, especially since using the complete type requires adding 1138 casts to avoid compiler warnings and another 40+ casts to reverse the function pointer conversions before calling the functions.
