Add a default value for VM_BCACHE_SIZE_MAX of 400MB. This is copied from
amd64, and is a factor of 3 less than the value previously auto-sized on
a 12GB machine, which would cause an overflow in calculations involving the
maxbcache int, causing bufinit() to loop forever at boot.

When performing a VOP_LOOKUP() as part of UFS1 extended attribute
auto-start, set cnp.cn_lkflags to LK_EXCLUSIVE. This flag must now
be set so that lockmgr knows what kind of lock to acquire, and it
will panic if not specified. This resulted in a panic when using
extended attributes on UFS1 as of locking work present in the 6.x
branch.
This is a RELENG_6_0 merge candidate.

Acquire Giant conditionally in in_addmulti() and in_delmulti() based on
whether the interface being accessed is IFF_NEEDSGIANT or not. This
avoids lock order reversals when calling into the interface ioctl
handler, which could potentially lead to deadlock.
The long term solution is to eliminate non-MPSAFE network drivers.
Discussed with: jhb
Unlock Giant symmetrically with respect to lock acquire order as that's
generally nicer.

| Correct bug that caused the completed "recovery" scb to have its
| timer reset rather than the timer of an SCB still pending on the
| controller after recovery completed. This should correct timeout
| loops seen in the field.

The RIAD5 code is not complete, it does not use nor maintain the parity, so
it does actually only do RAID0. This is not wanted for a production release.

When breaking up a large request into smaller ones for the strategy
routine, create all the child bio objects before starting the
requests, rather than starting them as created. This closes a race
whereby some number of child operations could complete before the
rest were ever created, and prematurely freeing the parent bio.
This fixes the panics installing in VMWare and qemu
