Supply default implementation of VOP_RENAME() that does neccessary
unlocks and unreferences for argument vnodes, as expected by
kern_renameat(9), and returns EOPNOTSUPP. This fixes locks and
reference leaks when rename is attempted on fs that does not
implement rename.
Add function vop_rename_fail(9) that performs needed cleanup for locks
and references of the VOP_RENAME(9) arguments. Use vop_rename_fail()
in deadfs_rename().
vm_reserv_alloc_page() should never be called on an OBJT_SG object, just
as it is never called on an OBJT_DEVICE object. (This change should have
been included in r195840.)
Patch the experimental NFS server in a manner analagous to r205661
for the regular NFS server, to ensure that ESTALE is
returned to the client for all errors returned by VFS_FHTOVP().
Patch the regular NFS server so that it returns ESTALE to the client
for all errors returned by VFS_FHTOVP(). This is required to ensure
that EIO doesn't get returned to the client when ZFS is used as the
server file system.
Remove the check for IFF_DRV_OACTIVE right before adding a port into lagg
interface. The check itself seems to be coming from OpenBSD but does not
seem to be useful for our code.

For unhandled actions in xpt_action_default, remember to call
xpt_done for queued requests. This solves the problem of
indefinite hangs for unspecified transports when XPT_SCAN_BUS
is called.
A few minor cosmetics elsewhere.
Move SysV IPC freebsd32 compat shims from freebsd32_misc.c to corresponding
sysv_{msg,sem,shm}.c files.
Mark SysV IPC freebsd32 syscalls as NOSTD and add required
SYSCALL_INIT_HELPER/SYSCALL32_INIT_HELPERs to provide auto
register/unregister on module load.
This makes COMPAT_FREEBSD32 functional with SysV IPC compiled and loaded
as modules.
Introduce SYSCALL_INIT_HELPER and SYSCALL32_INIT_HELPER macros and
neccessary support functions to allow registering dynamically loaded
syscalls from the MOD_LOAD handlers. Helpers handle registration
failures semi-automatically.
For SYSCALL_MODULE_HELPER, use "sys/<syscallname>" module name.
For SYSCALL32_MODULE_HELPER, use "sys32/<syscallname>" module name.
This avoids modules name conflict when compat32 syscall does not
need shims.
Provide groundwork for 32-bit binary compatibility on non-x86 platforms,
for upcoming 64-bit PowerPC and MIPS support. This renames the COMPAT_IA32
option to COMPAT_FREEBSD32, removes some IA32-specific code from MI parts
of the kernel and enhances the freebsd32 compatibility code to support
big-endian platforms.
This MFC is required for MFCs of later changes to the freebsd32
compatibility from HEAD.

For USS820 driver we need to manually reset TX FIFO at each SETUP transaction
because the chip doesn't do this by itself.

It appears that some UVISOR devices do not handle when the clear stall command
is issued at the beginning of the initial IN/OUT data transfers. Reason
unknown, probably firmware fault. Now the stall is only cleared on data
transfer errors.

- make the usb_temp_setup() and usb_temp_unsetup() functions public so that
other modules can generate USB descriptors.
- extend the vendor specific request function by one length pointer argument,
because not all descriptors store the length in the first byte. For example
HID descriptors.
