Replace multiple nearly-identical copies of code to walk through an FDT
node's interrupts=<...> property creating resource list entries with a
single common implementation.  This change makes ofw_bus_intr_to_rl() the
one true copy of that code and removes the copies of it from other places.

This also adds handling of the interrupts-extended property, which allows
specifying multiple interrupts for a node where each interrupt can have a
separate interrupt-parent.  The bindings for this state that the property
cells contain an xref phandle to the interrupt parent followed by whatever
interrupt info that parent normally expects.  This leads to having a
variable number of icells per interrupt in the property.  For example you
could have <&intc1 1 &intc2 26 9 0 &intc3 9 4>.

Lock ncr(4) and mark it MPSAFE along with various other fixes:
- Use bus_*() instead of bus_space_*().
- Use device_printf().
- Remove unused global variables and the extra warning suppression
  they required.
- Use callout() instead of timeout().

Add strptime(3) support for %U and %W

Add support for the missing POSIX-2001 %U and %W features: the
existing  FreeBSD strptime code recognizes both directives and
validates that the week number lies in the permitted range,
but then simply discards the value.

Initial support for the feature was written by Paul Green with
important fixes by Andrey Chernov. Additional support for
handling tm_wday/tm_yday was written by David Carlier.

In kern_linkat() and kern_renameat(), do not call namei(9) while
holding a write reference on the filesystem.  Try to get write
reference in unblocked way after all vnodes are resolved; if failed,
drop all locks and retry after waiting for suspension end.

The VFS_UNMOUNT() methods for UFS and tmpfs try to establish
suspension on unmount, while covered vnode is locked by VFS, which
prevents namei() from stepping over the mount point.  The thread doing
namei() sleeps on the covered vnode lock, owning the write ref.

Fix fcntl(2) compat32 after r270691.  The copyin and copyout of the
struct flock are done in the sys_fcntl(), which mean that compat32 used
direct access to userland pointers.

Move code from sys_fcntl() to new wrapper, kern_fcntl_freebsd(), which
performs neccessary userland memory accesses, and use it from both
native and compat32 fcntl syscalls.
