This change is overengineered.
bus_space_{peek,poke}_N does not have to be reentrant nor available for interrupt context.

requested by skrll@

Fix a problem in which a fault occured in an interrupt handler during copyin/copyout was erroneously detected as being occured by copyin.

- keep idepth in faultbuf and compare it to avoid unnecessary fault recovery
- make cpu_set_onfault() nestable to use bus_space_{peek,poke}()
  in hardware interrupt handlers during copyin & copyout.

Add initial support for ARMv8 (AARCH64) (by nisimura@ and ryo@)

- sys/arch/evbarm64 is gone and integrated into sys/arch/evbarm. (by skrll@)
- add support fdt. evbarm/conf/GENERIC64 fdt (bcm2837,sunxi,tegra) based generic 64bit kernel config. (by skrll@, jmcneill@)

Rebase to HEAD as of a few days ago.
