When you create a pool, zfs writes vd->vdev_enc_sysfs_path with the
enclosure sysfs path to the fault LEDs, like:
vdev_enc_sysfs_path = /sys/class/enclosure/0:0:1:0/SLOT8
However, this enclosure path doesn't get updated on successive imports
even if enclosure path to the disk changes. This patch fixes the issue.

FreeBSD's pidfile_open() says nothing about the flags of the files it
opens, but we can't do anything about it anyway; the implementation does
open all files with O_CLOEXEC

This change updates the documentation to refer to the project
as OpenZFS instead ZFS on Linux. Web links have been updated
to refer to https://github.com/openzfs/zfs. The extraneous
zfsonlinux.org web links in the ZED and SPL sources have been
dropped.

Since 0.7.0, zpool import would unconditionally block on udev for 30
seconds. This introduced a regression in initramfs environments that
lack udev (particularly mdev based environments), yet use a zfs userland
tools intended for the system that had been built against udev. Gentoo's
genkernel is the main example, although custom user initramfs
environments would be similarly impacted unless special builds of the
ZFS userland utilities were done for them. Such environments already
have their own mechanisms for blocking until device nodes are ready
(such as genkernel's scandelay parameter), so it is unnecessary for
zpool import to block on a non-existent udev until a timeout is reached
inside of them.
Rather than trying to intelligently determine whether udev is available
on the system to avoid unnecessarily blocking in such environments, it
seems best to just allow the environment to override the timeout. I
propose that we add an environment variable called
ZPOOL_IMPORT_UDEV_TIMEOUT_MS. Setting it to 0 would restore the 0.6.x
behavior that was more desirable in mdev based initramfs environments.
This allows the system user land utilities to be reused when building
mdev-based initramfs archives.
