Rather that previous attempts to add tftpfs support at the same time as NFS
support. This time decide on a proper URI parser rather than hacks.
root-path can now be define the following way:
For tftpfs:
tftp://ip/path
tftp:/path (this one will consider the tftp server is the same as the one where
the pxeboot file was fetched from)
For nfs:
nfs:/path
nfs://ip/path
The historical
ip:/path
/path
are kept on NFS

The adapter firmware in general does not accept PDUs larger than 64k - 1
bytes in size. Sending crypto requests larger than this size result in
hangs or incorrect output, so reject them with EFBIG. For requests
chaining an AES cipher with an HMAC, the firmware appears to require
slightly smaller requests (around 512 bytes).

The motivation for this is two-fold.
1. Some old WD SATA disks may appear as if they need to be spun up
when they are already spinning. Those disks would respond with
an error to the spin-up request.
2. Even if we really fail to spin up the disk, we still can try to
proceed to the subsequent phases. If we fail later on, then no
difference. Otherwise we get a chance to communicate with the
disk which is better than completely ignoring it, because a user
can try to recover the disk.

This modification adds the capability to newsyslog to write the
rotation message in a format that is compliant with RFC5424. This
capability is enabled on a per-log file basis through a new value
("T") in the flags field in newsyslog.conf. This is useful on systems
that use the RFC5424 format for log files so that the rotation message
format matches that of the other log messages. There has been recent
mention of adding an RFC5424 compliant mode to syslogd and at least
one alternative system log daemon (rsyslogd) that already has the
capability to use that format.

Check for the existence of ptrace.[sS] in the .depend file to determine

If we do a scrub while a leaf device is offline (via "zpool offline"),
we will inadvertently clear the DTL (dirty time log) of the offline
device, even though it is still damaged. When the device comes back
online, we will incompletely resilver it, thinking that the scrub
repaired blocks written before the scrub was started. The incomplete
resilver can lead to data loss if there is a subsequent failure of a
different leaf device.
The fix is to never clear the DTL of offline devices. Note that if a
device is onlined while a scrub is in progress, the scrub will be
restarted.
The problem can be worked around by running "zpool scrub" after
"zpool online".

Since we support whole-disk configuration for boot pool, we also will need
whole disk support with UEFI boot and for this, zpool create should create efi-
system partition.
I have borrowed the idea from oracle solaris, and introducing zpool create -
B switch to provide an way to specify that boot partition should be created.
However, there is still an question, how big should the system partition be.
For time being, I have set default size 256MB (thats minimum size for FAT32
with 4k blocks). To support custom size, the set on creation "bootsize"
property is created and so the custom size can be set as: zpool create B -
o bootsize=34MB rpool c0t0d0
After pool is created, the "bootsize" property is read only. When -B switch is
not used, the bootsize defaults to 0 and is shown in zpool get output with
value ''. Older zfs/zpool implementations are ignoring this property.

It's currently nearly impossible to trace what process places a hold on
a vnode, as the only ways holds are place is via the `VN_HOLD()` and
`VN_HOLD_CALLER()` macros, which inline the bumping of `v_count`. Adding
static DTrace probes to these macros would enable tracing of where
specific vnode references come from.
For completeness and symmetry, a similar static probe should be added to
`vn_rele()` and `vn_rele_dnlc()`.

- insert disk into slot B
- check that hotspare moved back to "avail" state (if spare was used)

It's possible, although extremely rare, that the zfs_get_done() callback is
executed before dmu_sync() returns.
In that case the znode's range lock is dropped and the znode is unreferenced.
Thus, the assertion can access some invalid or wrong data via the zp pointer.
