a disk image open fails.

Fix the led 'gpios' definition to match the description on
sys/boot/fdt/dts/bindings-gpio.txt.  Make the led pin an output, add the
missing flag field.  No functional change (gpioled(4) isn’t supported on
FDT systems yet).

Fix fdisk(8) to create 2TB partitions on disks larger than 2TB, rather than
only being able to create 1TB partitions:
o) Use an unsigned 32-bit quantity to store the number of disk sectors.
o) Detect overflow of said 32-bit quantity and clamp to 2^32.
o) Rather than returning the disk sector count from get_params, return 0 on
   success, since its return value is only ever compared to -1 to detect
   failure.  This would cause returning 2^32 sectors to be interpreted as an
   error.

Revert r258672. We clearly don't compile libraries enough times.
Disable an assertion that relies on some code[1] that isn't in HEAD yet.

Fix bug introduced at r252226, when udata argument passed to bucket_alloc()
was used without making sure first that it was really passed for us.

On some of my systems this bug made user argument passed by ZFS code to
uma_zalloc_arg() unexpectedly block UMA per-CPU caches for those zones.
Don't count bucket allocation failures for UMA zones as their own failures.
There are good reasons for this to happen, such as recursion prevention, etc.
and they are not fatal since buckets are just an optimization mechanism.
Real bucket allocation failures are any way counted by the bucket zones
themselves, and we don't need double accounting there.
Add constants for use in interrogating various fiber and copper connectors
most often used with network interfaces.

The SFF-8472 standard defines the information that can be retrieved
from an optic or a copper cable plugged into a NIC, most often
referred to as SFP+.  Examples of values that can be read
include the cable vendor's name, part number, date of manufacture
as well as running data such as temperature, voltage and tx
and rx power.

Copious comments on how to use these values with an I2C interface
are given in the header file itself.

Make UMA to not blindly force offpage slab header allocation for large
(> PAGE_SIZE) zones.  If zone is not multiple to PAGE_SIZE, there may
be enough space for the header at the last page, so we may avoid extra
header memory allocation and hash table update/lookup.

ZFS creates bunch of odd-sized UMA zones (5120, 6144, 7168, 10240, 14336).
This change gives good use to at least some of otherwise lost memory there.
