d1807f168e nvpair: Constify string functions
After addressing coverity complaints involving `nvpair_name()`, the
compiler started complaining about dropping const. This lead to a rabbit
hole where not only `nvpair_name()` needed to be constified, but also
`nvpair_value_string()`, `fnvpair_value_string()` and a few other static
functions, plus variable pointers throughout the code. The result became
a fairly big change, so it has been split out into its own patch.

ZED: Fix uninitialized value reads
Coverity complained about a couple of uninitialized value reads in ZED.

 * zfs_deliver_dle() can pass an uninitialized string to zed_log_msg()
 * An uninitialized sev.sigev_signo is passed to timer_create()

The former would log garbage while the latter is not a real issue, but
we might as well suppress it by initializing the field to 0 for
consistency's sake.

Fix usage of zed_log_msg() and zfs_panic_recover()
Coverity complained about the format specifiers not matching variables.
In one case, the variable is a constant, so we fix it. In another, we
were missing an argument (about which coverity also complained).

861166b027 Remove bcopy(), bzero(), bcmp()
bcopy() has a confusing argument order and is actually a move, not a
copy; they're all deprecated since POSIX.1-2001 and removed in -2008,
and we shim them out to mem*() on Linux anyway

976246fadd Add illumos FMD ZFS logic to ZED -- phase 2
The phase 2 work primarily entails the Diagnosis Engine and
the Retire Agent modules. It also includes infrastructure
to support a crude FMD environment to host these modules.

The Diagnosis Engine consumes I/O and checksum ereports and
feeds them into a SERD engine which will generate a corres-
ponding fault diagnosis when the SERD engine fires. All the
diagnosis state data is collected into cases, one case per
vdev being tracked.

The Retire Agent responds to diagnosed faults by isolating
the faulty VDEV. It will notify the ZFS kernel module of
the new VDEV state (degraded or faulted). This agent is
also responsible for managing hot spares across pools.
When it encounters a device fault or a device removal it
replaces the device with an appropriate spare if available.
