zpool and zed place scripts in subdirectories of libexecdir. Some
distributions locate architecture independent scripts in other locations
(e.g. Debian). To avoid these paths getting out of sync, centralize the
definitions.
Build zfs-test's default.cfg by Makefile. Use the new directory
logic building tests/zfs-tests/include/default.cfg.in.

* Add a zed script to kick off a scrub after a resilver. The script is
disabled by default.
* Add a optional $PATH (-P) option to zed to allow it to use a custom
$PATH for its zedlets. This is needed when you're running zed under
the ZTS in a local workspace.
* Update test scripts to not copy in all-debug.sh and all-syslog.sh by
default. They can be optionally copied in as part of zed_setup().
These scripts slow down zed considerably under heavy events loads and
can cause events to be dropped or their delivery delayed. This was
causing some sporadic failures in the 'fault' tests.

This commit updates the copyright boilerplate within the ZED subtree.
The instructions for appending a contributor copyright line have
been removed. Manually maintaining copyright notices in this
manner is error-prone, imprecise at a file-scope granularity, and
oftentimes inaccurate. These lines can become a pernicious source of
merge conflicts. A commit log is better suited to maintaining this
information. Consequently, a line has been added to the boilerplate
to refer to the git commit log for authoritative copyright attribution.
To account for the scenario where a file may become separated from
the codebase and commit history (i.e., it is copied somewhere else),
a line has been added to identify the file's origin.

The executables invoked by the ZED in response to a given zevent
have been generically referred to as "scripts". By convention,
these scripts have aimed to be /bin/sh compatible for reasons of
portability and comprehensibility. However, the ZED only requires
they be executable and (ideally) capable of reading environment
variables. As such, these scripts are now referred to as ZEDLETs
(ZFS Event Daemon Linkage for Executable Tasks).

zed monitors ZFS events. When a zevent is posted, zed will run any
scripts that have been enabled for the corresponding zevent class.
Multiple scripts may be invoked for a given zevent. The zevent
nvpairs are passed to the scripts as environment variables.
Events are processed synchronously by the single thread, and there is
no maximum timeout for script execution. Consequently, a misbehaving
script can delay (or forever block) the processing of subsequent
zevents. Plans are to address this in future commits.
Initial scripts have been developed to log events to syslog
and send email in response to checksum/data/io errors and
resilver.finish/scrub.finish events. By default, email will only
be sent if the ZED_EMAIL variable is configured in zed.rc (which is
serving as a config file of sorts until a proper configuration file
is implemented).
