This initial commit includes both base support for running ZCP scripts, and a small initial library of API calls which support getting properties and listing, destroying, and promoting datasets. Testing: in addition to the included unit tests, channel programs have been in use at Delphix for several months for batch destroying filesystems.

Support for '%f' friends (%f %e %E %g %G) should be removed, since there's no way to supply a floating-point value anyway (all numbers in ZFS LUA are int64_t's).

See README.zfs in that directory for the description of Lua customizations. See zfs-program.8 on how to use the new feature.
