Property to allow sets of features to be specified; for compatibility with specific versions / releases / external systems. Influences the behavior of 'zpool upgrade' and 'zpool create'. Initial man page changes and test cases included. Brief synopsis: zpool create -o compatibility=off|legacy|file[,file...] pool vdev... compatibility = off : disable compatibility mode (enable all features) compatibility = legacy : request that no features be enabled compatibility = file[,file...] : read features from specified files. Only features present in *all* files will be enabled on the resulting pool. Filenames may be absolute, or relative to /etc/zfs/compatibility.d or /usr/share/zfs/compatibility.d (/etc checked first). Only affects zpool create, zpool upgrade and zpool status. ABI changes in libzfs: * New function "zpool_load_compat" to load and parse compat sets. * Add "zpool_compat_status_t" typedef for compatibility parse status. * Add ZPOOL_PROP_COMPATIBILITY to the pool properties enum * Add ZPOOL_STATUS_COMPATIBILITY_ERR to the pool status enum An initial set of base compatibility sets are included in cmd/zpool/compatibility.d, and the Makefile for cmd/zpool is modified to install these in $pkgdatadir/compatibility.d and to create symbolic links to a reasonable set of aliases.
