Make 'unmount -a[f]' calls less evil by introducing __ZFS_POOL_EXCLUDE environment variable (in addition to __ZFS_POOL_RESTRICT one) which tells zpool_iter() and zfs_iter_root() to skip listed pools. The function was renamed to zpool_skip_pool() and made global. Modified check is also used in unshare_unmount() in zfs_main.c.
zfstest.ksh modified to set __ZFS_POOL_EXCLUDE to KEEP contents (or just root pool if KEEP isn't set). Fix the KEEP->regex conversion while here. This was already reviewed and submitted for RTI, but as it has stalled, let's try (and test) this here.
