Allow zfs send to exclude datasets

Add support for a -exclude/-X option to `zfs send` to allow dataset 
hierarchies to be excluded.

Snapshots can be excluded using a channel program; however,
this can result in failures with 'zfs send -R'; this option allows 
them to be excluded.  Fortunately, this required a change only to 
cmd/zfs/zfs_main.c, using the already-existing callback argument 
to zfs_send() that is currently unused.
