Ned Bass a3403164d7 zdb: add support for object ranges for zdb -d 
Allow a range of object identifiers to dump with -d. This may
be useful when dumping a large dataset and you want to break
it up into multiple phases, or to resume where a previous scan
left off. Object type selection flags are supported to reduce
the performance overhead of verbosely dumping unwanted objects,
and to reduce the amount of post-processing work needed to
filter out unwanted objects from zdb output.

This change extends existing syntax in a backward-compatible
way. That is, the base case of a range is to specify a single
object identifier to dump. Ranges and object identifiers can
be intermixed as command line parameters.

Usage synopsis:

    Object ranges take the form <start>:<end>[:<flags>]
        start    Starting object number
        end      Ending object number, or -1 for no upper bound
        flags    Optional flags to select object types:
         A    All objects (this is the default)
         d    ZFS directories
         f    ZFS files
         m    SPA space maps
         z    ZAPs
         -    Negate effect of next flag

Examples:

 # Dump all file objects
 zdb -dd tank/fish 0👎f

 # Dump all file and directory objects
 zdb -dd tank/fish 0👎fd

 # Dump all types except file and directory objects
 zdb -dd tank/fish 0👎A-f-d

 # Dump object IDs in a specific range
 zdb -dd tank/fish 1000:2000
