    [2100] (not directly related) cleanup: always destroy old data in setData().
    
    actually the previous implementation seems buggy; it returns the given pionter,
    not the old data.  Worse, this code path isn't tested.  It's a typical example
    of YAGNI; if we don't see the need for it, don't do it; if you cannot regist
    the temptation of making it smarter, at least you should write tests.
    
    At least ZoneTable doesn't need it, so I chose to clean it up.  If and when
    we find it necessary, we should implementation from the scratch, and
    test-driven.

    [2100] use offset pointer for domaintree data.
    
    not absolutely necessary for this branch, but that's the intent anyway.

    [2100] use offset pointer for the underlying tree

    [2100] cleanup: removed removeZone().
    
    right now it doesn't work, and when we need to implement it, the internal
    will need to be substantially updated anyway, so it doesn't make much sense
    to keep the nonworkable version.

    [2100] documentation update

commit 450fef21a63c432b7cd439228ac98a839d335a87
Author: JINMEI Tatuya <jinmei at isc.org>
Date:   Wed Aug 8 17:15:50 2012 -0700

    [2100] updated the return type of findZone().
    
    It now simply returns ZoneData as the data associated with the code;
    the corresponding client implementation will create a zone finder from it.
    also updated some doc.

    [2100] return the created zone data from addZone.

    [2100] improved exception safety.

Author: JINMEI Tatuya <jinmei at isc.org>
Date:   Wed Aug 8 15:36:45 2012 -0700

    [2100] revised addZone() iface: now it only takes name, creates data in it.
    
    also completed the zone table deleter.

    [2100] ensure exception safety in ZoneTable::create using a holder class.
    
    instead of using the ugly try-(catch-all)catch.

commit a98c9ab9a636d075e10f826620fa1aab2ded892c
Author: JINMEI Tatuya <jinmei at isc.org>
Date:   Tue Aug 7 23:59:44 2012 -0700

    [2100] simplify: move definitions to the main class instead of pimpl.
    
    this is mostly private class and is not expected to be referenced outside
    of this psuedo module ("memory"), so it's raltively safer.
    also, the ZoneTable structure will be embedable in a shared memory space,
    so introducing the another pointer indirection will make it unnecessarily
    complicated.
    
    still don't pass tests.

Date:   Tue Aug 7 23:45:21 2012 -0700

    [2100] make the new implementation compile.
    
    added a mostly-empty implementation of ZoneData.
    at this point it's nothing more than "buildable" code.  tests still don't pass.

commit 57de7551b2cc0206f8d1a3ffae9d60b4097ecde1
Author: JINMEI Tatuya <jinmei at isc.org>
Date:   Tue Aug 7 18:06:40 2012 -0700

    [2100] copy the old zone table implementation and tests under "memory" dir.
    
    right now it's a naive copy.  the test wouldn't even compile.
