    hammer2 - freemap part 2 - cleanup & performance pass
    
    * Increase minimum I/O from 1K to 16K (HAMMER2_LBUFSIZE).
    
    * Adjust some use cases, increasing the smallest indirect block to the
      minimum IO size 4K->16K.
    
    * The BREF_TYPE_FREEMAP_LEAF bitmap is now embedded in the chain, allowing
      us to use the 256 byte bitmaps more safely.  As with inodes, a read-in
      involves using a larger buffer-cache buffer and then copying the data
      into the chain.
    
    * Avoid unnecessary reads from disk when allocating blocks that are less
      than the minimum IO size.  If it is determined that the bitmap bits
      covering the minimum IO size are 0 (unallocated), we pre-validate the
      larger buffer cache buffer so the later bread() does not have to issue
      any actual reads.
    
      Pre-validation for allocations larger than or equal to the minimum IO
      size is already handled in the chain locking code.
    
      With this change, a cpdup into H2 will issue mostly writes and is able
      to avoid nearly all reads.
    
    * Make some progress formalizing chain-embedded data.

    lvm: Fix two wrong array indexes.

    hammer2 - freemap part 1 - initial block allocator and media support
    
    * Freemap document (FREEMAP in this directory)
    
    * temporarily turn off clustering until the freemap gets that capability
      (mixed buffer sizes can be adjacent atm).
    
    * Remove the freemap_blockref[1] from the volume header and replace it
      with a blockset array (8 blockrefs).
    
    * Implement dynamic creation of freemap nodes and leafs on an as-needed
      basis using the normal indirect block creation code.  Most of the standard
      file handling code is reused for the freemap support.
    
    * Major cleanup of hammer2_chain.c, the duplication code, the indirect
      block creation and handling, and the chain->flag handling.

    hammer2 - flush sequencing part 8 - stabilization pass
    
    * On this commit it appears that the cpdup / test is fully validating
      on remount and chain memory leaks are gone.
    
    * Remove a hack when creating a hardlink.  The original directory entry
      is duplicated to create the invisible hardlink target in the common
      parent directory, but the original directory entry is then not deleted.
      Instead I was modifying it (which generally did not cause a delete/duplicate
      sequence) and then changing the inode type to HARDLINK and setting
      the OPFLAG_DIRECTDATA flag.
    
      The problem with this is that the inode's core RBTREE was left intact,
      but as a DIRECTDATA inode the flusher ignores it.  This prevented the
      flusher from clearing the MOVED but on the children and resulted in the
      memory leak.
    
      What I do now is delete/duplicate the original inode, give the duplicate
      a fresh core, and then modify the duplicate instead of the original to be
      the special HARDLINK type w/OPFLAG_DIRECTDATA.  This removes the special
      case.

    hammer2 - Add 'hash' directive
    
    * Add hammer2 hash <filename>* which calculates and prints out the
      64-bit directory hash code for a filename, for debugging purposes.

    hammer2 - flush sequencing part 7 - stabilization pass
    
    * Simplify the next_parent / IPACTIVE handling.  Just ref next_parent
      unconditionally, it's the easiest solution.
    
    * More work on CHAIN_SUBMODIFIED flag handling during the flush.  The
      flush seems to catch all the edge cases now (cross fingers).
    
    * Do a better job cleaning up unreferenced chains.

            contrib/libedit/src/readline.c

    libedit: Update to version 2012-12-13
    
    There have been three releases since libedit was imported as a vendor
    branch, but the changelog is simply "sync with NetBSD" for each one.
    
    The main item of interest is that widechar support has been added
    for real this time.  Previously all the man pages were in place but
    the library didn't actually have the support.
    
    A minor item of note is that NetBSD finally implemented the
    rl_completion_word_break_hook which reduces the number of files
    with local modifications.

    Merge branch 'vendor/TCSH'
    
    Conflicts:
            contrib/tcsh-6/sh.decls.h

    tcsh: Add more local modifications
    
    - Remove whitespace from existing local modifications of tcsh.
    - Remove two unused variables which break the build with -Werror.
    - Disable format warning completely because every xprintf with %S
      parameter breaks the build (it wants the argument to be cast to
      wchar_t* rather than the provided Char*).

    tcsh: Update from version 6.17.00 to 6.18.01
    
    There were 8 releases since the last tcsh update.
    The changes of each are listed below.
    
    When the output of "csh --version" is compared to the previous version,
    two differences are noticed.  The first is dpsm is not showing.  This is
    correct because it cannot be set simultaneously with widestar as it was.
    The second difference is the system malloc is no longer used.  The
    sources inside say system malloc can be significantly slower and that
    memory statistics will not be available if used.  It also went to pains
    to remove the option even if hard-coded in config_p.h.
    
    The identifier for --version was fixed for x86_64 platform by
    updating host.defs file.
    
    V6.18.01 - 20120214
      5. fix interruptible wait again
      4. ignore bogus compiler overflow message
      3. cleanup ifdefs in utmp code, and provide default array entries
      2. Ignore #machine entries in host.defs
      1. Detect missing ) in gethost.c (Corinna Vinschen)
    
    V6.18.00 - 20120114

    hammer2 - flush sequencing part 6 - stabilization pass
    
    * Fix bug when chains are e.g. delete/duplicated where a flush can occur
      out of order and retire more recent chain structures leaving older
      CHAIN_DELETED structures behind.  This caused the merged chain_find
      and lookup/iteration code to improperly believe a slot was empty when
      in fact the parent's bref array had a valid blockref.
    
      Fixed by flagging the discrete chain->next_parent linkages with
      CHAIN_IPACTIVE and adding a ref to the chain, which prevents them
      from being retired out of order.  This is currently being done
      unconditionally (and probably has to be done unconditionally).
    
    * Fix bug related to the clearing of SUBMODIFIED during a flush.  Generally
      speaking a flush pass clears SUBMODIFIED if no children were deferred.
    
      The bug is that higher-level indirect-block chains closer to the root
      are typically only modified during the flush as the deeper chains are
      flushed recursively and rolled up into the parents on the way back up.
      Because of this, these higher-level chains could represent more than one
      flush synchronization point.  When this situation is detected we now
      set SUBMODIFIED here too.
    
    * Consolidate ip->chain adjustments into the hammer2_inode_repoint()
      procedure.  Remove hammer2_inode_put().

    bnx: Use different RX coalesce BDs for polling and interrupt mode
    
    The value set by this commit for polling mode improves tiny packets
    forwarding performance by +250Kpps in normal mode and +120Kpps in
    fast mode.

    hammer2 - flush sequencing part 5 - more flush synchronization work
    
    * Get rid of chain->parent, replacing it with chain->above which is a
      pointer to the core common to the possibly multiple parents.  Due
      to the multi-parenting, chain->parent was rather ad-hoc so getting
      rid of makes the code more clear.
    
    * Adjust several APIs which used to take a locked parent of chain to
      instead take the core common to multiple parents of chain.
    
    * Rework how CHAIN_MOVED is cleared.  The code works better but still
      has bugs which can leave chains hanging and unflushed on umount.
    
    * Rework the lastdrop function significantly.
    
    * Continue working on automatic delete/duplicate operation when a
      modification crosses a synchronization boundary.  This code is now
      mostly implemented.
    
    * Continue working on the flush filter which is responsible for
      differentiating modifications made before and after the synchronization
      point.  The filter is now mostly implemented.
    
    * Use spinlock protection on the rbtree, allowing manipulation of children
      without having to lock a specific parent chain (which wouldn't help much

    bnx: In polling mode, force chip update status block for status changes
    
    If the status block updating is not forced, we will always see staled
    status changes in polling mode, which causes bunch of unnecessary register
    reading.
    
    For status changes sharing status block with transmission, staled status
    changes probably won't linger for too much time, since any data transmit
    completion will cause status block to be updated.  However, for status
    changes using its own status block, staled status changes will be there
    until the chips are stopped.

    hammer2 - flush sequencing part 4 - stabilization and cleanup, flush sep
    
    * Fix bugs in the handling of DIRECTDATA.  The data for small
      files <= 512 bytes is stored in the inode itself using the
      area that would otherwise contain the indirect block table.
    
      Cleanup the flag handling for this data, ensure synchronous bwrite()s
      for this data area (the strategy code for direct-data reads and writes
      doesn't actually do any I/O), and ensure proper read-before-write
      operation.
    
    * Adjust hammer2_inode_create() and hammer2_chain_modify_ip() to take/return
      (*chainp).
    
    * Change the inode locking APIs to return the locked chain (unlocking APIs
      take the locked chain as an argument).  This allows the chain to be
      manipulated by the code inbetween, including replacing it with other
      chains, instead of the mess we had before where ip->chain had an implied
      lock associated with it.
    
      With this change, replacing ip->chain is just a matter of adjusting
      ref counts and not also having to worry about locks.
    
    * Modify the inode chain proactively instead of indirectly.
