HAMMER 56C/Many: Performance tuning - MEDIA STRUCTURES CHANGED!

* Implement variable block sizes.  Records at offsets < 1MB use 16K buffers
  while records at offsets >= 1MB use 64K buffers.  This improves performance
  primarily by reducing the number of B-Tree elements we have to stuff.

* Mess around with the deadlock handling code a bit.  It still needs
  a re-think but it works.  Implement low-priority shared locks.
  A low priority shared lock can only be acquired if no other locks are
  held by the thread.

* Implement slow-down code for the record backlog to the flusher and
  reimplement the slow-down code that deals with reclaimed inodes queued
  to the flusher.  This should hopefully fix the kernel memory exhaustion
  issues for M_HAMMER.

* Update layer2->append_off.  It isn't implemented yet but doing this now
  will prevent media incompatibilities later on when it does get implemented.

* Split hammer_blockmap_free() into hammer_blockmap_free() and
  hammer_blockmap_finalize().

* Fix a bug in the delayed-CRC handling related to reblocking.  When
  throwing away a modified buffer, pending CRC requests must also be
  thrown away.

* Fix a bug in the record overlap compare code.  If we cannot return 0
  due to an overlap because the record has been deleted, we must still
  return an appropriate formal code so the scan progresses in the
  correct direction down the red-black tree.

* Make data in the meta-data zone a meta-data buffer structure type so
  it gets synced to disk at the appropriate time.  This may be temporary,
  it's needed to deal with the atime/mtime code but another commit may
  soon make it moot.

* Bump the seqcount so cluster_read() does the right thing when reading
  into a large UIO just after opening a file.

* Do a better job calculating vap->va_bytes.  It's still fake, but its a
  more accurate fake.

* Fix an issue in the BMAP code related to ranges that do not cover the
  requested logical offset.

* Fix a bug in the blockmap code.  If a reservation is released without
  finalizing any allocations within that big-block, another zone can steal
  it out from under the current zone's next_offset, resulting in a zone

  getting returned when B_ERROR is not set.

* Do not B_AGE cluster bufs.

* Pass the block size to both cluster_read() and cluster_write() instead
  of those routines getting the block size from
  vp->v_mount->mnt_stat.f_iosize.  This allows different areas of a file

  This fixes an issue where VFSs were making an extra, unnecessary call
  to BMAP.

* Do not recycle vnodes on the free list until numvnodes has reached
  desiredvnodes.  Vnodes were being recycled when their resident page count
  had dropped to zero, but this is actually too early as the VFS may cache
  important information in the vnode that would otherwise require a number
  of I/O's to re-acquire.  This mainly helps HAMMER (whos inode lookups are
  fairly expensive).

* Do not VAGE vnodes.

* MEDIA CHANGE: The atime has been moved back into the inode data proper.

* PERFORMANCE: The CRC for cached B-Tree nodes was being run on every access
  instead of just the first time.  This was the cause of HAMMER's poor
  directory scanning performance and cpu-intensive write flushes.

  Adjusted to only check the CRC on the initial load into the buffer cache.

* PERFORMANCE: The CRC for modified B-Tree nodes was being regenerated every
  time the node was modified, so a large number of insertions or deletions
  modifying the same B-Tree need needlessly regenerated the CRC each time.

  Adjusted to delay generation of the CRC until just before the buffer is
  flushed to the physical media.

  Just for the record, B-Tree nodes are 4K and it takes ~25uS to run a CRC
  on them.  Needless to say removing the unnecessary calls solved a lot of
  performance issues.

* PERFORMANCE: Removed limitations in the node caching algorithms.  Now more
  then one inode can cache pointers to the same B-Tree node.

* PERFORMANCE: When calculating the parent B-Tree node we have to scan the
  element array to locate the index that points back to the child.  Use a
  power-of-2 algorithm instead of a linear scan.

* PERFORMANCE: Clean up the selection of ip->cache[0] or ip->cache[1] based

  location of the file object's data.
