HAMMER VFS - Use full-block undos for B-Tree nodes

* Use a full-block undos instead of small byte-range undos for
  B-Tree nodes.

  There is no bug here per-say, but we are trying to improve
  HAMMER's ability to recover after a power failure where a disk
  drive is writing to the platter at the time of the failure.
  While we have no control over any unrelated sectors that might
  get smashed by such an event, the concern is that sectors being
  specifically written might get corrupted beyond the ability for
  the byte-range undo to fix.

  The reason is that if, say, only 50 bytes in a B-Tree node need
  updating, HAMMER must still do a 16K physical write to disk, so
  really any portion of that 16K can wind up corrupt on a power
  failure, not just the 50 bytes being changed.

  So instead of writing a byte-ranged 50-byte UNDO we now write
  a 16K undo for B-Tree elements.

* The hope is that this will improve cases where HAMMER has become
  unmountable due to CRC errors in the B-Tree closer to the root of
  the B-Tree (which are usually updated to update only the mirror_tid)

Use GCC's builtin offset_of as the first option

Other than C++ code, the GCC offsetof builtin was never getting used.
The version that did get expanded could not be used for array
declarations on GCC 4.5 and later because it wasn't considered a
constant expression by those later GCC compilers.

The first symptom was seen when building world with GCC 4.6, but the
the offsetof expansion was finally identified as the cause of the
problem while discussion PostgreSQL 9.1 build failures on DragonFly.
Since DragonFly was the only platform exibiting the behavior, the
problem was narrowed down to the offsetof macro or the compiler itself.
Fixing the macro allowed the unpatched pgsql to compile.
