  Log:
  HAMMER 33/many: Expand transaction processing, fix bug in B-Tree
  
  * Expand transaction processing to cover more of the code space for
    upcoming undo code.
  
  * Fix a bug in the btree_split_leaf(), the separator would sometimes not
    properly be to the left of the split point, resulting in a panic.
    Temporarily add many more assertions to btree_split_leaf().
  
  * Improve the critical path for blockmap lookups, the (newly) passed trans
    already contains a referenced root volume so the blockmap code does not
    have to acquire one.
