  When buffering an insert to a prefix index of a variable-length column,
  do not incorrectly mark the column as fixed-length.  (Bug #28138)
  
  ibuf_entry_build(): Instead of prefix_len, pass fixed_len to
  dtype_new_store_for_order_and_null_size().  Add debug assertions.

  Potential fix for Bug#25645:
  
  "Move innobase_release_stat_resources(trx) outside the 'if' in
  ha_innobase::external_lock(). That would add more safety that whatever
  MySQL does at a query end, there would be no risk of a hang on the btr
  search latch."
  
  Also call innobase_release_temporary_latches() in the beginning of
  ha_innobase::close().

  Revision r1454:
  branches/5.0: merge r1453 from trunk:
  
  Bugfix: only call innobase_release_temporary_latches() in case of current_thd

  Do not return error in ha_innobase::info if srv_force_recovery >= 4. This is to allow for
  normal processing of the query by MySQL instead of generating an error.
