  branches/zip: Skip the undo log size check on REDUNDANT and COMPACT tables.

  In ROW_FORMAT=DYNAMIC and ROW_FORMAT=COMPRESSED, column prefix indexes
  require that prefixes of externally stored columns be written to the
  undo log. This may make the undo log record bigger than the record on
  the B-tree page.  The maximum size of an undo log record is the page
  size.  That must be checked for, in dict_index_add_to_cache().

  dict_index_add_to_cache(): Skip the undo log size check for REDUNDANT
  and COMPACT tables. These tables store prefixes of externally stored
  columns locally within the clustered index record.  There are no special
  considerations for the undo log record size.

  innodb-index.test: Ensure that the check exists for ROW_FORMAT=DYNAMIC,
  but not for ROW_FORMAT=COMPACT.

  This fixes issue #99.  rb://28 approved by Sunny.

  Fix Mantis issue#61:

  In row_undo_ins_parse_undo_rec(): if we find that a table has no indexes
  (dict_table_get_first_index() returns NULL) do not try to call
  trx_undo_rec_get_row_ref() with a NULL pointer because that would lead to
  a crash. Instead, print a warning and set node->table to NULL just like
  it is done if the .ibd file is missing.

  branches/zip: When the server crashes while freeing an externally stored
  column of a compressed table, the BTR_EXTERN_LEN field in the BLOB pointer
  will be written as 0.  Tolerate this in the functions that deal with
  externally stored columns.  This fixes Issue #80 and was posted at rb://26.

  Note that the clustered index record is always deleted or purged last,
  after any secondary index records referring to it have been deleted.

  btr_free_externally_stored_field(): On an uncompressed table, zero out
  the BTR_EXTERN_LEN, so that half-deleted BLOBs can be detected after
  crash recovery.

  btr_copy_externally_stored_field_prefix(): Return 0 if the BLOB has been
  half-deleted.

  row_upd_ext_fetch(): Assert that the externally stored column exists.

  row_ext_cache_fill(): Allow btr_copy_externally_stored_field_prefix()
  to return 0.

  row_sel_sec_rec_is_for_blob(): Return FALSE if the BLOB has been half-deleted.
  This is correct, because the clustered index record would have been deleted
  or purged last, after any secondary index records referring to it had been
  deleted.
