Reset history when we reenable logging for transactional tables (safety fix)

mysql-test/r/maria2.result:

mysql-test/valgrind.supp:

storage/maria/ma_extra.c:
  Remove table from trnman list if we are going to drop or rename it; We don't want not existing shares in the list when we do commit!
storage/maria/ma_recovery.c:
  Ensure that info->state don't point to history event when we disable logging for a table;  This is needed as alter table will first do commit and then unlock, which would cause us to access a non existing object when we reenable logging.
  Reset history when we reenable logging (safety fix)
storage/maria/ma_state.c:
  Do less work when share->now_transactional is not set. (Safety fix)

  Added function to reset history to current context
storage/maria/ma_state.h:
  Prototypes for new function

used TL_WRITE_CONCURRENT_INSERT though they may update/delete a row. This could cause concurrent SELECTs
to see a changing table while the SELECT happens, or if the query was made of a group of SELECTs,
some SELECTs would see different versions of the table. And anyway versioning in Maria was so far coded
to support only insertions. REPLACE SELECT, INSERT VALUES ON DUPLICATE KEY UPDATE, LOAD DATA REPLACE
were ok.

mysql-test/r/maria2.result:
  result. Without the code fix, the assertion added to ha_maria::update_row() would fire twice.
mysql-test/t/maria2.test:
  test when INSERT ON DUPLICATE KEY UPDATE and LOAD DATA CONCURRENT REPLACE do update rows
storage/maria/ha_maria.cc:
  Assert that update_row and delete_row never see TL_WRITE_CONCURRENT_INSERT.
  INSERT SELECT ON DUPLICATE KEY UPDATE and LOAD DATA CONCURRENT REPLACE
  must upgrade TL_WRITE_CONCURRENT_INSERT to TL_WRITE because they may update/delete a row.

storage/maria/ha_maria.cc:
  missing DBUG_RETURN

this was true also for INSERT SELECT, UPDATE, DELETE. This fix will be removed when Maria supports COMMIT/ROLLBACK
("Maria 2.0"), because then Maria will trans_register_ha() and so participate in ha_commit_trans().
Without the fix, the assertion added to ha_maria::external_lock() fires many times in *maria*.test.

sql/sql_parse.cc:
  Before sending OK to client, commit transaction in Maria.
storage/maria/ha_maria.cc:
  Assertion added to external_lock() when committing: OK should not have been sent yet (ACI*D*).
  In ha_maria::implicit_commit(), possibility to not create a new transaction, this is used
  before net_end_statement(), when the next step is close_thread_tables();
  in this use case, ha_maria::implicit_commit() should not commit if under LOCK TABLES.
storage/maria/ha_maria.h:
  new prototype

- Fixes key corruption where pages wasn't marked that they contained transid.
- Fixed bug in block record that could create too small rows when transid was removed. This fixed some asserts() when testing block length

Added --abort-source-on-error to the mysql client. (Very helpfull when debugging wrong .sql files)

client/client_priv.h:
  Added enum for new option to mysql
client/mysql.cc:
  Added new option --abort-source-on-error to allow one to get 'source' to stop on error. This is 0 by default, to keep old behaviour.
  Print file name and line number when getting an error when doing source filename
sql/field.cc:
  Removed old dead code
sql/sql_class.cc:

storage/maria/ma_blockrec.c:
  Added checking of min block length to check_directory()
  When creating new directory entry, set length to 0; This ensures that the assert checks() on block lengths works properly.
  Added more DBUG_ASSERT() and more calls to check_directory()
  In get_head_or_tail_page(), send in correct min_block_length. This is now safe as the length of new blocks are now 0
storage/maria/ma_delete.c:
  When moving key to parent page, mark page if key has transid
storage/maria/ma_write.c:
  Fixed bug where _ma_find_last_pos() didn't set int_key->flag.
  Simpilifed code by unrolling loop.

Test for fix made by Monty for BUG#37276 (CHECK TABLE said Invalid key block position: 15731098820608  key
+# block size: 8192  file_length: 425984). Other corruption cases still not fixed.
Without the fix, the test would yield the corruption message in CHECK TABLE.

- lifting a limit: INSERT|REPLACE SELECT and LOAD DATA always prevented versioning, now what do so is if
the table is empty.
- lifting another limit: versioning was disabled if table had more than one unique index

  now when table is empty it does not do versioning, so test hung; inserting one row at start of the test,
  to enable versioning.
sql/sql_parse.cc:
  Maria team wrongly removed this "break", thanks Davi for noticing
storage/maria/ha_maria.cc:
  - We used to prevent versioning in INSERT/REPLACE SELECT and LOAD DATA, because the index rebuild done by
  bulk insert sometimes, is unsafe when versioning is on. Here we change that: in store_lock(), if the table is empty
  (which is required for index rebuild to be used), we disable versioning; in start_bulk_insert(), we don't do
  index rebuild if versioning is enabled.
  - Test for statement-based binlogging was incomplete: statement-based binlogging is on for this statement
  if binlog is open and statement has binlogging enabled and statement is not doing row-based binlogging
storage/maria/ma_open.c:
  Monty and I agreed that it's ok to have versioning on a table with more than one unique index: if an INSERT
  hits a duplicate key when inserting the second index' key, no other thread should be able to touch the 
  first index' just-inserted key, because that key has an uncommitted transaction id, so the first thread
  should have time to remove the first index' key.
