e11d75e45b BUG#29445 - match ... against () never returns 
Part 2:
Searching fulltext index for a word with boolean mode truncation
operator may cause infinite loop.

The problem was that "smarter index merge" was used with "trunc-words",
which must never happen.

Affects 5.1 only.

31c8efc812 BUG#29445 - match ... against () never returns 
Part 1:
Do not perform index search for a plus-word with truncation operator
in case there are other plus-words in expression.

Specifically this optimization was enforced for expression like
"+word1 +word2*", but wasn't enforced for expression like
"+word1 word2*".

69acbc7759 BUG#29464 - load data infile into table with big5 chinese fulltext index 
hangs 100% cpu

Fulltext parser may fall into infinite loop when it gets illegal
multibyte sequence (or a sequence that doesn't have mapping to unicode).

Affects 5.1 only.

005d8c5284 BUG#25951 - ignore/use index does not work with fulltext 
IGNORE/USE/FORCE INDEX hints were honored when choosing FULLTEXT
index.

With this fix these hints are ignored. For regular indexes we may
perform table scan instead of index lookup when IGNORE INDEX was
specified. We cannot do this for FULLTEXT in NLQ mode.

a247282aa6 Implementation of WL#2486 - 
"Process NATURAL and USING joins according to SQL:2003".

* Some of the main problems fixed by the patch:
  - in "select *" queries the * expanded correctly according to
    ANSI for arbitrary natural/using joins
  - natural/using joins are correctly transformed into JOIN ... ON
    for any number/nesting of the joins.
  - column references are correctly resolved against natural joins
    of any nesting and combined with arbitrary other joins.

* This patch also contains a fix for name resolution of items
  inside the ON condition of JOIN ... ON - in this case items must
  be resolved only against the JOIN operands. To support such
  'local' name resolution, the patch introduces a stack of
  name resolution contexts used at parse time.

NOTICE:
- This patch is not complete in the sense that
  - there are 2 test cases that still do not pass -
    one in join.test, one in select.test. Both are marked
    with a comment "TODO: WL#2486".
  - it does not include a new test specific for the task
