3033ea85a2 Bug #42434: license of mysys MD5 implementation is not GPL-compatible
Took the Xfree implementation (based on the same rewrite as the NDB one)
and added it instead of the current implementation.
Added a macro to make the calls to MD5 more streamlined.

- Remove bothersome warning messages.  This change focuses on the warnings 
that are covered by the ignore file: support-files/compiler_warnings.supp.

704b4845aa merge of 5.1-main into 5.1-maria. Myisam->Maria change propagation will follow.
There were so many changes into mtr (this is the new mtr coming) that I rather
copied mtr from 6.0-main here (at least this one knows how to run Maria tests).
I also fixed suite/maria tests to be accepted by the new mtr.

mysys/thr_mutex.c:
  adding DBUG_PRINT here, so that we can locate where the warning is issued.

When substituting system constant functions with a constant result

collation) if the result of the system constant function was NULL.

730f53f0d2 Bug#35848: UUID() returns UUIDs with the wrong time
offset for time part in UUIDs was 1/1000 of what it
should be. In other words, offset was off.

Also handle the case where we count into the future
when several UUIDs are generated in one "tick", and
then the next call is late enough for us to unwind
some but not all of those borrowed ticks.

Lastly, handle the case where we keep borrowing and
borrowing until the tick-counter overflows by also
changing into a new "numberspace" by creating a new
random suffix.

mysql-test/r/func_misc.result:
  Show that time-part of UUIDs is correct now.
mysql-test/t/func_misc.test:
  Show that time-part of UUIDs is correct now
  by replicating the C-code's resultin SQL.
  Results also decode to expect date-data on
  command-line (external validation).
  
  No test for unwinding of borrowed ticks as
  this a) is a race and b) depends on what timer
  we get.
sql/item_strfunc.cc:
  correct offset for date/time-part of UUID.
  also make sure that when we counted into
  the future earlier (several UUIDs generated
  in same tick), we only give back as many
  "borrowed" ticks as we can without duplicating
  past timestamps. If our tick-counter overflows
  before we can give back, or if the system-clock
  is set back (by user or Daylight Saving Time),
  we create a new random suffix to avoid
  collisions and clear the tick-counter.

66367aeea8 Fixed bug #36488: regexp returns false matches, concatenating
with previous rows.

The WHERE clause containing expression:
  CONCAT(empty_field1, empty_field2, ..., 'literal constant', ...)
    REGEXP 'regular expression'
may return wrong matches.

Optimization of the CONCAT function has been fixed.

mysql-test/t/func_concat.test:
  Added test case for bug #36488.
sql/item_strfunc.cc:
  Fixed bug #36488.
  The Item_func_concat::val_str method is optimized to
  use first non-empty argument of the CONCAT function for in-place
  result accumulation. This optimization is acceptable if that
  first argument is not a constant.
  However, current implementation checks this condition only for
  the first actual argument of the CONCAT function.
  So, the Item_func_concat::val_str method can corrupt values
  of, for example, literal strings by appending random data.
  
  The Item_func_concat::val_str method has been modified to take
  into account the ability to be modified in-place for the first
  non-empty argument.

a3e83048a3 Fix for Bug#30217: Views: changes in metadata behaviour
between 5.0 and 5.1.
  
The problem was that in the patch for Bug#11986 it was decided
to store original query in UTF8 encoding for the INFORMATION_SCHEMA.
This approach however turned out to be quite difficult to implement
properly. The main problem is to preserve the same IS-output after
dump/restore.
  
So, the fix is to rollback to the previous functionality, but also
to fix it to support multi-character-set-queries properly. The idea
is to generate INFORMATION_SCHEMA-query from the item-tree after
parsing view declaration. The IS-query should:
  - be completely in UTF8;
  - not contain character set introducers.
  
For more information, see WL4052.

819eaead10 Fix for a BUG#31898: 16M memory allocations for user variables
in stored procedure.

The problem was that MySQL used unnecessarily large amounts of
memory if user variables were used as an argument to CONCAT or
CONCAT_WS -- 16M per each user variable used.

Technically, it happened because MySQL used the following
allocation strategy for string functions to avoid multiple
realloc() calls: in the virtual operation fix_length_and_dec()
the attribute max_length was calculated as a sum of max_length
values for each argument.

Although this approach worked well for small (or fixed) data types,
there could be a problem if there as a user variable among
the arguments of a string function -- max_length of the function
would be 16M (as the max_length of a user variable is 16M).

Both CONCAT() and CONCAT_WS() functions suffer from this problem.

The fix is to do not use meta-data for allocating memory.
The following strategy is proposed instead: allocate the exact
length of the result string at the first record, double the amount
of memory allocated when it is required.

No test case for this bug because there is no way to test memory
consumption in a robust way with our test suite.
