When a table is being updated it has two set of fields - fields required for
checks of conditions and fields to be updated. A storage engine is allowed
not to retrieve columns marked for update. Due to this fact records can't
be compared to see whether the data has been changed or not. This makes the
server always update records independently of data change.

Now when an auto-updatable timestamp field is present and server sees that
a table handle isn't going to retrieve write-only fields then all of such
fields are marked as to be read to force the handler to retrieve them.

An assertion abort could occur for some grouping queries that employed 
decimal user variables with assignments to them.

The problem appeared the constructors of the class Field_new_decimal
because the function my_decimal_length_to_precision did not guarantee
returning decimal precision not greater than DECIMAL_MAX_PRECISION.

The cast operation ignored the cases when the precision and/or the scale exceeded
the limits, 65 and 30 respectively. No errors were reported in these cases.
For some queries this may lead to an assertion abort.

Fixed by throwing errors for such cases.

For GCov builds, if the server crashes, the normal exit handler for writing
coverage information is not executed due to the abnormal termination.

Fix this by explicitly calling the __gcov_flush function in our crash handler.

The SELECT INTO OUTFILE FIELDS ENCLOSED BY digit or minus sign,
followed by the same LOAD DATA INFILE statement, used wrond encoding
of non-string fields contained the enclosed character in their text
representation.

Example:
  SELECT 15, 9 INTO OUTFILE 'text' FIELDS ENCLOSED BY '5';

Old encoded result in the text file:
  5155 595
         ^ was decoded as the 1st enclosing character of the 2nd field;
        ^ was skipped as garbage;
  ^    ^ was decoded as a pair of englosing characters of the 1st field;
      ^   was decoded as traling space of the first field;
    ^^ was decoded as a doubled enclosed character.

New encoded result in the text file:
  51\55 595
  ^   ^ pair of enclosing characters of the 1st field;
    ^^ escaped enclosed character.

AsText() needs to know the maximum number of
characters a IEEE double precision value can
occupy to make sure there's enough buffer space.
The number was too small to hold all possible
values and this caused buffer overruns.
Fixed by correcting the calculation of the 
maximum digits in a string representation of an
IEEE double precision value as printed by 
String::qs_append(double).

            causing update of a different column

Post-pushbuild fix.

bitmap_set_bit() is an inline function in DEBUG builds and
a macro in non-DEBUG builds. The latter evaluates its 'bit'
argument twice. So one must not use increment/decrement operators
on this argument.

Moved increment of pointer out of bitmap_set_bit() call.

Enabling rpl_udf test.
