  Ensure we don't read a errmsg.sys with a missing required error message;  This change was needed as errmsg.sys may now contain empty error messages between the MySQL and MariaDB error messages.
  If error message file didn't exist and we have not read one in the past, don't continue.
  Give better error message if the errmsg.sys header has changed.
sql/share/errmsg.txt:
  Create new section, starting from 1900, for MariaDB error messages

704f97035f Merged the code of MWL#106 into 5.3
Resolved all conflicts, bad merges and fixed a few minor bugs in the code.
Commented out the queries from multi_update, view, subselect_sj, func_str,
derived_view, view_grant that failed either with crashes in ps-protocol or
with wrong results.
The failures are clear indications of some bugs in the code and these bugs
are to be fixed.

716b64cdb0 Bug#58165: "my_empty_string" gets modified and causes LOAD DATA to fail and
other crashes

Some string manipulating SQL functions use a shared string object intended to
contain an immutable empty string. This object was used by the SQL function
SUBSTRING_INDEX() to return an empty string when one argument was of the wrong
datatype. If the string object was then modified by the sql function INSERT(),
undefined behavior ensued.

Fixed by instead modifying the string object representing the function's
result value whenever string manipulating SQL functions return an empty
string.

Relevant code has also been documented.

76627d5fc3 Bug#57818 string conversion function died
Bug#57913 large negative number to string conversion functions crash
String object which is used as result container of the item
has uninitialized 'str_charset' field. This object
might be used later to preform some internal operations
and str_charset field is involved in these operations.

e53ecf2dc2 Bug#49141: Encode function is significantly slower in 5.1 compared to 5.0
The problem was that the multiple evaluations of a ENCODE or
DECODE function within a single statement caused the random
generator to be reinitialized at each evaluation, even though
the parameters were constants.

The solution is to initialize the random generator only once
if the password (seed) parameter is constant.

a01946373d Fix for bug #21205: Different number of digits for float/double/real in --ps-protocol
Various parts of code used different 'precision' arguments for sprintf("%g") when converting
floating point numbers to a string. This led to differences in results in some cases 
depending on whether the text-based or prepared statements protocol is used for a query.

Fixed by changing arguments to sprintf("%g") to always be 15 (DBL_DIG) so that results are
consistent regardless of the protocol.

This patch will be null-merged to 6.0 as the problem does not exists there (fixed by the
patch for WL#2934).

  Use 15 (DBL_DIG) as a precision argument for sprintf(), as Field_double::val_str() does.

7b8717ace8 Bug#20752: BENCHMARK with many iterations returns too quickly
In BENCHMARK(count, expr), count could overflow/wrap-around.
Patch changes to a sufficiently large data-type. Adds a warning
for negative count values.


mysql-test/r/func_str.result:
  show that a negative 'count' for BENCHMARK(count, expr)
  throws a warning and returns NULL.
mysql-test/t/func_str.test:
  show that a negative 'count' for BENCHMARK(count, expr)
  throws a warning and returns NULL.
sql/item_func.cc:
  use ulonglong rather than ulong in BENCHMARK(count, expr)
  throw warning on negative 'count'; return SQL-NULL.

c1d0dd94bb Fix for Bug#32538: View definition picks up character set,
but not collation.

The problem here was that text literals in a view were always
dumped with character set introducer. That lead to loosing
collation information.

The fix is to dump character set introducer only if it was
in the original query. That is now possible because there 
is no problem any more of loss of character set of string
literals in views -- after WL#4052 the view is dumped 
in the original character set.

e722393f51 Bug #31758 inet_ntoa, oct crashes server with null+filesort
Item_func_inet_ntoa and Item_func_conv inherit 'maybe_null' flag from an
argument, which is wrong.
Both can be NULL with notnull arguments, so that's fixed.

04311fabaa Bug #28550 "Potential bugs related to the return type of the CHAR function".
Since, as of MySQL 5.0.15, CHAR() arguments larger than 255 are converted into multiple result bytes, a single CHAR() argument can now take up to 4 bytes. This patch fixes Item_func_char::fix_length_and_dec() to take this into account.
  
This patch also fixes a regression introduced by the patch for bug21513. As now we do not always have the 'name' member of Item set for Item_hex_string and Item_bin_string, an own print() method has been added to Item_hex_string so that it could correctly be printed by Item_func::print_args().

a07b055b9a Fixed bug #27130. If the third argument of the function SUBSTR was
represented by an expression of the type UNSIGNED INT and this 
expression was evaluated to 0 then the function erroneously returned
the value of the first argument instead of an empty string. 

This problem was introduced by the patch for bug 10963.

The problem has been resolved by a proper modification of the code of
Item_func_substr::val_str.
