Some changes that make things more elegant in 6.0,
backported so the code is mostly the same in 5.1,
for easier maintainence.

sql/set_var.cc:
  Backporting some changes to 5.1 so the code is
  mostly the same in both versions. Less to learn!

In STRICT mode, out-of-bounds values caused an error message
to be queued (rather than just a warning), without any further
error-like processing happening. (The error is queued during
update, at which time it's too late. For it to be processed
properly, it would need to be queued during check-stage.)
The assertion rightfully complains that we're trying to send
an OK while having an error queued.

Changeset breaks a lot of tests out into check-stage. This also
allows us to send more correct warnings/error messages.

sql/set_var.cc:
  cleanup: fold get_unsigned() and fix_unsigned() into one,
  as well as all the semi-common code from the ::check
  functions.

*with --with-charset=utf8*

Problem: wrong LONG TEXT field length is sent to a client 
when multibyte server character set used.

Fix: always limit field length sent to a client to 2^32,
as we store it in 4 byte slot.

Note: mysql_client_test changed accordingly.


sql/protocol.cc:
  Fix for bug#19829:make test Failed in mysql_client_test 
  *with --with-charset=utf8*
    - limit field length sent to client to UINT_MAX32 as 
      it may exceeds 32 bit slot for LONG TEXT fields if
      thd_charset->mbmaxlen > 1.
tests/mysql_client_test.c:
  Fix for bug#19829:make test Failed in mysql_client_test
  *with --with-charset=utf8*
    - checking field members have in mind that field length
      is limited to UINT_MAX32.

usermode address space limit.

Fix: use /LARGEADDRESSAWARE link option when linking 32 bit
executables

for bug #15936.

On some platforms fenv.h may #undef the min/max macros
defined in my_global.h.

Fixed by moving the #include directive for fenv.h from
mysqld.cc to my_global.h before definitions for min/max.

include/my_global.h:
  Moved #include <fenv.h> from mysqld.cc.
sql/mysqld.cc:
  Moved #include <fenv.h> to my_global.h.

In the output message for --help entry for -H --HELP was missing.
Added this entry while printing the help text.

storage/myisam/myisamchk.c:
  Added entry for -H --HELP while printing message for -? --help

Revised the test to include a test of completion_type = 1 as well as making the test more readable / worthwhile
Removed the master.opt file as it was redundant / unnecessary.

mysql-test/suite/sys_vars/t/completion_type_func-master.opt:
  Removed as redundant.  Test uses include/have_innodb.inc.

      
There was a problem when a DELIMITER COMMAND is not the first 
command on the line. I this case an extra line feed was added
to the glob buffer and this was causing subsequent attempts 
to enter this delimiter to fail.
Fixed by not adding a new line to the glob buffer if the 
command being added is a DELIMITER

  Bug #31060: Don't add a new line if DELIMTER is added to
  the glob buffer
