(we don't need to port the actual code from 5.1;
5.5+ do the relevant things differently, but correctly. the
test obviously is so it stays that way.)

mysql-test/r/variables.result:
  add test case.
mysql-test/t/variables.test:
  add test case.
strings/CHARSET_INFO.txt:
  clarify documentation

43233/55794.

mysql-test/r/change_user.result:
  Don't use -1 integer wrap around. It used to work, but now we do what's
  actually in the documentation. In tests, we now use DEFAULT or the
  numeral equivalent (as we do in the 5.6 tests).
mysql-test/r/key_cache.result:
  Can't drop default key case is an error now, not a warning, for compatibility
  with 5.6.
mysql-test/r/variables.result:
  Can't drop default key case is an error now, not a warning, for compatibility
  with 5.6.
mysql-test/t/change_user.test:
  Don't use -1 integer wrap around. It used to work, but now we do what's
  actually in the documentation. In tests, we now use DEFAULT or the
  numeral equivalent (as we do in the 5.6 tests).
mysql-test/t/key_cache.test:
  Can't drop default key case is an error now, not a warning, for compatibility
  with 5.6.
mysql-test/t/variables.test:
  Can't drop default key case is an error now, not a warning, for compatibility
  with 5.6.
sql/mysqld.cc:
  0 is a legal (albeit magic) value: "drop key cache."
sql/set_var.cc:
  bound_unsigned() can go now, it was just a kludge until things are done
  The Right Way, which they are now.
  
  Can't drop default key case is an error now, not a warning, for compatibility

tests/mysql_client_test.c:
  Don't use -1 integer wrap around. It used to work, but now we do what's
  actually in the documentation. In tests, we now use DEFAULT or the
  numeral equivalent (as we do in the 5.6 tests).

Problem : The build might fail with 
make[2]: *** No rule to make target `../sql/z',
needed by `sql/mysqld_dtrace_all.o'.  Stop.
if one of plugins would depends on system libz 
library

Fix: Filter out non-static dependent libraries
when dtracing static libs

MSI: Only call custom action if REMOVE=ALL is specified, this avoids accidential removing services if 
feature states are modified (reported by Iggy)

The problem was MFC header file includes into the resource definition file (CustomAction.rc)
afxres.h is not available with VS Express.

The fix is to remove resource file from compilation and souce code repository. version of
custom action dll is of no interest for anyone, it is internal dll kept inside the MSI.

EXCEPTIONS-CLIENT from all the places.

In case of low memory sort buffer QUICK_INDEX_MERGE_SELECT creates
temporary file where is stores row ids which meet QUICK_SELECT ranges
except of clustered pk range, clustered range is processed separately.
In init_read_record we check if temporary file is used and choose
appropriate record access method. It does not take into account that
temporary file contains partial result in case of QUICK_INDEX_MERGE_SELECT
with clustered pk range.
The fix is always to use rr_quick if QUICK_INDEX_MERGE_SELECT
with clustered pk range is used.


mysql-test/suite/innodb/r/innodb_mysql.result:
  test case
mysql-test/suite/innodb/t/innodb_mysql.test:
  test case
mysql-test/suite/innodb_plugin/r/innodb_mysql.result:
  test case
mysql-test/suite/innodb_plugin/t/innodb_mysql.test:
  test case
sql/opt_range.h:
  added new method
sql/records.cc:
  The fix is always to use rr_quick if QUICK_INDEX_MERGE_SELECT
  with clustered pk range is used.

cmake/do_abi_check.cmake:
  Put temporary files in ${BINARY_DIR} rather than in source directory.
  Slight reformatting for readability of commands.

 - Make the cmake files depend on VERSION, causing
   cmake rerun when VERSION changes

mysql-test/suite/sys_vars/t/shared_memory_base_name_basic.test:
  The server shared memory name is located in the server's
  temporary directory, not in the mysqltest one.
sql/sql_show.cc:
  */ ends a comment, add space to avoid problems.

test case to give valgrind warnings.

The problem was that when comparing two MDL key buffers using
memcmp(), 1 was added to the buffer length. However, this was
no longer needed since the buffer length already included the
'\0' terminator.

Remove some more files which are unused.


win/README:
  This information is dated and does not apply anymore.
win/create_manifest.js:
  Unused.
win/mysql_manifest.cmake:
  Unused.

and related small fixes.

mysql-test/t/user_var.test:
  test for bug
sql/field_conv.cc:
  From the C standard, memcpy() has undefined behaviour if to->ptr==from->ptr
sql/item_func.cc:
  In the case of BUG#56138, entry->value==ptr in which case memcpy()
  has undefined results per the C standard.
sql/sql_select.cc:
  Work around a bug in old gcc

Remove some more leftovers from the initial removal:

o Update relevant mentions of configure.in throughout
the source code.

o Remove win/configure.js, which at this point just
duplicates logic already present in CMake based build
system.

o Remove support files which relied on the autotools
build system. In any case, MySQL is no longer officially
supported on SCO.

o Remove files which are no longer part of the build.
