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

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.

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.

and related small fixes.

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.

The autotools-based build system has been superseded and
is being removed in order to ease the maintenance burden on
developers tweaking and maintaining the build system.

In order to support tools that need to extract the server
version, a new file that (only) contains the server version,
called VERSION, is introduced. The file contents are human
and machine-readable. The format is:

MYSQL_VERSION_MAJOR=5
MYSQL_VERSION_MINOR=5
MYSQL_VERSION_PATCH=8
MYSQL_VERSION_EXTRA=-rc

The CMake based version extraction in cmake/mysql_version.cmake
is changed to extract the version from this file. The configure
to CMake wrapper is retained for backwards compatibility and to
support the BUILD/ scripts. Also, a new a makefile target
show-dist-name that prints the server version is introduced.

Although ICC identifies itself as GCC, even in version numbers,
it does not support the stpcpy built-in.

Bug : -DBUILD_CONFIG=mysql_release sets SIGNCODE parameter which requires 
singtool.exe (part of Windows SDK)  in order to be able to sign the binaries (
only if valid certificate is found). However singtool is not a part of the SDK shipped
with Visual Studio Express, so the build fails claiming missing singtools.exe

Fix: Do not  use SIGNCODE  wiith VC Express.

Also, fix broken nmake build (*.rc files could not be compiled due to ADD_DEFINITIONS
contaning C/C++ compiler specific flags)

Regression introduced by WL#2649.

Problem: queries with date/datetime columns did not use indexes:
set names non_latin1_charset;
select * from date_index_test
where date_column between '2010-09-01' and '2010-10-01';

before WL#2649 indexes worked fine because charset of 
date/datetime
columns was BINARY which always won.

Fix: testing that collation of the operation matches collation 
of the field is only needed in case of "real" string data types.
For DATE, DATETIME it's not needed.

  Adding tests

  @ sql/field.h
  Adding new method Field_str::match_collation_to_optimize_range()
  for use in opt_range.cc to distinguish between
  "real string" types like CHAR, VARCHAR, TEXT
  (Field_string, Field_varstring, Field_blob)

  and "almost string" types DATE, TIME, DATETIME
  (Field_newdate, Field_datetime, Field_time, Field_timestamp)

  @ sql/opt_range.cc
  Using new method instead of checking result_type() against STRING result.

Note:

  Another part of this problem (which is not regression) 
  is submitted separately (see bug##58329).

Problem:

 nr_of_decimals could read behind the end of the buffer
 in case of a non-null-terminated string, which caused
 valgring warnings.

Fix:

  fixing nr_of_decimals not to read behind the "end" pointer.

modified:

  @ mysql-test/r/xml.result
  @ mysql-test/t/xml.test
  @ sql/item.cc

Fixed a typo in an error message.

leave the table unusable".
 
Failing ALTER statement on partitioned table could have left
this table in an unusable state. This has happened in cases
when ALTER was executed using "fast" algorithm, which doesn't 
involve copying of data between old and new versions of table, 
and the resulting new table was incompatible with partitioning
function in some way.
 
The problem stems from the fact that discrepancies between new 
table definition and partitioning function are discovered only 
when the table is opened. In case of "fast" algorithm this has
happened too late during ALTER's execution, at the moment when
all changes were already done and couldn't have been reverted.
 
In the cases when "slow" algorithm, which copies data, is used 
such discrepancies are detected at the moment new table
definition is opened implicitly when new version of table is
created in storage engine. As result ALTER is aborted before 
any changes to table were done.
 
This fix tries to address this issue by ensuring that "fast"
algorithm behaves similarly to "slow" algorithm and checks
compatibility between new definition and partitioning function 
by trying to open new definition after .FRM file for it has 
been created.
 
Long term we probably should implement some way to check
compatibility between partitioning function and new table
definition which won't involve opening it, as this should
allow much cleaner fix for this problem.
