Problem: MySQL cp1251 did not support 'U+20AC EURO SIGN'
which was assigned a few years ago to 0x88.

Fix: adding mapping: 0x88 <-> U+20AC 

  @ mysql-test/include/ctype_8bit.inc
  New shared file to test 8bit character sets.

  @ mysql-test/r/ctype_cp1251.result

  Adding tests

  @ sql/share/charsets/cp1251.xml
  Adding mapping

  @ strings/ctype-extra.c
  Regenerating ctype-extra.c using strings/conf_to_src
  according to new cp1251.xml

After dropping and recreating the database specified along with --one-database
option at command line, mysql client keeps filtering the statements even after
the execution of a 'USE' command on the same database.

--one-database option enables the filtering of statements when the current
database is not the one specified at the command line. However, when the same
database is dropped and recreated the variable (current_db) that holds the
inital database name gets altered. This bug exploits the fact that current_db
initially gets set to null value (0) when a 'use db_name' follows the recreation
of same database db_name (speficied at the command line) and hence skip_updates
gets set to 1, which inturn triggers the further filtering of statements.

Fixed by making get_current_db() a no-op function when one_database is set,
and hence, under that condition current_db will not get altered.
Note, however the value of current_db can change when we execute 'connect'
command with a differnet database to reconnect to the server, in which case,
the behavior of --one-database will be formulated using this new database.

Problem: LIKE over an indexed column optimized away good results,
because my_like_range_utf32/utf16 returned wrong ranges for contractions.
Contraction related code was missing in my_like_range_utf32/utf16,
but did exist in my_like_range_ucs2/utf8.
It was forgotten in utf32/utf16 versions (during mysql-6.0 push/revert mess).

Fix:
The patch removes individual functions my_like_range_ucs2,
my_like_range_utf16, my_like_range_utf32 and introduces a single function
my_like_range_generic() instead. The new function handles contractions
correctly. It can handle any character set with cs->min_sort_char and
cs->max_sort_char represented in Unicode code points.

  @ mysql-test/include/ctype_czech.inc
  @ mysql-test/include/ctype_like_ignorable.inc
  @ mysql-test/r/ctype_like_range.result
  @ mysql-test/t/ctype_like_range.test
  Adding tests


modified:

  @ include/m_ctype.h
  - Adding helper functions for contractions.
  - Prototypes: removing ucs2,utf16,utf32 functions, adding generic function.
  @ mysql-test/r/ctype_uca.result
  @ mysql-test/r/ctype_utf16_uca.result
  @ mysql-test/r/ctype_utf32_uca.result
  @ mysql-test/t/ctype_uca.test
  @ mysql-test/t/ctype_utf16_uca.test
  @ mysql-test/t/ctype_utf32_uca.test
  - Adding tests.

  @ strings/ctype-mb.c
  - Pad function did not put the last character.
  - Implementing my_like_range_generic() - an universal replacement
    for three separate functions
    my_like_range_ucs2(), my_like_range_utf16() and my_like_range_utf32(),
    with correct contraction handling.

  @ strings/ctype-ucs2.c
  - my_fill_mb2 did not put the high byte, as previously
    it was used to put only characters in ASCII range.
    Now it puts high byte as well
    (needed to pupulate cs->max_sort_char correctly).
  - Adding DBUG_ASSERT()
  - Removing character set specific functions:
    my_like_range_ucs2(), my_like_range_utf16() and my_like_range_utf32().
  - Using my_like_range_generic() instead of the old functions.

  @ strings/ctype-uca.c
  - Using generic function instead of the old character set specific ones.

  @ sql/item_create.cc
  @ sql/item_strfunc.cc
  @ sql/item_strfunc.h
  - Adding SQL functions LIKE_RANGE_MIN and LIKE_RANGE_MAX,
    available only in debug build to make sure like_range()
    works correctly for all character sets and collations. 

(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.)

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.

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

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.
