Update of VC++ project files.

New multi-key-cache handling. This was needed becasue the old one didn't work reliable with MERGE tables.
ALTER TABLE table_name ... CHARACTER SET  ... now changes all char/varchar/text columns to the given character set
(One must use ALTER TABLE ... DEFAULT CHARACTER SET ... to change the default character set)
Fixed that have_compress is detected properly (fixes problems with func_compress.test on platforms without zlib)
New syntax for CACHE INDEX ('keys' is optional if no index name is given and one mentions the key cache name only ones)
Removed compiler warnings
Added mysql_set_server_option() to allow clients like PHP to easaily set/reset the multi-statement flag.

Cleaned up (and disabled part of) date/time/datetime format patch. One can't anymore change default read/write date/time/formats.
This is becasue the non standard datetime formats can't be compared as strings and MySQL does still a lot of datetime comparisons as strings
Changed flag argument to str_to_TIME() and get_date() from bool to uint
Removed THD from str_to_xxxx functions and Item class.
Fixed core dump when doing --print-defaults
Move some common string functions to strfunc.cc
Dates as strings are now of type my_charset_bin instead of default_charset()
Introduce IDENT_QUOTED to not have to create an extra copy of simple identifiers (all chars < 128)
Removed xxx_FORMAT_TYPE enums and replaced them with the old TIMESTAMP_xxx enums
Renamed some TIMESTAMP_xxx enums to more appropriate names
Use defines instead of integers for date/time/datetime string lengths
Added to build system and use the new my_strtoll10() function.

Remove wait_if_global_read_lock on commit as this can cause deadlocks

is involving an assembly function.
Testcase was BUG#1194
SELECT @A:=1; SELECT @A, @A:=1;

Fixed bug in ALTER TABLE ... MODIFY integer-column
Added ref_or_null optimization (needed for subqueries)

Allow syntax CREATE TABLE t1 (LIKE t2)

Call pthread_mutex_destroy() on not used mutex.
Changed comments in .h and .c files from // -> /* */
Added detection of mutex on which one didn't call pthread_mutex_destroy()
Fixed bug in create_tmp_field() which causes a memory overrun in queries that uses "ORDER BY constant_expression"
Added optimisation for ORDER BY NULL

not yet tested - will not be pushed for a few hours - need to commit in 
order to pull

fixed bug in variable assignment in mysqltest
fixed coredump on conversion from empty blob/text to date
added test case for empty blob conversion to date

Added missing files for innobase to the distribution

Updated manual about INNOBASE and BDB

Added test for ALTER TABLE ORDER BY

Fixes for Innobase
Don't reset whole to-buffer in strxnmov

    fix to make ENCRYPT work
BUILD/compile-pentium-debug
    debug has different warnings
BUILD/FINISH.sh
    save symbol table and dissassembled code with symobls available before strip
    use $do_make for make decision instead of $make to avoid conflict
BUILD/SETUP.sh
    export AM_MAKEFLAGS
    fast is now -fno-omit-frame-pointer, the opposite is now called 
    reckless
configure.in
    fixes to make CRYPT work again
Docs/Makefile.am
    hack to avoid rebuilding the manual on make clean -why does
    Makefile depend on $BUILD_SOURCES, and do we even need BUILD_SOURCES?

    - consolidate common functionality into one place
    - make them detect gmake/make

    make -j 2
mysys/my_open.c
    my_umask is better than 0 - we do not want 0000 files when my_open() is called with O_CREAT
sql/log.cc
    fixed up IO_CACHE to make replication work, not fully yet
sql/log_event.cc
    fixed up IO_CACHE
