Buffer over-run on all platforms, crash on windows, wrong result on other platforms,
when rounding numbers which start with 999999999 and have
precision = 9 or 18 or 27 or 36 ...
mysql-test/r/type_newdecimal.result:
New test cases.
mysql-test/t/type_newdecimal.test:
New test cases.
sql/my_decimal.h:
Add sanity checking code, to catch buffer over/under-run.
strings/decimal.c:
The original initialization of intg1 (add 1 if buf[0] == DIG_MAX)
will set p1 to point outside the buffer, and the loop to copy the original value
while (buf0 < p0)
*(--p1) = *(--p0);
will overwrite memory outside the my_decimal object.

Extra fix: 'if (p5 < p5_a + P5A_MAX)' is not portable.
p5 starts out pointing to a static array, then may point
to a buffer on the stack, then may point to malloc()ed memory.

WITH UTF32
The 5.5 version of the UTF32 collation was not enforcing the BMP range that
it currently supports when comparing with LIKE.
Fixed by backporting the checks for the BMP from trunk.
Added a named constant for the maximum character that can have a weight
in the weight table.

Turns out the DBUG_ASSERT added by fix for Bug#11792200 was overly pessimistic:
'stop0' is used in the main loop of do_div_mod, but we only dereference 'buf0'
for div operations, not for mod.

This was a buffer overrun in do_div_mod(), overwriting the internal buffer
of auto variable 'tmp' in Item_func_int_div::val_int.
Result on windows: 'this' is set to zero, and crash.
Ran fine on other platforms (no valgrind warnings),
but this is undefined behaviour on any platform of course.

character closing a string value.

When installing plugins, there is a missing check
for slash (/) in the path on Windows. Note that on
Windows, both / and \ can be used to separate
directories.
This patch fixes the issue by:
- Adding a FN_DIRSEP symbol for all platforms
consisting of a string of legal directory
separators.
- Adding a charset-aware version of strcspn().
- Adding a check_valid_path() function that uses
my_strcspn() to check if any FN_DIRSEP character
is in the supplied string.
- Using the check_valid_path() function in
sql_plugin.cc and sql_udf.cc (which means
replacing the existing test there).

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.

- 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

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.
VERSION:
Add top-level version file.
cmake/mysql_version.cmake:
Get version information from the top-level VERSION file.
Do not cache the version components (MAJOR_VERSION, etc).
Add MYSQL_RPM_VERSION as a replacement for MYSQL_U_SCORE_VERSION.

The crash during boot was caused by a DBUG_PRINT statement in fill_schema_schemata() (in
sql_show.cc). This DBUG_PRINT statement contained several instances of %s in the format
string and for one of these we gave a NULL pointer as the argument. This caused the
call to vsnprintf() to crash when running on Solaris.
The fix for this problem is to replace the call to vsnprintf() with my_vsnprintf()
which handles that a NULL pointer is passed as argumens for %s.
This patch also extends my_vsnprintf() to support %i in the format string.
dbug/dbug.c:
Replace the use of vsnprintf() with my_vsnprintf(). On some platforms
vsnprintf() did not handle that a NULL pointer was given as an argument
for a %s in the format string.
include/mysql/service_my_snprintf.h:

strings/my_vsnprintf.c:

Problem:
- ORDER BY for utf8mb4_bin, utf16_bin and utf32_bin returned
results in a wrong order, because old functions
(supporting only BMP range) were used to handle these collations.
- Additionally, utf16_bin did not sort supplementary characters
between U+D700 and U+E000, as WL#1213 specification specified.
include/m_ctype.h:
Adding prototypes.
mysql-test/include/ctype_filesort2.inc:
Adding a new shared test file.
mysql-test/t/ctype_utf8mb4.test:
Adding tests.
strings/ctype-ucs2.c:
- Fixing my_strncoll[sp]_utf16_bin to compare
binary representation instead of code points,
to make columns with indexes sort correct.
- Fixing my_collation_handler_utf32_bin and
my_collation_handler_utf16_bin to use new
functions.
strings/ctype-utf8.c:
- Adding my_strnxfrm[len]_unicode_fill_bin()
to handle utf8mb4_bin, utf16_bin and utf32_bin,
using 3 bytes per weight.
This function also performs special reordering in case of utf16_bin.
- Fixing my_collation_utf8mb4_bin handler to use the
new function.
