Problem: calling non-constant argument's val_xxx() methods 
in the ::fix_length_and_dec() is inadmissible.

Fix: call the method only for constant arguments.

An integer overflow in number->string conversion caused completely
wrong output of the number LONGLONG_MIN with gcc 4.2.1.

Fixed by eliminating the overflow, using only operations that are
well-defined in ANSI C.

some platforms

Since the behavior of write(fd, buf, 0) is undefined, it may fail with
EFAULT on some architectures when buf == NULL. The error was propagated
up to a caller, since my_write() code did not handle it properly.

Fixed by checking the 'number of bytes' argument in my_write() and
returning before calling the write() system call when there is nothing
to write.

Fixed the Windows build failures introduced by the patch for bug #31207: Test "join_nested" shows different strategy on IA64 CPUs / Intel's ICC compiler.

Problem: lying to the optimizer that a function (Item_func_inet_ntoa)
cannot return NULL values leads to unexpected results (in the case group
keys creation/comparison is broken). 

Fix: Item_func_inet_ntoa::maybe_null should be set properly.

Previously, UDF *_init functions were passed constant strings with erroneous lengths. The length came from the containing variable's size, not the length of the value itself.
    
Now the *_init functions get the constant as a null terminated string with the correct length supplied too.

CPUs / Intel's ICC compile

The bug is a combination of two problems:

1. IA64/ICC MySQL binaries use glibc's qsort(), not the one in mysys.

2. The order relation implemented by join_tab_cmp() is not transitive,
i.e. it is possible to choose such a, b and c that (a < b) && (b < c)
but (c < a). This implies that result of a sort using the relation
implemented by join_tab_cmp() depends on the order in which
elements are compared, i.e. the result is implementation-specific. Since
choose_plan() uses qsort() to pre-sort the
join tables using join_tab_cmp() as a compare function, the results of
the sorting may vary depending on qsort() implementation.

It is neither possible nor important to implement a better ordering
algorithm in join_tab_cmp(). Therefore the only way to fix it is to
force our own qsort() to be used by renaming it to my_qsort(), so we don't depend
on linker to decide that.

This patch also "fixes" bug #20530: qsort redefinition violates the
standard.

Problem: currently, UCS-2 cannot be used as a client character set.

Fix: raise an error if one attempts to set it to USC-2.
