argument can lead to a wrong result.

md5() and sha() functions treat their arguments as case sensitive strings.
But when they are compared their arguments were compared as a case
insensitive strings which leads to two functions with different arguments
and thus different results to being identical. This can lead to a wrong
decision made in the range optimizer and thus lead to a wrong result set.

Item_func_md5::fix_length_and_dec() and Item_func_sha::fix_length_and_dec()
functions now set binary collation on their arguments.


sql/item_strfunc.cc:
  Fixed bug#15351: Wrong collation used for comparison of md5() and sha()
  argument can lead to a wrong result.
  Item_func_md5::fix_length_and_dec() and Item_func_sha::fix_length_and_dec()
  functions now set binary collation on their arguments.

 - A segfault occured when the function 'kill_server' called 
   'my_sigset' with signal number 0. 'my_sigset' is a macro which
   uses 'sigaction' to install the signal handler with an invalid
   signal number will on most platforms return EINVAL but yields
   a segfauilt on IRIX 6.5
 - The server crash was detected by mysqld_safe and it was restarted although
   a shutdown was requested.

on some platforms.

  koi8r encoding to name tables is changed for latin1 for the former does not work

  The effect of the test remains: a test table is named to have multibyte utf8 representation,
  which is the essence of the bug.
