Fix some bad code in mysqltest.c and mysql-test-run.pl which could cause segfault / wrong LD_LIBRARY_PATH settings.


client/mysqltest.c:
  Remove vsnprintf() and DBUG_PRINT from die() function, as it's not portable to Windows, and it's not allowed to call vsnprintf() and then vfprintf() with the same args.
  
  Can't just print the buffer here, because the buffer is a fixed size.  If the message is longer than will fit int he buffer, it would get truncated on Unix, and the full thing would be printed on Windows.  This DBUG_PRINT isn't important enough for this hassle, so just get rid of it.
mysql-test/mysql-test-run.pl:
  Remove bogus quoting of $ENV{LD_LIBRARY_PATH} and $ENV{DYLD_LIBRARY_PATH} in environment_setup().

BUG#21524 ER_CANT_OPEN_LIBRARY output message used to confuse mysqltest on Solaris. Varying part of the message is now suppressed 


mysql-test/r/ps.result:
  ps.result updated
mysql-test/t/ps.test:
  The error code and the additional output grepped out of ER_CANT_OPEN_LIBRARY message due to the output varies across different platforms

mysql-test/r/ps.result:
  brand new ps.result recorded out of updated ps.test output
mysql-test/t/disabled.def:
  ps.test enabled anew
mysql-test/t/ps.test:
  ps.test updated to ensure FLUSH/RESET are not allowed in stored functions at both parse and execution time

When the client program had its stdout file descriptor closed by the calling
shell, after some amount of work (enough to fill a socket buffer) the server 
would complain about a packet error and then disconnect the client.

This is a serious security problem.  If stdout is closed before the mysql is
exec()d, then the first socket() call allocates file number 1 to communicate
with the server.  Subsequent write()s to that file number (as when printing
results that come back from the database) go back to the server instead in 
the command channel.  So, one should be able to craft data which, upon being
selected back from the server to the client, and injected into the command
stream become valid MySQL protocol to do something nasty when sent /back/ to 
the server.

The solution is to close explicitly the file descriptor that we *printf() to, 
so that the libc layer and the OS layer both agree that the file is closed.

  If standard output is not open (specifically, if dup() of its file number 
  fails) then we explicitly close it so that future uses of the file descriptor
  behave correctly for a closed file.
