Bug description:Add temp directory setting which is used by tempnam(), 
sys_get_temp_dir(), etc.

Description:
------------
Need to be able to set the location of the temporary directory for a
VirtualHost using php_admin_value.

This is especially important when you have multiple VirtualHosts that are
locked down with open_basedir so that they are not able to read the files
in the currently shared temporary directory.

tempnam() and sys_get_temp_dir() should pull the value from this PHP
setting so that no code modifications are needed. For backward
compatibility, the current default value of the temporary directory can be
used to set the default value for the PHP setting.

Test script:
---------------
<?php
// Make sure to put this line in your vhost config!
// php_admin_value tmp_dir "/www/myvhost/tmp"
//
// Create a temporary file in the temporary 
// files directory using sys_get_temp_dir()
echo sys_get_temp_dir() . PHP_EOL;
echo tempnam(null, 'Tux') . PHP_EOL;
?>

Expected result:
----------------
/www/myvhost/tmp
/www/myvhost/tmp/TuxDRhRIg


Actual result:
--------------
/tmp
/tmp/TuxDRhRIg
