Patch seems to be proper. I'll review and commit it later.

Description:
------------
zend_do_import incorrectly compares an import name to global class
names.  It should compare EG(current_namespace) . '::' . importname to
check for conflicting names.

This is because when inside a namespace, to the user, import should
behave in the same manner as a class declaration.  This code:

<?php
namespace Foo;
class Exception {}
?>

creates Foo::Exception.

This code:

<?php
namespace Foo;
import Blah::Exception as Exception;
?>

Should essentially work as if the user had typed:

<?php
namespace Foo;
import Blah::Exception as Foo::Exception;
?>

In other words, it should resolve future uses of "Exception" to
"Blah::Exception" and "::Exception" to "Exception" and not complain
about "Exception" conflicting with "::Exception"

Patch for PHP 5:
http://pear.php.net/~greg/fix_import.patch.txt
Patch for PHP 6:
http://pear.php.net/~greg/fix_import.php6.patch.txt

Reproduce code:
---------------
testme.php:
<?php
namespace Blah;
class Exception extends ::Exception {}
?>

test.php:
<?php
namespace Foo;
include 'testme.php';
import Blah::Exception;
$a = new Exception;
throw $a;
?>



Expected result:
----------------
Fatal error: Uncaught exception 'Blah::Exception' in
/home/cellog/workspace/php5/test.php:5
Stack trace:
#0 {main}
  thrown in /home/cellog/workspace/php5/test.php on line 5


Actual result:
--------------
Fatal error: Import name 'Exception' conflicts with defined class in
/home/cellog/workspace/php5/test.php on line 4
