Description:
------------
$GLOBALS["HTTP_RAW_POST_DATA"] or HTTP_RAW_POST_DATA contains a "doubled" contents. For example:

Client posts:
<?xml version="1.0"?><methodCall><methodName>sayhello</methodName><params><param><value><string>Duff</string></value></param></params></methodCall>

Apears in $GLOBALS["HTTP_RAW_POST_DATA"] as:
<?xml version="1.0"?><methodCall><methodName>sayhello</methodName><params><param><value><string>Duff</string></value></param></params></methodCall><?xml version="1.0"?><methodCall><methodName>sayhello</methodName><params><param><value><string>Duff</string></value></param></params></methodCall>

Looks like it is concatenated to the variable twice.

I haven't played with this using binary data but it may explain what is messing up file uploads for some people.

I know the recommended way is now to use php://input but a lot of older code relies on this and it seems to clearly be a bug.
