[issue13684] httplib tunnel infinite loop

[luzakiru]

New submission from luzakiru <viscount at inbox.com>:

readline() can return ''. This is handled in most places in httplib but not when a tunnel is used. It leads to a infinite loop that permanently blocks the program while wasting CPU cycles.

For the patch I simply copied the fix that is used elsewhere in the file where readline() is used. It can be fixed in the same way in 2.6.
