Switch from select() to poll() in xenconsoled's IO loop
In Linux select() typically supports up to 1024 file descriptors. This can be
a problem when user tries to boot up many guests. Switching to poll() has
minimum impact on existing code and has better scalibility.
pollfd array is dynamically allocated / reallocated. If the array fails to
expand, we just ignore the incoming fd.
Updated: reset *_pollfd after use.
This fixes regression 14869.
Also remove unused slave_pollfd in strcut domain.
