Socket leak + select overflow in HDHomeRun support

Socket leak + select overflow in HDHomeRun support.

Socket leak is due to a missing close() in hdhomerun_discover.c detecting local IP addresses.

Select overflow occurs when the system has allocated over 1024 sockets to mythtv.

Problem is noticeable when EIT support is enabled - mythbackend can crash or stop recording within a few days.

The attached patch makes the following changes:

hdhomerun_control: remove select code and tweak timeout setting.

hdhomerun_discover: remove select code and configure sockets to be non-blocking. add missing close call to fix socket leak.
