Sybase sp_freedevice procedure

Only the short info about Sybase database devices.
Parameters:
min_space – minimum of required space (i.e. 40 will display the devices with >=40M free space)
the_name – the template for the device name (i.e. %mast% will display only master device)

Warning! It was not tested for all possible configurations, so the result could be incorrect on some OS.
