Improvements in socket buffer sizes

HULFT
8.0.0

The fields in the System Environment Settings are now improved and sectioned into fields:The buffer sizes can be specified separately for sending and receiving.

In addition, the default value for the conventional Socket Buffer Size (socksize) was "12288", but that for Socket Buffer Size for Data Sending (sndsocksize) and Socket Buffer Size for Data Receiving (rcvsocksize) are now "0".
