Revision 361084

Introduce sysputpage() to display large page size with human readable format.
Using UI units allows to fit larger numbers in columns.
Stop calling v_page_size - this is a value that doesn't change at runtime.
Renamed WINDOW *wnd to *wd to avoid conflict with global *wnd variable.
Use bit-shift to convert page size to byte.
