Split EF.UST handling from EF.IST and EF.SST

Browse Source 
The existing code had the following serious problems:
* when trying to update EF.SST or EF.IST, it would write to EF.UST !
* shell commands were called ust_* even for the EST/IST files

Let's introduce the proper separation between what is shared and what
is file-specific.
