- Massively reduce BSS usage. Let futx_to_utx() dynamically allocate the structure. There is only a very small amount of applications out there that needs to use the utmpx database. Wasting 1 KB on unused structures makes little sense. - Just let getutxid() search for matching ut_id's for any *PROCESS-type. This makes the code a bit more future-proof. - Fix a POSIX-mistake: when reading POSIX and the OpenSolaris implementation, getutxline() must return USER_PROCESS and LOGIN_PROCESS records whose ut_lines match. When reading POSIX, it seems LOGIN_PROCESS should not use ut_line at the first place. I have reported this issue.
