[ SEMANAGE ] Seuser database

[Ivan Gyurdiev <ivg2@cornell.edu>]

[-- Attachment #1: Type: text/plain, Size: 417 bytes --]

Attached patch adds seuser database and files (parse/print stubbed).
Unfortunately I can't initialize the record table yet, because it does 
not support
passing the handle to records at this time (and my new seuser
record takes the handle as argument).

Also adds things I forgot in last patch that added interfaces/booleans
(headers for interfaces and boolean file databases, initialization in 
the handle, etc..)
