Access check is an expensive operation, that is, whenever an access to an object is performed an access check has to be done to ensure the access can be allowed to the calling thread who attempts to access such object. Currently SepAnalyzeAcesFromDacl allocates a block of pool memory for access check rights, nagging the Memory Manager like a desperate naughty creep. So instead initialize the access rights as a simple variable in SepAccessCheck and pass it out as an address to SepAnalyzeAcesFromDacl so that the function will fill it up with access rights. This helps with performance, avoiding wasting a few bits of memory just to hold these access rights. In addition to that, add a few asserts and fix the copyright header on both se.h and accesschk.c, to reflect the Coding Style rules.
