* cygheap.h (init_cygheap::luid): Remove. * mmap.cc (mlock): Accommodate parameter change in call to push_thread_privilege. (munlock): Ditto. * ntdll.h (STATUS_NOT_ALL_ASSIGNED): Define. (NtAdjustPrivilegesToken): Declare. * sec_helper.cc (cygpriv): Reorder to match numerical privilege order. (privilege_luid): Take job of privilege_luid_by_name, using new cygpriv. (privilege_luid_by_name): Remove. (privilege_name): Accommodate new cygpriv array. (set_privilege): Call NtAdjustPrivilegesToken to avoid using advapi32. Accommodate changes to privilege_name. (set_cygwin_privileges): Simplify. Don't try to set SE_CREATE_GLOBAL_PRIVILEGE on systems not supporting it. * security.cc (sys_privs): Reorder to match numerical privilege order. Use real privilege values as defined in security.h. (get_system_priv_list): Drop unused grp_list argument. Create list of privileges according to new wincapc::max_sys_priv value. (get_priv_list): Call privilege_luid instead of privilege_luid_by_name. Make priv a local value instead of a pointer. (create_token): Accommodate parameter change in call to push_self_privilege. (lsaauth): Ditto. (check_access): Use privilege values directly instead of calling privilege_luid. * security.h: Define real privilege values. (cygpriv_idx): Remove. (privilege_luid): Change declaration. (privilege_luid_by_name): Drop declaration. (set_privilege): Change declaration. (set_process_privilege): Drop definition.

same as wincap itself. Otherwise the capability changes made in
wincapc::init() are not propagated to any subsequently started process
in the same session. I'm only writing this longish comment because I'm
puzzled that this has never been noticed before... */
