[NTOS:SE] Reorganize the security manager component
The current state of Security manager's code is kind of a mess. Mainly,
there's code scattered around places where they shouldn't belong and token
implementation (token.c) is already of a bloat in itself as it is. The file has over 6k
lines and it's subject to grow exponentially with improvements, features, whatever
that is.
With that being said, the token implementation code in the kernel will be split
accordingly and rest of the code moved to appropriate places. The new layout will look as
follows (excluding the already existing files):
- client.c (Client security implementation code)
- objtype.c (Object type list implementation code -- more code related to object types
will be put here when I'm going to implement object type access checks in the future)
- subject.c (Subject security context support)
The token implementation in the kernel will be split in 4 distinct files as shown:
- token.c (Base token support routines)
- tokenlif.c (Life management of a token object -- that is Duplication, Creation and
Filtering)
- tokencls.c (Token Query/Set Information Classes support)
- tokenadj.c (Token privileges/groups adjusting support)
In addition to that, tidy up the internal header and reorganize it as well.

/**
* @brief
- * Private helper function responsible for creating a restricted access
- * token, that is, a filtered token from privileges and groups and with
- * restricted SIDs added into the token on demand by the caller.
- *
- * @param[in] Token
- * An existing and valid access token.
- *
- * @param[in] PrivilegesToBeDeleted
- * A list of privileges to be deleted within the token that's going
- * to be filtered. This parameter is ignored if the caller wants to disable
- * all the privileges by specifying DISABLE_MAX_PRIVILEGE in the flags
- * parameter.
- *
- * @param[in] SidsToBeDisabled
- * A list of group SIDs to be disabled within the token. This parameter
- * can be NULL.
- *
- * @param[in] RestrictedSidsIntoToken
- * A list of restricted SIDs to be added into the token. This parameter
- * can be NULL.
- *
- * @param[in] PrivilegesCount
- * The privilege count of the privileges list.
- *
- * @param[in] RegularGroupsSidCount
- * The SIDs count of the group SIDs list.
- *
- * @param[in] RestrictedSidsCount
- * The restricted SIDs count of restricted SIDs list.
- *
- * @param[in] PrivilegeFlags
- * Influences how the privileges should be filtered in an access
- * token. See NtFilterToken syscall for more information.
- *
- * @param[in] PreviousMode
- * Processor level access mode.
- *
- * @param[out] FilteredToken
- * The filtered token, returned to the caller.
+ * Creates the anonymous logon token for the system. The difference between this
+ * token and the other one is the inclusion of everyone SID group (being SeWorldSid).
+ * The other token lacks such group.
*
* @return
- * Returns STATUS_SUCCESS if token token filtering has completed successfully.
- * STATUS_INVALID_PARAMETER is returned if one or more of the parameters
- * do not meet the conditions imposed by the function. A failure NTSTATUS
- * code is returned otherwise.
- *
- * @remarks
- * The final outcome of privileges and/or SIDs filtering is not always
- * deterministic. That is, any privileges or SIDs that aren't present
- * in the access token are ignored and the function continues with the
- * next privilege or SID to find for filtering. For a fully deterministic
- * outcome the caller is responsible for querying the information details
- * of privileges and SIDs present in the token and then afterwards use
- * such obtained information to do any kind of filtering to the token.
+ * Returns the system's anonymous logon token if the operations have
+ * completed successfully.
