Add support for audit kernel container identifiers to userspace tools.

The first and second add new record types.  The third adds filter
support.  The fourth and 5th start to add search support.

The last is intended for debugging and not for upstream, matching the
kernel /proc read patch.

  AUDIT_FEATURE_BITMAP_CONTAINERID
- change from event_container_id to event_contid internally
- change from container_id to contid and event_container_id to
  event_contid internally
- change command line option from --container-id to --contid

v3
- change from AUDIT_CONTAINER to AUDIT_CONTAINER_ID
- change from AUDIT_CONTAINER_INFO to AUDIT_CONTAINER
- change from AUDIT_CONTAINERID to AUDIT_CONTID

This defines the message number for the audit container identifier
registration record should the kernel headers not be up to date, gives
the record number a name for printing and allows the record to be
interpreted since it is in the 1000 range like AUDIT_LOGIN.

A u64 container identifier has been added to the kernel view of tasks.
This allows container orchestrators to label tasks with a unique
tamperproof identifier that gets inherited by its children to be able to
track the provenance of actions by a container.

Add support to libaudit and auditctl for the AUDIT_CONTID field to
filter based on audit container identifier.  This field is specified
with the "contid" field name on the command line.

Since it is a u64 and larger than any other numeric field, send it as a
string but do the appropriate conversions on each end in each direction.

Add the audit_get_containerid() call analogous to audit_getloginuid()
and audit_get_session() calls to get our own audit container identifier.

This is intended as a debug patch, not to be upstreamed.

+.SH NAME
+audit_get_containerid \- Get a program's container id value
+.SH SYNOPSIS
+.B #include <libaudit.h>
+.sp
+uin32_t audit_get_containerid(void);
+
+.SH DESCRIPTION
+This function returns the task's audit container identifier attribute.
+
+.SH "RETURN VALUE"
+
+This function returns the audit container identifier value if it was set. It will return a \-1 if the audit container identifier is unset. However, since uint64_t is an unsigned type, you will see the converted value instead of \-1.
+
+.SH "ERRORS"
+
+This function returns \-2 on failure. Additionally, in the event of a real error, errno would be set. The function can set errno based on failures of open, read, or strtoul.
+
+.SH "SEE ALSO"
+
+.BR audit_getloginuid (3).
