[PATCH ghau51/ghau40 v6 0/7] add support for audit container identifier

[Richard Guy Briggs]

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 6th is to read the calling process' audit container identifier from
the /proc filesystem matching the kernel /proc read patch.

The last is to learn the audit container identifier of the process that
signals the audit daemon.
