- logDmesg method consumes considerable memory
resources (typically 128KB depending on kernel)
- In the future (eg: klogd, syslogd) there may be need to
feed multiple logs or threads with the retrieved data.
- By moving the actions of logDmesg into the mainline that
instantiates the thread objects, we can leverage a single
allocation of the the kernel log allocation.
- logDmesg (private) is replaced with log (public) which
has a more useful and descriptive purpose for the class.

Impose a limit of 20 selinux denials per second. Denials beyond
that point don't add any value, and have the potential to cause
crashes or denial of service attacks.
Do some other misc cleanup while I'm here.

- auditd spawn log copy to events and main
- logcat delete events as one of the default logs
- debuggerd do not collect events.
- squish multiple spaces
- switch from strcpy to memmove for overlapping buffers

- auditd switch to recording logs to events log id
- logcat add events as one of the default logs
- debuggerd collect events log as well.
ToDo: debuggerd & bugreport collect intermixed logs.

Initial commit for an audit daemon that writes kernel audit
messages to the Android logger. The daemon searches dmesg
for all lines that contain "audit" and writes them. Then
receiving the messages from the netlink socket.
It also formats the messages so they are compatable with
ausearch (type=<t> <m> format)
