29d238d2a8 logd: selinux auditd initial commit
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)

- do not start auditd
- merge into logd, stripping unnecessary file logging.
- Convert headers and code to support C++
- Fix bugs in libaudit
- squash timestamp (replace with 0.0) due to duplication
- squash pid due to duplication
- squash comm due to duplication

e457b74ce6 logd: Add minimum time bucket statistics
* Only enabled for dev builds because halves performance.
- Used to establish if /proc/sys/net/unix/max_dgram_qlen
  is appropriate for the platform
  (see logd/LogStatistics.cpp comments)
- enabled if logd.dgram_qlen.statistics is not zero/empty
