696817d352 liblog: Statistics truncated to 16384 bytes
- if network read/write broken up, reassemble the pieces.
- Use a 20ms poll to check if a new fragment has been
  sent by the other side.
- fixup logd-unit-tests to take a (simplified) fragment
  from the liblog changes.

d3ba665020 logd: Add logd_test
* Test statistics output, all four main log id types
  are checked to be present, and output is properly
  formatted with header (ascii new-line terminated
  byte count) and trailer (newline formfeed) frames.
* On dev build test dgram_qlen, circumvent if
  liblog benchmarks executed first though.
* Test if kernel and user space loggers are
  present, and if any content has leaked to both.
* test benchmark and use it to verify worst UID pruning

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)

Modified: Mark Salyzyn <salyzyn@google.com>

- 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
