logd: security buffer only AID_SYSTEM reader
- limit AID_SYSTEM uid or gid to read security buffer messages
- adjust liblog tests to reflect the reality of this adjustment
To fully test all security buffer paths and modes
$ su 0,0,0 /data/nativetest/liblog-unit-tests/liblog-unit-tests --gtest_filter=liblog.__security*
$ su 1000,1000,1000 /data/nativetest/liblog-unit-tests/liblog-unit-tests --gtest_filter=liblog.__security*
$ su 2000,2000,2000 /data/nativetest/liblog-unit-tests/liblog-unit-tests --gtest_filter=liblog.__security*
ToDo: Integrate the above individually into the gTest Q/A testing

logd: wakeup on wrap or timeout
If a timeout is specified for the reader, then go to sleep
with the socket open. If the start time is about to get
pruned in the specified log buffers, then wakeup and dump
the logs; or wakeup on timeout, whichever comes first.

logd: replace internal CLOCK_MONOTONIC use with sequence numbers
- switch to simpler and faster internal sequence number, drops
a syscall overhead on 32-bit platforms.
- add ability to break-out of flushTo loop with filter return -1
allowing in reduction in reader overhead.

* Merge conflicts
* rename new syslog daemon to logd to prevent confusion with bionic syslog
* replace racy getGroups call with KISS call to client->getGid()
* Timestamps are filed at logging source
* insert entries into list in timestamp order

* Added region locking around LogWriter list
* separate threads for each writer
* /dev/socket/logd* permissions
