Elliott Hughes 0fe3b67024 Fix logd's implicit dependency on libsysutils.
We're trying to remove the implicit dependency on libsysutils that *all*
code has via the symlink in system/core/include/, but netd and logd have
code that #includes the headers without declaring the dependency (which
works out in the end because their executables declare the dependency).

Bug: http://b/165825252

Tom Cherry 0efb410013 logging: Use more inclusive language.
Also generic syntax clean up and removing some unused aspects (sorting
the list and the TODO increasing performance based on this sorting).

Tom Cherry a3c5ff5d3f logd: move current sequence from LogBufferElement to LogBuffer
This is required for tests that are aware of sequence numbers to pass;
each new LogBuffer instance should start from sequence = 1, which
isn't the case if the current sequence number is a static.

Test: unit tests

Tom Cherry 1322472ad0 logd: use a std::list<> of values not pointers
This saves 4 or 8 bytes off of each log message for 32 bit or 64 bit
devices respectively.  In practice, this actually saves more, due to
avoiding heap fragmentation.

Averaging over 5 runs of the LogBufferTest.random_messages unit test
(32 bit), this change results in 8k less memory used when 1000 logs
are logged and results in 260k less memory used when 10000 logs are
logged.

Test: check memory usage during LogBufferTest.random_messages

Tom Cherry a26f7dffe5 logd: refactor chatty deduplication logging
This code and comment is hard to follow, despite the operation being
simple, so refactor the code to be easier to follow.

Also, use std::unique_ptr instead of raw pointers as appropriate.

Tom Cherry 283c9a1c00 logd: remove SocketClient from LogBuffer and LogBufferElement
In the future, we'll want to be able to write to outputs that are not
necessarily a libsysutils SocketClient, for example host tests of
LogBuffer.  Therefore, we add a LogWriter class to be used instead of
SocketClient.

Tom Cherry d5b3838dbc logd: make LogBuffer an interface
We may use different implementations of LogBuffer in the future, so we
make it interface and create a concrete ChattyLogBuffer class that
implements it.
