Modularize logd.
Separates logd body into a static library liblogd and virtualize LogBuffer::log to be in a new interface class LogBufferInterface. User could have different implementation. Bug: 37756450 Test: liblog-unit-tests, logd-unit-tests and logcat-unit-tests with (b/37791296). Change-Id: I1504ff0e992744001b5a2e9abd45692d1318a152
